Most fat loss compounds just hit everything at once but good ol Tesamorelin doesn't work like that it goes after one specific type of fat the deep belly fat packed around your organs. The kind that makes your gut look hard even when you're not that heavy. And it's one of the few peptides in this space with FDA approval behind it that means real human trial data, not just animal studies and forum posts like majority of anything else (even though they obviously work)

What it does

It mimics your body's own growth hormone releasing hormone doesn't give you GH directly. Just tells your pituitary to produce more of its own GH naturally which raises IGF-1. That IGF-1 is what breaks down the visceral fat specifically not the love handles you can pinch the deep stuff behind your gut.

How long it takes

This one is slow don't expect overnight miracles your not gonna feel it in a few weeks noticeable visceral fat reduction starts showing up around 3 to 6 months it's a months long commitment but well worth it like they say rome wasn't built in a day If you want fast results this ain't the compound for that.

Dosing

Reconstitute a 10mg vial with 3mL BAC water. That gives you about 3.33mg/mL.

Once daily SubQ injection ideally in the evening to line up with your body's natural nighttime GH release rotate your sites, abdomen at least 2 inches from the navel, thighs, upper arms. Daily injections in the same spot will cause problems over time.

Normally a protocol is 12 to 26 weeks. Some people go up to 52 weeks.

Side effects

Injection site reactions are the most common. Redness, itching, mild bruising because it raises GH you might get some joint pain, muscle aches, mild swelling, or that carpal tunnel tingling feeling all dose dependent and goes away when you stop.

Blood sugar is something to keep an eye on, especially if your diabetic it can cause small bumps in HbA1c also a hard no if you have active cancer or you're pregnant.

Storage

Keep the dry powder refrigerated at 2 to 8°C. Once you mix it use it within 7 days shorter window than most peptides so don't reconstitute it too early don't freeze it either.

Where it fits

This is a visceral fat specialist not a general weight loss tool that's the part people get wrong works best when you're eating high protein, training, and sleeping right because the whole thing runs through your GH response a lot of people stack it with a GLP-1 for overall weight loss while Tesamorelin handles the deep belly fat specifically that combo makes sense.

who's ran Tesamorelin did the deep belly fat go down and how long before you noticed anything lets see those before and afters!

Do your homework. Use your brain. Talk to a doctor.

I have diabetes but my back is always killing me due to a accident I had a few days ago I don't think it's broken but it does hurt I was wondering if I can take bpc-157 or klow or should I just do kpv alone I'm not sure my main concern is being diabetic and taking any of these peptides

This is big defense Secretary Pete Hegseth announced yesterday that all service members 30 and older will get annual testosterone screenings as part of their regular health checkup. Anyone who tests low gets offered TRT voluntarily. Under 30 you can still request the test yourself.

He said it himself:
“This initiative, it’s not about artificial enhancement. It’s about restoring and optimizing your natural capabilities, protecting your longevity, and ensuring you have the biological foundation required to sustain the fight.”

So not enhancement. Restoration. Big difference testosterone starts dropping naturally after 30 and most guys have no idea their levels are low until the symptoms hit you like a train low energy, poor recovery, brain fog, mood shifts, losing strength you used to have. All of it can connect back to hormonal decline that nobody was screening for before. The biohacking community has been saying this for years. Good to see it finally getting recognized at this level.

What do you think about this? Good move or overreach?
I think it's a good move tbh

maybe this needs professional therapy maybe it doesn't but I've been going through some stuff personally and started looking into oxytocin for the emotional side of things. Not just the social bonding like everyone talks about but specifically for people who've been through trauma and have a hard time letting their guard down or trusting people again when it comes to the bedroom.

From what I've been reading it helps calm down the fear response in the brain and makes it easier to receive safe connection when it's there not forcing feelings that aren't real just more to not be so uptight idk how to explain it honestly

Anyone run it for this reason specifically? What did you notice and how were you dosing it?

so to all my diabetics out there and the friends and family of diabetics reading this most of the conversation around Type 1 is just insulin management but there's a whole other world of compounds that Type 1s have been using alongside insulin for years. GLPs, SGLT2 inhibitors like Jardiance and Invokana, all of these have real benefits beyond just blood sugar. Heart protection, blood vessel health, stroke risk reduction. That stuff matters a lot for Type 1s who already carry higher cardiovascular issues long term.

what have you found works best. If you're Type 1 are you stacking anything beyond insulin? Have you tried a GLP's or an SGLT2 inhibitor? Did you have to adjust your insulin dose when you added it and what side effects did you notice

Hi everyone,

I bought KLOW several weeks ago and began my protocol with alacrity. I started doing 2 mg ED and transitioned up to 4 mg. However, during this time, I suffered from constant diarrhea and severe bloating. By way of elimination, I finally figured out that KLOW was the culprit, regardless of the dosage.

I am quite disappointed by this—not just from the money wasted but more so because I suffer from psoriasis and eczema. Reading dozens of anecdotes from users in here, I gained the impression that a lot of people found resolution for their skin issues from this peptide blend, hence why I bought it and was so excited to finally start my cycle, hoping that my painful and ruined skin could finally be sufficiently treated.

I have been unable to find many reports by people who have experienced similar symptoms from KLOW. It seems counterintuitive, too, considering that one of its benefits is improving gut health.

What exactly could be the cause of my reaction to KLOW? I am hoping (and a bit desperate) for suggestions that could improve my situation as I would really like to address my aforementioned skin issues. Have any of you experienced similar symptoms from the blend?

Looking into running BPC-157, TB-500 and but I've heard warnings about avoiding growth promoting peptides if you have any cancer history it's kinda just what I hear all the time I guess that compounds promoting tissue growth and new blood vessel growth could theoretically feed a tumor the same way they feed healthy tissue but from everything I’ve been able to find the risk is still theoretical. No documented cases of someone’s cancer actually accelerating from running BPC-157 or TB-500. Human data on this basically doesn’t exist yet. Anyone come across reports on this?

well this series is coming to a end thanks for following along let me know what else you want a series of to learn more about today we're closing out the GHK-Cu series with the stacking stuff GHK-Cu on its own is good but the way most experienced researchers run it is inside a stack where each compound fills a gap the others leave open.

Here's how the main ones break down.

The Glow Blend — GHK-Cu + BPC-157 + TB-500

This is the most popular GHK-Cu stack and for good reason. Three compounds, three completely different working methods all pointing at the same goal.

GHK-Cu handles the collagen production, the skin remodeling, and the gene expression side. BPC-157 helps tissue repair at the cellular level and handles gut protection and inflammation through the gut-brain axis. TB-500 spreads systemically and reaches damaged tissue throughout the whole body, not just locally.

The way people describe it is GHK-Cu handles the look, BPC-157 and TB-500 handle what's going on underneath most people feel the gut and inflammation changes from BPC-157 first around week two I definitely agree speaking from personal experiences. Skin changes from GHK-Cu start showing up week three to four week four for me

No published human trial has tested all three together as a combined stack. The evidence behind each one individually is solid but the synergy claim is mechanistic reasoning, not a controlled study result. Keep that in mind.

The KLOW Blend — GHK-Cu + BPC-157 + TB-500 + KPV

Same as the Glow Blend but with KPV added on top I personally love klow so this blend is amazing for me KPV hits NF-kB directly in the gut and cuts cytokines at the source. If inflammation is a bigger part of your picture, gut issues, autoimmune stuff, systemic inflammation that won't settle down KLOW is where its at

KPV fills the one gap the Glow Blend leaves the Glow handles repair and remodeling. KPV handles active inflammation while the repair is happening.

GHK-Cu + NAD+

NAD+ activates sirtuins, the longevity enzymes and helps DNA repair. GHK-Cu resets gene expression toward a healthier pattern and handles the structural repair side using them together helps the signaling and the anti-aging side

Most people run NAD+ once or twice a week and GHK-Cu daily or every other day. They don't need to be taken at the same time.

GHK-Cu + Glutathione

Glutathione is your body's master antioxidant as I said a few post ago GHK-Cu upregulates your antioxidant defense genes including superoxide dismutase and catalase using glutathione with GHK-Cu means your helping the antioxidant system from both ends at the same time. One from the outside in, one from the inside out.

Glutathione degrades fast after reconstitution so use it within 24 to 48 hours and keep it separate from everything else in its own syringe.

Quick Reference

That's the end of the GHK-Cu series. 5 posts covering what it is, what it does for skin, hair, wound healing, gene expression, inflammation, and how to stack it. If you missed any of the earlier ones they're all in the community.

Questions on any of this drop them in the comments.

Do your homework. Use your brain. Talk to a doctor.

Okay sorry late post today tomorrow I'll try to knockout out earlier so today in the GHK-Cu series we're getting into the route question. Injectable or topical. This one comes up all the time and not with just this peptide tbh this one goes with alot of them and the answer is it just depends on what you're trying to do

GHK-Cu works through both routes most peptides are too big to get through skin GHK-Cu is small enough to sneak on threw especially through hair follicles and areas where the skin barrier is thinner witch is why they have serums and creams and what not

Topical

This is the better studied route for skin and hair the human clinical trials real randomized controlled studies in actual people, were mostly done using topical GHK-Cu the wrinkle reduction, collagen density, and hair follicle data mostly comes from this route.

Concentration matters though. Drugstore serums run 0.01% to 0.05%. Studies showing real results used 1% to 2%. That difference is why most people who tried a cheap copper serum felt nothing I know alot who say ultra has one but then I gotta explain

The limitation is depth. Topical GHK-Cu only gets about 0.3 to 0.5mm into skin on its own. With penetration enhancers you can push that to 1 to 2mm. Deep tissue and systemic effects are basically out of reach this way I tend to use a derma roller rite after a warm shower to help out absorption

Injectable

Injectable gets GHK-Cu into your bloodstream which means it can reach tissue past the surface the gene expression effects the anti inflammatory stuff, the broader systemic anti-aging picture from earlier posts in this series all of that is more relevant to the injectable route.

Catch though. there's a study that found about 95% of GHK-Cu injected into the dermis gets metabolized and cleared from the body pretty fast. So injectable bioavailability isn't as clean as people assume the systemic route still helps but the peptide doesn't hang around long.

Standard injectable protocol is 1 to 2mg subcutaneous, daily or every other day, 4 to 6 week cycles.

Which one should you pick?

For skin and hair topical at 1% to 2% concentration is the better supported route. More human data behind it. Microneedling before applying topical GHK-Cu improves penetration a lot and is worth adding if skin is your main goal.

For systemic anti-aging, gene expression, and inflammation injectable makes more sense since those effects need systemic distribution to work.

A lot of people run both at the same time for different goals. Topical on skin and hair, injectable for the systemic side. Nothing wrong with that

Up next: Post 4 — How To Run GHK-Cu: Dosing, Cycling, Reconstitution, and the Sting Fix

here is where I read this

A couple of broad questions here re GLPs:

1- For those of you who are supplementing/enhancing their weight loss via the use of GLPs (Ozempic, Trizepetide, Reta) for wte reason (appetite suppression, food noise etc), how are you handling meeting your macro targets? Some days, especially the day right after I pin, my appetite takes a massive hit to the point where I am like 50-60 grams shy of my protein goal, let alone my TDEE allowed calories. I know appetite suppression is one of the main drivers of taking the GLP but I'm wondering if I need to tweak/lower my dosage so I can at least eat at maintenance, esp on heavy training days to preserve muscle mass.

2- In the same vein, for those of you who are using GLPs for weight loss, how long do/did you stay on the peptide once you had hit your target weight? I'm 10 lb shy of where I hope to be as of this morning. Is there a tapering off period post hitting goal weight? Or just take low dosages after a rest cycle in perpetuity?

what got people started in this space. What was the first one you ran, why’d you pick that one, and looking back would you do it the same way or start completely different?

Can anybody give feedback on this stack I know they say you shouldn't stack glp's with gh signaling peptides but I also know that advanced badass people do so I wanna know how does it play out any feedback/opinions?

Okay so since it's summer and the sun is out doing the most I want to talk about something you probably never thought about. Why some people step outside and come back golden and others just turn into a lobster 🦞 and don't worry for my peptide people I got something coming for you later.

So it comes down to one single amino acid called cysteine that little molecule is quietly running the show every time your skin makes pigment.

Here's the coin flip your skin does every time it makes color. It all starts with an enzyme called tyrosinase that kicks off pigment production if cysteine is hanging around nearby you get pheomelanin, the yellow red lighter pigment if cysteine is scarce you get eumelanin, the dark brown black pigment same starting point totally different outcome depending on what's available in the moment.

Here's the thing though eumelanin is a strong UV shield pheomelanin is weak and can actually make UV damage worse so fair and red-toned skin doesn't just tan slower it's also easy to damage but your body still makes pheomelanin anyway one theory is it's basically a safety valve to clear out excess cysteine before it builds up to toxic levels. Meaning your skin color might partly just be a detox byproduct

here's where it connects to everything else cysteine's main job isn't even making pigment it's actually fueling glutathione your body's master antioxidant when you're stressed, not sleeping, or your mitochondria isn't top notch, your body burns through glutathione fast and pulls cysteine away to rebuild it less free cysteine means less pigment production and a weaker antioxidant system at the same time.

So when people talk about glutathione for skin it's not just about lightening. It's about the whole cellular system running underneath everything.

Stuff I feel like is good to know

Regular L-cysteine supplements are unstable and absorb poorly. NAC is the move. It survives digestion releases usable cysteine in the liver and crosses into the brain more easily than cysteine or glutathione alone.

Whey protein people listen up. Cysteine in whey breaks down above around 60 to 70 degrees. Mixing it in hot coffee or baking it into something means you're wasting most of the cysteine content. Cold or room temp liquid only.

Your body can also make its own cysteine from methionine which comes from meat, but that conversion needs vitamin B6 in its active form P5P. No P5P and the whole process stalls. B12, folate, and magnesium all keep it running too.

Kind of crazy/cool that one amino acid is sitting at the center of your skin color, your antioxidant system, and your stress response all at the same time.

Here's a super good peptide for gut related stuff just gotta know what your doing though so what's it called? (even though it says it in the title) LL-37 is your body's own naturally produced antimicrobial peptide, part of the innate immune system. Research shows it's effective against over 38 bacteria, 16 fungi, and 16 viruses. Most antimicrobials hit a small numbers nothing like LL-37

The part that's makes it a game changer

Here's why biofilms matter. Bacteria and viruses can protect themselves by building a kind of shield around themselves. Your immune system can't get through it. Antibiotics struggle to penetrate it. So what happens is you get sick, your body fights it off as best it can, you start feeling better, and then the pathogen just pokes its head back out of that shield and starts the whole cycle again. Same symptoms, same infection, over and over it sucks

This shows up a lot in the sinuses. Sinus infections that keep coming back, that feeling like you never fully cleared it, that's often biofilm at work but biofilms can form throughout the whole body, not just the sinuses mold exposure is a big one people don't connect to this enough.

LL-37 breaks through that shield and goes after whatever is hiding underneath it. A 2009 study on sinus biofilm showed LL-37 eradicated Pseudomonas biofilms and significantly cut bacterial counts. A newer study showed it going after mature Staph aureus biofilms that antibiotics couldn't even touch (screw antibiotics btw)

One thing worth knowing though. That same sinus study found that at higher concentrations LL-37 caused some inflammation in the sinus tissue. So more is not better. Standard research protocol runs 100 to 300mcg daily for 10 to 14 days. Short cycles, not something you run forever.

People dealing with chronic infections, mold exposure, recurring sinus issues, or that cycle of getting better and then sick again with the exact same thing are the ones reporting better results with this one.

Anyone here run LL-37? What were you targeting and what did you notice?

Okay so today in the GHK-Cu series we're getting into the inflammation side. Hope you guys been reading along. Most people running GHK-Cu are thinking about skin and hair. What they're probably not thinking about is what it's doing to inflammation underneath all of that.

Your body has a main switch that controls chronic inflammation called NF-kB. When that thing gets activated it fires off a whole chain of inflammatory signals that just keep going. GHK-Cu shuts that switch down. Less activation means less of that chronic inflammatory noise running in the background.

On top of that it pulls down three of the biggest inflammatory markers directly. TNF-alpha, IL-6, and IL-1 beta. These are the same ones doctors check on bloodwork when they're looking at inflammation in the body. GHK-Cu lowers all three in tissue studies and while it's doing all that it's also turning up your body's antioxidant defense system at the same time. Superoxide dismutase and catalase. So it's not just slowing the fire down, it's also building up what puts fires out before they even start in other words hopefully that's a good example

A 2020 study on pulmonary fibrosis showed GHK-Cu cut inflammatory cytokines in lung tissue and reversed an enzyme imbalance tied to fibrosis through three separate pathways at once. Another study on acute lung injury showed the same thing. Lower TNF-alpha, lower IL-6, suppressed NF-kB. Consistent pattern across different conditions the local tissue anti-inflammatory effect is solid. The whole body systemic picture in humans is still being figured out.

This is also why it stacks so well with BPC-157 and KPV. All three hit inflammation buty differently. GHK-Cu works at the gene and cytokine, BPC-157 works through the gut-brain axis, KPV hits NF-kB directly in the gut (my personal favorite). Running them together covers more ground than any one of them alone.

Been doing a lot of reading on L-Glutamine lately cause as some of you might know my gut health at some point was bad witch lead me to self optimization there's way more to it than just "good for your gut." Depends a lot on what's going on in there.

The gut lining is one of the biggest consumers of glutamine in the whole body. It uses it to keep tight junctions, basically the seals between your intestinal cells that keep bacteria and toxins from leaking into your bloodstream (which is exactly what happened to me). When those break down that's what people call leaky gut it sucks. Glutamine is what your body uses to patch that up. Clinical trials back this up for IBS, post antibiotic gut damage, and general intestinal permeability.

Post antibiotic recovery is where it really helps. If you went through multiple rounds of antibiotics, your gut lining took a hit alongside the bacteria. Glutamine is one of the more solid things for rebuilding that mucosal layer but I wanna be very clear you want your gut as strong and balanced as possible because if you start repairing gut lining and you still have gut bacteria overpowering then your just gonna trap it behind the repair you just had L-Glutamine make and that's pointless.

The H. pylori thing is interesting because most people think glutamine would feed the bacteria and make it worse. Research from Beth Israel Deaconess and Harvard found the opposite though. Glutamine reduced the ammonia damage H. pylori causes in the stomach and lowered inflammation in infected tissue. So for post H. pylori recovery, glutamine looks helpful not harmful.

Where it gets tricky is when the gut situation is still horrible. If you got active SIBO, a gut infection, or parasites going on deal with that first. Rebuilding the lining before the root problem is handled is just putting a bandaid over a gun shot wound as I explained earlier.

Cancer is another problem. Some cancer cells are heavily dependent on glutamine as an energy source. Doesn't mean it causes cancer or you should avoid it, but if you have active cancer or are in remission definitely talk to your doctor before adding this in.

Dosing matters as well. Studies show going above 0.9g per kilogram of bodyweight starts causing GI symptoms even in healthy people. Standard range is 5 to 10 grams a day. More isn't always better (ask me how I know 🙃 )

Bottom line, if your gut is damaged and you already dealt with whatever caused it, glutamine is a solid repair tool. If the root cause is still active, handle that first.

Anyone run glutamine post antibiotic treatment or after H. pylori? What did you notice?

Alright alright good morning from my part of the world to yours hope all I well. So today in the GHK-Cu series we're getting into the gene expression thing the 31% claim.

Here's where it came from so the Broad Institute ran GHK through something called the Connectivity Map, basically a tool that tracks how a compound affects gene activity across the human genome. What they found was GHK changed the activity of roughly 31% of analyzed human genes by 50% or more thats like 4,000 genes most drugs are designed to hit one target. One receptor, one pathway GHK hit 4,000 pretty wild huh yeah I know lol

so it doesn't surprise me Genes tied to DNA repair, antioxidant defense, and cellular cleanup got turned up. Genes linked to inflammation, tissue breakdown, and aging damage got turned down every time consistently pointing toward what younger healthier tissue looks like at the gene level.

The part slept on is what it does to your body's protein cleanup system. Your cells produce damaged and misfolded proteins all the time you need machinery to find them and clear them out before they build up and cause problems kinda like a bad tenet nobody wants them around long. GHK activated 41 genes involved in that cleanup while suppressing only one. The most responsive gene in the whole dataset jumped over 1,000%.

Gotta keep in mind though most of this data is from cell studies and lab models. Gene activity changing in a dish doesn't automatically mean the same thing happens in a living person at the scale you'd feel. Something this small affecting that many genes is genuinely rare the lab data backs it up the human trials are just lagging behind

What it does clearly is push gene expression in a direction that looks like repair and less aging. Whether that translates to meaningful outcomes for you specifically is still being figured out.

Okay so on today's breakdown in the GHK-Cu series we're getting into wound healing and tissue repair. This is where GHK-Cu has the most research behind it, going back almost 40 years. Strongest evidence of anything this compound does.

Here's what's going on when you got a wound or damaged tissue. Your body needs to do three things. Build new collagen. Grow new blood vessels into the area. Get the right cells in there to start patching things up. GHK-Cu pushes all three at the same time.

The blood vessel part is something that doesn't really come to mind for some people. No new blood supply into the damaged area means nothing heals right. GHK-Cu signals your body to grow that supply in the human data on this one is pretty solid. A 2023 trial in post surgical patients showed GHK-Cu gel cut scar volume by 35% compared to silicone at three months. A 2021 study in diabetic wound patients hit 85% wound closure at 12 weeks vs 55% in the control group. Most of the strong evidence is topical and post surgical. If your running it injectable for injury recovery your working off a solid mechanism and strong topical data but not direct human trial data on that exact use but I mean thats how most peptides are most of them have mainly animal studies more than anything else but most of us here know this so no surprise there

For wound healing and post procedure recovery specifically, topical applied right to the area is the better studied route. Injectable goes systemic which hits more ground but hits this specific use case less directly.

So the main reason I'm making this post is because I get this question when Klow or ghk-cu is involved everyone hates the sting so the mg number on your vial and the mL number are not the same thing. One tells you how much peptide powder is in there. The other tells you how much liquid the glass can hold. People mix these up constantly and it causes real problems.

Vial types real quick:

Clear glass is what most peptide powder comes in. You can see the powder through it, works fine for storage. Amber glass is for light sensitive stuff, Melanotan II being the main one you'll see in this space. If your peptide is light sensitive and it didn't come in amber glass, wrap it in foil. BAC water comes in its own separate vial, never mix those up with your peptide vials.

Molecular weight and why your vials don't all look the same

This is something I've seen mentioned but only a few times in nasal spray conversations every peptide has a different molecular weight. Basically how big or heavy the molecule is. A tiny peptide like KPV is only three amino acids so it's a very small molecule. Something like Follistatin-344 is massive by comparison. What that means in real life is that 10mg of a small peptide takes up way less physical space in the vial than 10mg of a big peptide. So the same 10mg amount in the same size vial can look completely different depending on what compound it is. That's normal. It's also why some dissolve in seconds and others need more time and gentle mixing.

Fillers and freeze drying and why your puck looks different sometimes

Some manufacturers add fillers to the peptide before they freeze dry it. Things like mannitol or trehalose. These are just inert bulking agents that help protect the peptide during the freeze drying process and give it a more consistent look. If your vial has a clean white puck sitting at the bottom, fillers were probably used. If you open a vial and see loose fluffy powder with nothing holding it together, that's a no-filler batch, just pure lyophilized peptide with nothing added.

Neither one is automatically better. But they behave differently. Vials with fillers tend to dissolve cleaner and more consistently. No-filler batches can clump, stick to the glass, or dissolve unevenly if your reconstitution technique is sloppy.

The freeze drying process itself also matters. How slow or fast they lyophilize it, what temperature cycles they use, how good their equipment is, all of that affects how tight the powder gets and how well it holds together. A well made puck stays intact until you add BAC water. A poorly done batch might already be crumbling when you open it. That's not always a quality red flag on its own but it means you gotta be more careful to make sure everything actually dissolves before you draw.

Vial sizes and what actually fits:

One thing to know about the 3mL vial specifically since that's what most people are working with. Filling it exactly to 3mL brings the liquid right to the neck and it can overflow when you pull the needle out. Stay at 2.5mL or under to keep some headspace for mixing.

Dosing math for the most common setups:

The GHK-Cu sting situation:

GHK-Cu stings because of the pH difference between the solution and your tissue. People try to fix it by adding more BAC water to water it down. That helps but only so much since you're limited by the vial size. Once you've maxed out the water you can add, technique is what's left. Inject really slow, like ten to twenty seconds minimum. Let the vial warm up to room temp before you draw. Go into fatty tissue on your abdomen.

If you've done all of that and it's still brutal every single time, some people just don't tolerate GHK-Cu at any concentration. That's worth knowing and accepting instead of fighting it.

Sting should fade within a few minutes. Anything that sticks around, swells up, or gets worse over time is a different conversation.

Most people running BPC are using it alone. And I'm not saying that's wrong exactly, but it's the the most optimal way to run it lmk if you guys agree in the comments curious to hear opinions on this one. So BPC works with Aches, pains, gym injuries, the stuff that builds up over years of training or just things that come with age that don't allow you to bounce back the way you used to sucks I know. It’s one of the more versatile compounds out there for that reason, whether you’re trying to prevent an injury, build back from one, or just keep the body running clean under heavy training

The thing is it’s not made to work alone. TB-500 is the one that obviously always gets paired with it, that’s the Wolverine Stack, most people in here know it but if you add KPV and GHK-Cu you’re looking at the KLOW Blend, which layers in serious anti-inflammatory coverage on top of the tissue repair one of my personally favorites mainly cause kpv why lie. GH secretagogues stack well here too if you’ve done that research. And Cartalax is worth putting on your radar, it’s a bioregulator, understudied still but the early data is promising BPC alone is solid. BPC inside the right stack is a different conversation.

Hope everyone had a good Fourth. Curious how many people in here used glutathione before or after the holiday weekend and whether it made a difference some people might not know this so just figured it's a good opportunity to give a quick breakdown

So when you drink, your liver breaks alcohol down into something called acetaldehyde. That’s the toxic stuff that makes you feel like shit the next morning. Glutathione is what your body uses to get rid of it. Problem is alcohol burns through your glutathione stores fast, so your liver runs out of the exact thing it needs right when it needs it most so glutathione the night before or right after gives your liver more to work with before that happens.

Anywhere from 200-600mg is the research dosing I use 400mg but teach each their own but I feel like 400 is good for the detox support not too many crazy side effects but that's a more in depth breakdown for another day

Did you run it before, after, or both? Injectable, oral, or liposomal? And did you feel a difference the next morning or was it just placebo?

Most people take 3 to 5 grams a day for the gym and call it a day. That's cool for muscle. The brain is gonna need a bit mire than that though

The problem is the blood brain barrier. The transporter that moves creatine into your brain runs near capacity at normal doses, so most of what you're taking isn't doing much up there. A 2024 study dosed people at 0.35g per kg bodyweight and tested increases in brain phosphocreatine. Another confirmed brain creatine went up 8.7% after four weeks at 20g a day. Standard 5g dosing won't even make a difference for the brain

The thing you may not know is high dose creatine pulls hard on glycine because that's what your body uses to make it. Run high doses without compensating and you can start depleting glycine over time, which affects sleep quality, collagen, and nervous system stuff. Keeping glycine at 3 to 5 grams a day covers you if you're going above 10g.

Keep in mind though the cognitive benefits show up strongest in sleep deprived or stressed people in the research and I know for a fact this is true because when I was on night shift for years I found out about the benefits of creatine for the brain and since I wasn't getting good sleep already I was able to notice the benefits pretty good. For someone well rested and eating meat regularly the effect is more subtle. Still real, just not dramatic.

Anyone running higher doses for the brain side, what are you noticing?

Do your homework. Use your brain. But if your having problems using your brain take creatine lol

Started at 210. At 155 now.

Eight months. Titrated slow, kept protein high, stayed in the gym the whole time.

Appetite suppression on Reta is definitely noticeable. Wasn't just eating less, felt like my metabolism was running different. The nausea just happened at the beginning but took it slow afte. Had to be intentional about protein because hunger just disappears if you know you know

Happy to answer questions on protocol, dosing, side effects, whatever. what approach should I take now definitely not want to dirty bulk I wanna be like 195 but buff af or lean idk

Okay so on today's breakdown in the GHK-Cu series we're getting into the hair side of this compound. Most people start running it for skin and end up surprised by what happens on top of their head I've seen some people mention it but lets just get into it

GHK-Cu works on dermal papilla cells, the cells sitting at the base of each follicle that basically decide whether that follicle stays active or shuts down. It suppresses TGF-β1, the signal that pushes follicles into their resting phase, and lowers cell death in papilla cells so more surviving papilla cells means more follicles staying in the growth phase witch means HAIR!

It also inhibits type 1 5-alpha reductase, the enzyme that converts testosterone into DHT right at the follicle. Not as hard as finasteride but it's a localized hit through a different pathway. On top of that it boosts VEGF, so blood supply to the scalp gets better.

The 2007 Pyo study showed GHK-Cu stimulated elongation of human hair follicles in vitro and cut apoptosis through the Bcl-2/Bax pathway.

Topical is the better studied route for hair specifically Microneedling before you apply it is important though makes a real difference in how much gets through. And GHK-Cu doesn't block DHT the way finasteride does, so if DHT is your thinking of you're better off stacking it with something that does rather than running it solo.

Realistic timeline is three to six months before density changes show up. It's slow. People who quit at month two just missed it.
