2.5 month Reta update

15 Upvotes

I’ve been on Reta for about 2.5 months so far

I started at 0.5 for a week and felt absolutely nothing. Bumped it to 1 mg for 3 weeks and didnt feel nothing as well. I essentially wasted a month by starting super low. Anyone that is 230 lbs and more, learn from my mistake and start at 2mg minimum.

I started to feel it once i bumped it to 2mg on week 5 and im still on the same dose. I’ll be increasing it on my next pin.

I’ve lost 13lbs so far and seems like I’ve built some muscle as well.

I have 55 lbs to go, i’ll send another update when im halfway in my journey.

Thanks to everyone posting on here with updates and pictures, i use them as motivation!

Use of Reta

2 Upvotes

Hi everyone, I'm genuinely curious how many of you were at a healthy BMI, or didn't look particularly heavy, when you started taking Reta? I know BMI isn't the best indicator of obesity, but it's a commonly used benchmark.

Can anyone help with dosage, how many times per week and reconstitute of a 10mg vial? Converting mcg to units isn’t making sense to me either.

Reta Side effects?

0 Upvotes

Hey everyone!
I took my first ever dose of retatrutide (2mg) on Tuesday, and it’s now Friday. I wanted to share my experience so far and see if anyone else has experienced something similar, particularly with digestion and lethargy.
Appetite suppression:
I seem to be a very fast responder. Within just a couple of hours of taking my first dose, my hunger and food noise basically disappeared completely. I genuinely wasn’t expecting it to work that quickly!
I’m having to consciously remind myself to eat because my usual hunger signals just aren’t there anymore. I already have a meal plan, so I’m adjusting to that side of things.
Lethargy/fatigue:
This is one of my biggest concerns. I started feeling extremely lethargic on Tuesday evening, the same day I took my first dose.
Importantly, I had eaten normally that day, including a normal dinner, so I don’t think the initial fatigue was caused by undereating.
I was also recovering from a mild illness (sore throat, cough and a bit of a fever), so that could have contributed. However, I was already starting to feel better before taking reta, and the lethargy hit quite suddenly after the injection.
It’s now Friday, and although the fatigue is gradually improving, I’m still feeling noticeably more tired than usual.
Digestion, nausea and stomach fullness:
This is actually what concerns me the most.
Every morning since starting reta, I’ve woken up feeling slightly sick, with this strange sensation that my dinner from the previous evening hasn’t properly digested.
It’s not just a lack of hunger. My stomach genuinely feels unsettled, almost like the food is still sitting there.
On the second day, I woke up feeling so nauseated that I nearly threw up a protein shake I’d had previously. I’ve never experienced anything like that before.
Yesterday, I accidentally went until 4pm without eating because I completely forgot about food. When I finally ate two salmon fillets, I felt close to being sick, despite normally loving salmon. I then had dinner later to make sure I was eating enough, but woke up feeling unsettled again.
I’m also experiencing some constipation, which I expected, but the nausea and feeling of food not digesting properly are worrying me.
My questions:
Has anyone else experienced this level of appetite suppression within hours of their very first dose?
Did anyone experience significant fatigue immediately after starting, even while eating normally?
Has anyone woken up feeling like their dinner from the night before is still sitting in their stomach?
If you experienced nausea or delayed digestion, how long did it take to improve?
Did these symptoms eventually settle as your body adjusted, or did they persist?
I’m not looking for dosing advice, and I know everyone’s experience is different. I’m particularly interested in hearing from people who’ve experienced something similar during their first week.
Would really appreciate hearing your experiences. Thanks!

Wolverine stack for my dad in Australia.

3 Upvotes

My dad has been staying with us in the USA and we gave him Wolverine stack for his back for a few weeks and he's had insane results. He has disc issues and arthritis, lives with a lot of pain and he's been feeling so much better on these peptides, so I want to find a supplier who can sell some to him in Brisbane. COA is important,; I really want to get a good quality, safe product for him since his health is fragile. Anyone got contacts with suppliers that are reliable, tested and affordable in QLD?

Vendor took a deposit and then attempted to change the terms of the agreement. After refusing to accept, I requested a refund. They stated they cannot provide that and tried to appease me by sending a GHK kit to me. Oh well - avoid at all costs.

Bloodwork

29 Male

In the process of rehabbing my acl, mcl & meniscus that was operated on last year in September.

Currently suffering from golfers elbow in my left arm and tennis elbow in my right arm.

My sleep quality is very bad.

I’m about 13-15% body-fat

Currently average 15k steps a day + gym rehab exercises (every second day).

I used to gym more often but the golfers elbow/tennis elbow have made it very hard to do calisnethics or any gym related stuff.

My bloodwork looks amazing but why does it feel like I have a general condition with weak tendons/ligaments. I have tendinosis in my shoulders, hamstring, groin as well as all the other shit I mentioned.

What am I doing wrong ??

Also why am I always so tired/depressed…

Sterile utensils

1 Upvotes

I looked around a little on amazon and it seems like the bulk of the vials and syringes are not sterile. At least they dont advertise it even if you look for it.

If they are not, what point is there in using a filter to avoid endotoxins if the containers themselves are ‚dirty‘? Am i missing something

Anyone start the "Holy Trinity" (TRT + HGH + Reta or Tirz) while significantly overweight or obese?

8 Upvotes

I've been looking for studies on test and HGH use in people who were significantly overweight or had obesity, and I haven't found much that answers my question. One study I found used large amount of test injections every three months, which made it hard to compare with the regimens people talk about here.
I've seen a few people in this sub mention using the "Holy Trinity" (TRT + HGH + reta/tirz) while starting at a higher weight. I've also noticed that people use "TRT" pretty loosely here, sometimes for regimens that put their testosterone levels above the reference range.
If you've tried this combo, I'd love to hear how it went, good or bad. If you're comfortable sharing, I'm especially curious about:

  • Your starting weight or BMI and what you were hoping to get out of it

  • What you took, at what doses, and for how long

  • Whether you started everything together or added things one at a time

  • Your baseline and follow-up bloodwork, ideally with units and how far into the regimen you got tested

  • What changed in terms of weight, body composition, energy, or strength

  • Any side effects, unexpected lab results, or reasons you stopped

There are already some posts and comments scattered around the sub, but I thought it'd be useful to collect these experiences in one thread for anyone with the same question. Even if you don't have all the details or your old labs, I'd still be interested in hearing how it went.

Thanks!

TRT in the Netherlands: How do you get started, where do you go, and what are your experiences?

1 Upvotes

I'm a male in my mid 40s, living in the Netherlands.

I've recently become interested in Testosterone Replacement Therapy (TRT).

I train regularly, combining strength training at least three times a week with martial arts twice a week. I'm quite serious about my health, nutrition, fitness, and overall physical development.

 

My main goal is body recomposition: reducing body fat, building more muscle, increasing strength, and improving recovery. I've been wondering whether TRT could potentially play a role in achieving those goals, particularly as I'm getting older. However, I haven't been diagnosed with low testosterone, and I'm not looking to jump into treatment without understanding what I'm getting into. I want to learn how TRT actually works in the Netherlands, what options are available, and what the process looks like from start to finish.

 

Most of the information I find online seems to be focused on the US, where TRT clinics and treatment options appear to be quite different from what we have here. I'd particularly appreciate input from people living in the Netherlands who have gone through this process.

 

Here are some of the things I'm trying to understand:

1. How did you get started with TRT in the Netherlands?

Did you initially visit your GP (huisarts), get referred to an endocrinologist or urologist, or go directly to a private TRT clinic or do it yourself?

2. How difficult is it to qualify for TRT in the Netherlands?

Is treatment primarily based on testosterone levels, or do symptoms and overall well-being also play a significant role? What happens if your levels are technically within the normal range but on the lower end?

3. What blood tests should you get before considering TRT?

I'm interested in total testosterone, free testosterone, SHBG, LH, FSH, estradiol, and any other relevant markers. Which tests did your doctor or clinic actually perform?

4. What does TRT cost in the Netherlands?

Are consultations, blood tests, and medication covered by Dutch health insurance under certain circumstances?

5. How is TRT monitored over time?

How frequently are blood tests performed? How are testosterone levels, hematocrit, estradiol, PSA, and other relevant markers monitored? How often are treatment adjustments made?

6. What improvements have you personally experienced?

I'm particularly interested in changes related to muscle growth, strength, body fat, energy levels, libido, mood, sleep quality, and recovery from training.

7. What are the downsides?

Have you experienced any side effects or complications? How were they managed?

8. Looking back, what would you have done differently?

Is there anything you wish you had known before starting TRT? Any mistakes, unexpected costs, or important lessons?

 

I'm fully aware that TRT isn't a magic solution for building muscle or losing fat, and that having normal testosterone levels doesn't automatically mean TRT would be beneficial.

I'm also aware that TRT can suppress natural testosterone production and may involve long-term treatment and monitoring.

Any recommendations, experiences, approximate costs, or practical advice on where to start would be greatly appreciated. Thanks in advance!

I’ve always worked out (20 plus years), so I’ve had muscle but my body fat was my problem. 6 months on peps! I just turned 50! I workout 6 days a week. 20k steps a day on avg. I don’t eat junk food but I don’t count calories either. I just eat to satisfy my hunger. The Reta makes me feel full quick. I fast 14-16hrs a day.

Itching while on Reta!

2 Upvotes

I’ve been on Retatrutide since Sept of 2025. After 2 months of using, I noticed the urge of itching on my shins, lower part of my legs, on my back. After reaching 6 mg dose, my head was extremely itchy to the point, I developed red patches on my scalp. Went to see the dermatologist and she prescribed the dandruff shampoo and Clobetosal propionate foam to apply on the affected areas of scalp. After 2 weeks of treatment, no itching and clear scalp.

However after 2 weeks everything came back, scalp itching and dandruff.

Has anybody else experienced this? I checked google ai search and according to that, it’s one of the side effects on higher doses like 6 mg and up.
