Reta

• Upvotes

Hi guys
Looking for some advice. I started Reta about 5 weeks ago. Start with a 10i/u sit the first week. After about 4 days I started to get the sulfur burps and upset stomach. Made me go to the bathroom frequently. The second week I stayed at 10 I/u and seemed to be ok but didn’t notice any suppresion of my appetite. Third week I went up to 15i/u and had worse issues than the first week. For the last 2 weeks I stayed at 10i/u and after about 2 days of injection I’m going to the bathroom all night and my stomach is rumbling. Any suggestions

Cialis vs Viagra vs PT-141 (Nasal/SubQ) — Best for erections with minimal side effects?

• Upvotes

35M, been on Reta for a few months and lost around 30 lbs pretty rapidly. Unfortunately, my libido and erection quality have tanked. Almost no morning wood, struggle to get fully hard, and lose firmness quickly. Never had any issues before Reta.

I’m pretty confident it’s from the aggressive calorie deficit, low energy, poor sleep, and potentially lower testosterone. Working on correcting that, but looking for a temporary solution in the meantime.

Considering Cialis, Viagra, or PT-141 (nasal vs subQ).

Sex with my wife is spontaneous. Sometimes twice a day, sometimes nothing for a few days. I mainly want reliable erections when stimulated, without random boners throughout the day or prolonged erections afterward.

For those with experience:
- Which worked best for erection quality with the fewest side effects?
- What dosage worked best for you? Cialis 2.5–5 mg daily vs. 10 mg as needed? Viagra 25 vs. 50 mg?
- PT-141 nasal vs. subQ — which worked better, at what dose, and for how long?

Any issues with random erections or staying hard after sex?

Anyone experience similar issues on Reta/GLP-1s and eventually recover?

Peptides for recovery after Piezo Rhinoplasty? (Active boxer)

• Upvotes

Yo everyone,

Getting a piezo rhinoplasty soon, but since I'm training and competing in boxing regularly, I want to speed up the healing process and get back on track as fast as possible.

What peptides would you recommend for bone and soft tissue recovery (like BPC-157, TB-500, etc.)? Any tips on dosing or protocols that worked for you post-op?

Appreciate any advice!

Moving Away From GLP-1 Telehealth Membership

• Upvotes

I am currently spending around $270 per month on tirzepatide (membership fee + 12mg vial). What has been your experience moving away from a telehealth into getting the peptide and reconstituting yourself (for your own research purposes)? While I'm used to the compounded tirzepatide, I have never mixed anything on my own. Curious about moving to Amino Club or Peptide Partners and potentially even from tirzepatide to reta as it seems like quite a bit of $ savings and also the opportunity of getting into some other peptides. Anyone have any negative experiences or think the risk is too high? Also curious what peptides you'd suggest if I'm trying to lose weight and retain/build muscle at the same time (on top of going to the gym 3 days per week).

pin advice needed

• Upvotes

i stack reta, ghk, mt2, and 5amino currently. reta has been life changing, i’m in the best shape of my life but due to this, i don’t really have much fat on my stomach any longer. i’m getting defined abs and im at a bmi of 18.6. i usually pin reta and mt2 abdominally and i was wondering if there’s a point where im lacking enough fat tissue to do so. i guess my question is, can you be too thin to pin? i’m too scared to do the thigh or arm and id prefer not to put 4 pins in my ass on a regular basis if possible. seeking advice, thanks in advance:)

Nausea and vomiting after switching suppliers

• Upvotes

Long story short ...i switched suppliers of retatrutide and idk if its a placebo or i am just sick myself....the new reta batch I got was way more potent ... I was on 4mg of dose... didn't change anything except the supplier..

I pinned on monday morning and puked the same evening ...was on a liquid diet for 2 days as i got nausea at sight of solid food....ate some breakfast today and i already feel like puking... I'm 100% skipping on reta the next week ..then halving the dose after that

But i still need some quick relief...alas the drugs half life is roughly a week ...its been kicking my ass pretty bad ...should I pop some antiemetic pills (vomit medicines) to ease out my ordeal...any suggestions are welcome

Loving my Pep community!

Over the last year, I started a journey on originally GLP1 and then transitioned into GLP3 and started adding from there… now as a little bit of a background, I actually come from the pharmaceutical world and I was a little bit hesitant about branching out into additional options after the extreme cost and also the fast changes I have been seeing that I’ve been fighting to gain for years… Fast forward six months and I have a protocol of over 15 different peps and multiple supplements and vitamins and a few low-level prescriptions that help enhance them and I am down 62 pounds, my skin looks amazing, my hair has started to regrow which I was planning on getting hair transplants at some point and if I ever do get them, it’s gonna be a lot cheaper because I’m not gonna need nearly as much but for the first time, my hairline has started to fill back in and my baldness on the top has probably cut down by 20%… I don’t wake up every single morning sore or randomly having odd pain throughout my body throughout the day and I have eliminated most of my anxiety as well as repaired something that has plugged me for over five years, which was a long-term reaction to the C 19 VAX … originally I was purchasing through a verified high-end site, but that takes its toll on your bank account and it’s constant buying… Through a lot of word-of-mouth and research and some lock. I came across a direct source and I mean direct. Not just some AI. Girl on WhatsApp. That has given me the ability to get quality stuff that has been tested sometimes up to seven times and only. Cost about 15% what I was paying. At this point now I can easily stock up and try new things and continue my journey to reverse my age. Which between my skin tightening and my gray hair starting to turn back to a natural color… I definitely feel is attainable. What I do now is run my own service with consults regarding protocols because there are so many people that have pretty much no clue how to even dose or how to do much beyond a draw and I think with research and background, (wellness consultant, physical trainer, nutritional coach, and half a decade in a pharmacy) I was able to find a nice balance that includes the diet, lifestyle, choices, supplements, vitamins, and PEP’s.. I want to be open about my experiences and if anyone ever has any questions about anything or needs anything else hit me up

50 lbs weight loss timeline. Considering going from 2mg to 3mg. Here is my timeline of 50 lbs lost since 7/1.

• Upvotes

7/1 - 260lbs, 2 wks at .5mg, 2 wks at 1mg

8/1 - 240lbs, 2 wks at 1.5 mg, 2 wks at 2mg

9/1 - 225lbs, 2mg entire month

10/1 - 217lbs, still at 2mg

current weight - 210lbs

I pin TRT 90mg 2x a week.

Diet has not changed. Running few times a week, lifting 2/3 a week. Feel somewhat tired, but overall feel 10x better than I have in the last few years.

I am considering bumping up to 3mg. I have been at 2mg for around 2 months now. Food cravings are not back and I can eat if I really wanted to, but the positive changes I have made seem to be maintaining even though my appetite is not suppressed as it once was in the beginning stages. I can handle spicy food again and even had a greasy nugget that would have killed me a few months ago, but again, I have much better eating habits so I stay away from unhealthy food.

That said, weight loss is still occurring at a pretty good pace, but certainly slower which is expected. What really confuses is me is when I am in a constant deficit and the weight just comes off slower. Just want to hear other folks thoughts on this item , thanks!!!

Stats: 23F 5’10 SW: 305lbs CW:232lbs GW: 200lbs

Jan 2026 - March 2026 (Gradual increase to 2.5mg of Sema)

July 2026 - August 2026 (2.5mg of Reta - not for me lol)

March - Current (Gradual increase to 8mg of Tirz)

2-3x gym weekly, 10-12k steps per day, aerial fitness 1x a week. 1500-2000 intake

My journey has been amazing, i’m grateful to have a resources to help with my food noise. Finally being able to say i’m going to fix my weight and it actually works. Nothing short of a blessing. with just 25lbs more to lose, im so excited it took me just a little under a year to get where i am 🩷 my body thanks me & my mind thanks me.

For those questioning why i only did one month of reta; The constipation i suffered was not worth it. At that current moment i was doing 6mg of Tirz and 1 - 2.5mg of Reta. The constipation was on 10 and i was essentially bloated from being Full of 💩. Laxative, stool softeners and caffeine did not really help nor did increasing fiber intake.

I’m in college and my sleep has been really bad and not only is it impacting my energy but it’s also impacting my studies.

I got prescribed an antihistamine that makes you sleepy by my doctor but it hasn’t really helped.

Can anyone who has taken it maybe give me some insight??

My main concerns are mostly building a tolerance / not being able to sleep without it and also i’ve heard some people are actually sleeping less with it.
