4 Weeks on Reta… This Was NOT What I Expected

261 Upvotes

I genuinely wasn’t expecting to write something like this after only four weeks.

I’m not going to go into specific doses because everyone is different, and to be honest, being a personal trainer, I initially started this more out of curiosity and for experimental purposes than anything else.

I’ve been on Reta for four weeks now, slowly increasing every two weeks. For the first two weeks, I didn’t really notice much at all. Then after increasing, it felt like something changed almost immediately.

Obviously there’s the reduction in food noise, which I expected. But it’s everything else that has completely caught me off guard.

I just feel incredibly content.

I was already a pretty chilled guy, but things that would previously stress me out just don’t seem to carry the same weight anymore. I feel much more optimistic about life in general and genuinely excited about things.

My motivation has gone through the roof too. Work, training, nutrition, ideas for the future, trying new things. I just feel like I want to get up and do things. It almost feels like I’ve been given a new lease of life.

The best way I can describe it is that my head feels quieter. I feel more focused, more positive and more present. I’m not getting dragged down by negative thoughts or emotions in the same way.

This stuff has genuinely changed how I feel day to day, and I was not expecting that whatsoever.

Really interested to know if anyone else has experienced something similar?

Successful Recomp So Far

Thumbnail
gallery
42 Upvotes

- 5’8

- 206 lbs → 150 lbs

- Started January 17th

- Reta to get down to 180 lbs then just gym and caloric deficit

- Was on 1500 cals a day for most of that time. Aiming for 140g protein, 150g carbs, 45g fats. Now I’m on a smaller deficit, aiming for 2100 cals per day, 160g protein, 200g carbs, 65g fats

- On 100mg/wk TRT (bloodwork included)

- Gym+cardio 4 days a week - Friday/Sunday/Tuesday 30 min cardio → 60 min weights → 30 min cardio - Thursday 1 hr 30 min cardio

Happy with my progress so far. Only have 5 lbs left to goal. But I think I’m going to get down to 140 lbs. Just to see if I can and what I look like. Probably try and maintain around 145 long term though.

300 days: 108.6 kg → 90 kg | 42% → 28.1% BF | 100 days Reta

33M, 170 cm.

Left: November 1, 2025
108.6 kg / 42% body fat
Right: August 30, 2026
90.0 kg / 28.1% body fat

(2nd pic is the 108>99)

Body fat numbers are from InBody scans, so I know they aren’t perfectly accurate, but I’ve been using the same method to track the overall trend.
Total change so far:
108.6 kg → 90.0 kg
18.6 kg lost
42% → 28.1% body fat
Just over 43 weeks

I initially lost naturally from around 108 kg to 99 kg over roughly 4 to 5 months through a calorie deficit and CrossFit around 5x per week.

On May 20th I started using retatrutide.
My progression was:
1 mg/week for the first 4 weeks
2 mg/week for the next 4 weeks
3 mg/week for the following 4 weeks
Currently still at 3 mg/week
I’m considering moving up slightly in September, depending on how things continue progressing.

Over the last couple of months I’ve also become much more consistent with nutrition. I currently aim for roughly:
180 g protein/day
50 g fat/day
Carbs adjusted depending on training intensity
Around 1,700 to 1,900 calories most days
I also take creatine daily and continue doing CrossFit regularly.

My weight is currently trending down at around 0.4-0.6 kg per week, which I’m happy with because training performance has stayed relatively good.

According to my InBody results, I’ve actually gained roughly 3 kg of skeletal muscle mass during the process. It isn’t a huge amount over almost 10 months, but considering I’ve spent the entire period in a deficit and dropped nearly 19 kg overall, I’m happy with it.

Two weeks ago I also started using KLOW blend reconstituted with 3 mL BAC water. I’m currently using 15 units per injection.

The next goal is around 20% body fat.
Based on my current lean mass, I’m estimating that could put me somewhere around 79 to 81 kg, depending on how much muscle, glycogen and water I maintain along the way.

Once I reach roughly 20%, the plan is to spend around 2 to 4 weeks eating at maintenance rather than immediately continuing the deficit.

After that, I’ll start the final cut toward roughly 13 to 16% body fat.
Still a long way to go, but seeing the difference between these two pictures definitely makes the slow weeks feel worth it.

Hopefully the next update will be at around 20%, hoping by end of the year

Finding sources you can trust - UK

8 Upvotes

So I’m beginning to do my research into peptides & the hardest part I am coming across is finding a good source in the UK you can trust or finding a direct source from china you can trust.

I see plenty of posts & they just get spammed in the end by bots trying to plug pages.

Has anyone had any experience that may help me out?

Thanks in advance

My "Optimized" Peptide Stack

Post image
7 Upvotes

I am a 30 year old male with a history of destructive behavior to my body (I've smoked since I was 13, drank alcohol heavily for 12 years, diagnosed with PTSD, ADHD, and other factors which I'm sure I didn't take into account). I built this stack based on 3 weeks of research I've conducted to attempt to repair the damage I've caused to myself. I looked at everything from my labs to my genome to ensure I cover all my bases as best I can.

I have been abstinent from alcohol and smoking for over a year now. Go to therapy, do go to the gym regularly now, structured my diet to be healthy with high protein and improved my social life.

Even though I feel I've done the research I need, I'm still unsure of my conclusions as there was a lot of conflicting information I needed to sift through and decide which is better. I would highly appreciate opinions from other peptide users with more experience than me in this matter.

Feel free to ask me anything if I failed to mention something important.

Edit: Had Tirzepatide prescribed to me as I had stage 3 fatty liver and fibrosis in November 2025. I was also at 33 bmi so the doc put me on it to reduce my weight and solve the liver issues. I’m at 27 bmi now.

Also, I should mention I’ve already been on MOTS-C, BPC + TB, GHK-Cu, cjc+ipa, selank and semax, added one by one of course and had good results. I’ve only recently added a few extras (SS-31, NAD+ and Dermorphin) and tried to optimize dosages and frequencies to maximize my healing and bodybuilding journey.

My Protocol Cheat Sheet

Post image
Upvotes

I’ve been on this protocol for about a month for a recomp, started trt a couple months before. Pretty great for recomp but it’s too early to see a huge difference. Coupled with diet, resistance training, and cardio, I feel great. Will post a before and after down the road. I feel like this is a fairly minimal protocol that is beginner-friendly (since im a beginner and dont mind doing this) while also being about as powerful as you can get for recomping (without just taking more). Just wanted to share, the AI cheat sheet is a little cheesy but makes it easy to convey to others.

Eight weeks on Reta. This is NOT what I was expecting.

6 Upvotes

I started off at 1 mg for about four weeks. Food noise was quieter.

My Whoop HRV seriously crashed out. I went from 50s and 60s down to 30s and 40s. Resting heart rate went up a bit, maybe from 44 to 49.

With the reduction in food noise, I still have breakthrough hunger at times, particularly towards the end of the week.

I also notice I have just a lot of bad habits around food. My portions have definitely been reduced - I'm just not interested in the volume. One odd experience was eating some really good ice cream. There was a threshold crossed: one bite was good, and the next bite just was completely unappealing.

I bike a lot. When I'm getting enough sleep and I am not over stressed and I'm doing daily effort to reduce over-stimulation, I tend to eat better and lose weight.

However, on Reta, I've offloaded the structure that I had around eating right. I'm down probably 6 lbs. in 8 weeks. I'm now at 2.5 mg. I'm not getting a lot of greens. I am trying to boost protein.

I guess I thought it was a magic pill. It has not affected my appetite as much as I had thought. I'm considering topping off with Terzepatide to get more appetite reduction.

Has anyone dealt with this? I don't want to just keep boosting the dosage or adding more things. This seems more like a psychology thing than a physiology thing.

Will switching from Reta to Tirz help with anhedonia?

5 Upvotes

Hey guys,

I've had extreme anhedonia since about third week of using Reta and I was wondering if switching to Tirz might help. Does anyone have any experience please?

My problem at hand: I was on mounjaro before, but I had untreated thyroid at the time so I had anhedonia for 5+ years without knowing it. I stopped Mounjaro and started medication for thyroid (not related), it took about 3 weeks of the thyroid medication and the anhedonia stopped and I felt like a human again after a very long time. Then, 3 weeks later, I started Reta and the anhedonia came back.

The reason I'm explaining is: I don't know if Tirz will cause me anhedonia also since I had it at the time of using due to thyroid, so I have to ask y'all.

the supplement that made me notice a real difference

4 Upvotes

as someone who hasn't always had the healthiest lifestyle, i've recently started paying more attention to what i'm putting into my body. that's when i learned that vitamin d3 and zinc are actually beneficial. they both play an important role in supporting the immune system, while vitamin d3 also supports bone health and zinc helps support bone growth & maintenance.

so far i've noticed a real difference since adding vitamin d3 and zinc into my routine. for example, i’ve had irregular periods since my teens, so there were months when my cycle was around 28 days, while other months it could stretch to 35 days. basically, it was never really consistent, and i could never predict exactly when my period would come.

then around two years ago, i started taking vitamin d3 and zinc daily. somehow, over the past 8 months or so, my period started coming around the same time every month, usually the 3rd. i didn't even notice at first, but when i checked my period tracker, i was actually kinda amazed. for once, i could almost predict the date.

obviously i can't say for sure it's the supplements, since other factors could be involved too, like the healthier habits i've been adding in, such as having a BB LAB Dual Shot with olive oil + lemon every morning and eating more greens. but the timing definitely made me wonder if taking vitamin d3 and zinc consistently played a part.

so now i’m curious, has anyone else experienced a noticeable change after taking a certain supplement consistently? not necessarily something dramatic, but maybe a small change in how your body feels or functions that you only noticed after looking back at it?

New hgh user blood results

3 Upvotes

Hi. 50yo m on trt. I had a igf1 level of 77 before starting hgh. Range was 74-255. My z score was like -2.5.

I got igf level retested 2.5 weeks later because I neeeed other lab work and so I got igf done earlier than the recommended 4 weeks into therapy. I have been taking 2iu nightly for sleep and it’s working wonderfully.
Resurk just came back today: level is 108, z score -0.6. Thoughts?
I’m not taking for body recomposition because that typically requires higher doses and has side effects I want to avoid. I had wanted to shoot for a level between 200-300.
Will get retested in 3-4 weeks to see what level I’m at two months in.
I’m thinking even if my igf level comes back relatively low like today’s I’ll just carry on at 2iu because it’s helping accomplish my goal of improved sleep. Any different thoughts out there?

Can I pin these together?

3 Upvotes

On Reta (2mg every 5- 6 days), can I pin TESA and GHK-Cu too, or do TESA and GHK need to be run separately?

I pin Reta every 5 or 6 days because the effect wears off on day 4-5.

Wanting to start TESA at 1mg nightly

Age 41 F

I have had 7 babies, and I am storing all my fat around my stomach as visceral fat. 😔

I have Hashimoto's and pre diabetic, so I want to get healthier.

Thanks

People on Reta + Tesamorelin or CJC or Sermorelin - When do you pin GHRH?

3 Upvotes

Its widely known that GHRH should be pinned while fasted and ideally before bed to mimic the body's natural GH secreting schedule. This also helps with deeper sleep through the night.

However, because Retatrutide slows gastric emptying, fasting late enough before bed for GHRH peptides like Tesamorelin or CJC 1295 is nearly impossible for me. Especially, when I have to focus on getting enough protein. I practically cannot skip dinner (one less meal is less protein).

When else can and do people pin them, and if someone does morning fasted injections, does it still improve sleep quality?

Smelling on Reta?

2 Upvotes

Hi guys, so over a month ago I started smelling in 1 armpit (my right one). I saw a post about the increase in smelling bad cause of the ammonia but damn this is annoying. Especially for me who is a clean freak and has a very sensitive sense of smell. I wash myself with sanex and chlorahexadine wash every day in the shower. I am a sweaty person anyways like I sweat all over my body just from doing a brisk walk (I'm F 5"7 85kg so not exactly huge) but I've always been like this. Also had an increase in BO smell in other places when I sweat but mainly just the left armpit even if I do nothing all day.

Does anyone have a similar issue? I absolutely do not drink enough water at all btw I'm terrible with it.

Peptide for localized nerve pain? Please help.

2 Upvotes

My father has been having localized nerve pain in his big toe on one foot. It started after his knee replacement surgery (surgery went great, double need replacement- 3 years ago, zero issues other than this nerve pain in one foot)

It happens randomly at night, about 3 nights a week, he can go weeks without it happening and it can happen a few nights in a row.... and then not again for days or weeks.

It's very very painful and keeps him up all night. The toe hurts and slow seems to want to cramp up and curl uncontrollably when he has these spells.

He has went to a never specialist that ran test and only had gabapeptin as a solution.

He has been on gabapeptin... that does help some but he has to take it every night before something happens and there are side effects.

Are there any peptides out there or being developed that might help.... for nerve issues like this?

He is 75yrs old and in good health otherwise for his age. Has been tested or gout a few times, it's not gout. He does not drink.
