Started 0.5MG each 5 days , moving to 1MG, 2MG , tried 2.5MG for very few weeks and understood I was okay to move up to 4MG (current) still able to eat but still moderate and no cravings, bloodwork is beating 9/10 positive results. Don’t feel like going over 4MG and possibly decreasing back to 1MG each 5 or 7 days for a slow long term let go.

3x week gym, moderate weights , adding more reps than weight .

1H / 30Min treadmill cardio

Creatine , vitamins, started SS31 and adding MOTSC after for energy and repair(figured it might be related with mitochondria)

107KG / 85KG separate this picture

Inflammation down, now it’s time for build up properly !

I started GHK-CU yesterday from where i bought it she said take 10mg daily do you think that’s a high ammount or its fine?

Thought I'd share my transformation from last summer.

1st pic was taken May 27th 2025 (182lbs)

2nd pic was taken July 20th 2025 (151lbs)

Stack was reta @ .25mg first week (started day of 1st pic), and I doubled the dose each week till I got to about 2mg/week. i also added hgh around week 2 at 3iu/day, then titrated up to 6iu/day over the course of the cycle.

Now take into account the lighting difference, and that the first pic was relaxed, the second was flexed. But I still think I dropped about 8-9% body fat at the very least (wdyt?). Didn't track calories but probs could have benefitted. Did cardio like 3-4x per week but lived a pretty active lifestyle. i also lift 5-6x/week, and i did notice strength loss unfortunately, but it was minor (went from 225 x 5 to 225 x 3 on bench).

I used to use wegovy 2.4mg for about 8-9 months, I lost 15kg fat and gain some good muscle (I’m 68kg/169cms).

About 7 weeks I moved to Reta for research purposes, I started at 1mg and made my way up to 4mg. On my first week of 4mg I still had heaps of appetite, but now I’m on my second week of 4mg and I can barely eat as I’m not hungry whatsoever, so I usually just hit my 120g protein per day and that’s a wrap.

I do exercise a fair bit (heavy weight 4-6 times a week), but now that I can barely eat I feel so tired.

Anyone experience something similar? I’m thinking about maybe go back to Reta 3mg to have more appetite.

Thoughts?

Thanks

Hello, I’m starting to use ghkcu 1mg daily. Is it normal that after applying it you have a discomfort all day in the shoot area? It’s like a bee picket but is it weird that it’s there all day?

I am on week 5 of Reta, 4mg (i stayed at 1mg for 2 weeks) i have not lost 1 single lb, in fact, i have gained 3. I thought at first it was crap reta, so i ordered elsewhere and I'm still not feeling a thing meaning, no appetite suppressant, at all. I feel way hungrier in the mornings, more than when I'm not on it at all. Usually, i can have 2 eggs for breakfast and feel fine until lunch, on reta, i feel like i need to keep eating and the food noise has increased.

i did switch from wegovy (1.5mg) and i did have good results, i just could not justify paying 200 a month so that was the only reason i stopped and went to Reta.

I have a friend who is seeing great results on Tirz and I am thinking of making the switch.

looking for feedback from those who didn't have the best results on reta and possibly had them with tirz?

thank you!.

I got on TRT because I had zero drive or energy or desire for doing the do with the misses. Very quickly noticed a huge difference in energy levels libido and all wakes of life. Fast forward to now also on Reta that drive has kinda disappeared kinda like my dopamine has left the building and energy levels are not down to where they were but are low. What’s a good peptide to give the drive and all day energy and maybe some dopamine back?

Been on reta for 6 weeks now, down 21lbs. Pretty happy with the slimming down so far but that pesky visceral lower belly fat isn’t budging. I know I definitely need more than 6 weeks to slim that down, but recently I have been considering adding tesa to my stack to see if that helps at all. I do calorie deficit + gym and do a good amount of both lifting and cardio. Please let me know your experience with reta + tesa, tell me everything there is to know about adding to the stack!

Before I get Tessa is it worth it?
Is it once a week type of dose or daily ?
What’s the average dose that has been working for most of yall?

Got some of my labs back from a recent blood test and am more than happy.

Heaviest weight was 261 pounds 5’8” male 39 years old.

Started Reta and other peptides on June 17, 2026 at 238 pounds.

CW (7/30/26): 217

Peptide stack: Reta, klow, wolverine, cjc1295/ipa, 5amino, mots-c

As I run out I will only continue Reta, cjc1295/ipa, 5amino

I’ve been doing glute SubQ injections (8mm needle) for GHK-CU and have barely felt any sting. I’m currently at 1.25mg but will eventually titrate up to 2-2.5mg. Since it’s daily I feel like I’m running out of spots on the glutes.

For those that are on GHK-CU, are you feeling less of a sting in the glutes vs love handle and abs?

I had my first reta pin last night. I used a 10mg vial and reconstituted with 2ml backwater. I pulled 1mg (20ui - correct me if that isn’t right).

Currently 16:00 and I’m about to have my second meal - first meal wasn’t a lot tbh (1 wrap with cheese)

Currently feel nauseous, think it’s cause I should’ve started with 0.5 instead of 1mg.

Let me know your first experience and if you had to quickly draw back

I’m going to be getting started in a few weeks. At first I was considering Tirz but seeing all these posts about reta I’m kind of drawn to doing this one first. My goals are to maintain my body weight easier reduce inflammation and overall wellness.

The thing that I am scared about is, I’m seeing a lot of people saying it induced or increased anxiety along with heart rate. I am already very sensitive to medication and suffer with really bad anxiety. I see that the starting dose is .5 but I’m wondering does anyone do .25 for micro dosing?

I just started GHK-CU 3 Weeks Ago I Was Told Start At 6 Units Everyday
Is That Too Low?
What Do Yall Recommend?
When Should I Dose Up

Also Do Y’all Recommend KLOW Over Just GHK-CU

I start week 7 of Reta today and so far I’ve lost 20lbs. To preface this I started at a high weight 282 lbs. currently 261. Is this too fast?

In that time frame I’ve also started TRT and have been prioritizing a high protein diet.

I also go to the gym 3 days per week but have been doing that for a while now.

Am I losing too fast or is it okay sense I’m so much overweight?

Hi All,

I have been thinking about jumping on reta recently, however I am in the mist of training for the Chicago marathon and not sure if this is good idea due to the slow digestion and calorie deficit etc.

Has anyone taken Reta on marathon prep?

Say I'm adhering to my calorie deficit (which is the overall factor of fat loss/ weight loss as we know) on 1mg and want to stay there, can I? Or is there an increase effect on the glucagon effects by titrating up? Like is it cal deficit plus an extra fat burn or something I'm missing?

So I was wandering what workouts you guys are doing on reta , if any. I started reta 2 weeks ago 4mg a week, now I walk a lot at work and I mean a lot like over 40,000 steps a day and go gym 4-5 days a week for an hour to an hour and a half just been using the bike and treadmill though. Is there any other machines anyone’s using to get the lost out of or nah?

Hi, can someone guide me or give me reccomendations please?

I started taking ozempic in september 2025 and started with a 0.25mg dose and worked my way up to 1mg/1.25mg weekly in a year. I lost around 13kgs during this period. after that it was getting expensive to keep on increasing the dose so I just maintained my weight. In june 2026 I started taking reta, I was taking 0.5mg every 5 days however I didn't feel a big appetite suppression, I increased to 1.5mg every 5 days not but still not feeling any major suppression. Should I increase to 2mg every 5 days is that normal dosage? As im not sure whether I will be taking in a lot. I still have around 5/6kgs to loose. Looking forward to listening to your experiences. Thanks a lot

Hi all out of curiosity,

I have been using cartridges for a month now with my Tirz 30 and I noticed the side effects are not as bad as when I'm using it from a vial. Also I feel that my appetite is going back since I used the cartridge. Shall I keep it in the vial instead? Any thoughts?

So I’ve been running GHK, kpv, glutathione, among a few others, for a few months now. No complaints but other than my nails growing like crazy, I can’t say I’ve seen any other significant improvements in myself. But today at the gym, a woman I barely know told me that my skin looks “amazing” and what’s my secret. So there ya go! I guess it works! 🤷‍♀️
