Noob questions - Reta

Hi all! I’m 34f. Stuck at weight 78kg with calorie deficit, daily steps and strength training 3 times a week. Goal is 65kg. I have some hormonal and inflammation issues probably feeding into this, adhd (unmedicated) and hypermobility. I’ve got some 10mg Reta - peptides calculator says to mix with 4mg. I can either take 1iu (.25) or 2iu (.5) to start.

Chatter seems to be mixed around starting doses, so thought I’d ask here! For context, I tried mounjaro last year when I was 84kg but had to stop after 3 weeks on 2.5 due to suspected gallbladder pain. It worked for me - I lost weight and inflammation pain was less, but I’m not wanting to risk my overall physical health. I’m assuming I’m quite sensitive to this type of drug.

As a side, I’ve also got semax (spray version) which is helping massively with cognition and selank spray which I haven’t yet tried as I’m trialling the semax first so I can be sure which peptide is doing what.

Any help gratefully received!
