Probably 5-6 in a day was my max. I've tried most of the popular peptides at different doses and schedules, but the ones that actually moved things for me were Reta and TRT+. Everything else seemed pretty minor by comparison. Right now I'm testing injectable L-carnitine to see how it goes. I might go back to Tesamorelin and Ipamorelin at some point, but a lot of the others feel like hype with benefits too small to bother with.
It occurred to me that with the number of compounds some people run, this question should be asked out in the open. My highest was 7 shots in one day and I've sampled around 15 different compounds overall. It's getting to the point where it feels like a full protocol and I'm basically a regular at the sharps container place. So what's the most pins anyone else has done in a single day, and how many total compounds have you tried? No judgment, just curiosity from me and a couple friends who keep telling themselves one more small shot is fine.
