I've had great luck with it - I take a combo of oral 5-amino and ATX when I'm not taking GH peptides.

I started it as I came off a round of CJC/IPA and KLOW because I wanted to focus on mitochondrial health and try a few of the exercise mimetics. I exercise 5+ times per week, lifting 4, HIIT, jump training, and a lot of walking/hiking. Improvements are subtle, but present: better recovery, stamina during exercise, and less overall soreness. Unlike SLU, which I seem to have a bit of a crash from, this just provides a little extra boost.
