Research grey

This compound sits in research-grey territory. The caveats below carry more weight than for FDA-approved entries — read them.

Mechanism

Functionally similar to AOD-9604 (a Tyr-modified version). Marketing claim is 'all the fat-loss of GH without IGF-1 elevation' — preclinical evidence partial; rigorous human RCTs minimal.

Specifics
Weight / fat lossBody composition (lean mass)
Caveats

Functionally redundant with AOD-9604 in stack design. Most consumer claims trace to a small set of preclinical studies. Identity verification poor in grey market.
