Fragment 176-191 vs AOD-9604

HGH Fragment 176-191 and AOD-9604 are closely related — AOD-9604 is essentially a modified version of this fragment with a tyrosine added for stability. Both aim to isolate growth hormone's fat-burning effect by using only the C-terminal region believed responsible for lipolysis.

The strategy is elegant in principle: keep the fat-mobilization signal, drop the IGF-1-mediated growth and insulin-antagonizing effects of full HGH. In practice, clinical evidence for meaningful fat loss remains limited for both. Members researching lipolytic fragments often compare the two in the thread below.
