Description
HGH Frag 176–191 is a synthetic peptide fragment representing amino acids 176–191 of the human growth hormone (HGH) sequence.
This truncated analog retains the lipolytic (fat-burning) domain of HGH but lacks the growth-promoting and diabetogenic activities associated with the full hormone.
Research indicates that HGH Frag 176–191 acts by stimulating lipolysis and inhibiting lipogenesis, particularly in adipose tissue.
It is believed to work through β-adrenergic-independent mechanisms, modulating the activity of adenylyl cyclase and cAMP-dependent signaling pathways, resulting in enhanced fat metabolism and energy mobilization.
Because it mimics HGH’s metabolic benefits without significant IGF-1 elevation or mitogenic activity, HGH Frag 176–191 is an important model for studying targeted fat metabolism, peptide-based hormone selectivity, and metabolic regulation.
