Research Overview
HGH Fragment 176-191
This 16-amino-acid fragment specifically targets adipose tissue via beta-3 adrenergic receptors. Works through a GH-receptor-independent pathway, explaining selective fat-loss properties without growth-promoting effects.
L-692,429
L-692,429 was important in early GH secretagogue research because it showed that nonpeptide molecules could trigger robust GH release. It remains a classic tool compound for studying receptor-mediated GH pulsatility and appetite signaling.
