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.

Mazdutide

Clinical programs have shown substantial reductions in body weight and improvements in cardiometabolic risk markers. It is a prominent newer dual agonist in the obesity literature.
