Product Overview

HGH Fragment 176-191 is a stabilized analogue of the C-terminal region of human growth hormone (hGH) comprising amino acids 176 to 191. This 16-amino-acid fragment contains the helical structure responsible for hGH's lipolytic activity while excluding the domains that mediate insulin-like effects, IGF-1 stimulation, and cell proliferation. Originally discovered at Monash University in Melbourne, Australia by Professor Geoffrey Norstedt's group, the fragment was found to retain up to 12.5 times the lipolytic potency of full-length hGH while specifically targeting adipocytes without the metabolic side effects associated with exogenous GH administration. This selectivity makes it one of the most-studied peptides for fat metabolism research.

MS confirmed 176-191 fragment, no truncation, purity ran 98.5

Reliable supplier for fragment work

We're particular about fragment integrity since incomplete sequences ruin the experiment. 22EXO's QC has been consistent across two orders. Cake was uniform, MS clean.
