HGH Fragment 176-191 10mg

HGH Fragment 176–191 is a peptide derived from the C-terminal region of human growth hormone (hGH), corresponding to the amino acid sequence YLRIVQCRSVEGSCGF. Unlike full-length hGH, this fragment has been studied primarily for its lipolytic activity (fat metabolism modulation) and is not associated with insulin signaling or somatic growth effects.

It is often confused with AOD9604; however, HGH Fragment 176–191 is a distinct, non-modified sequence and lacks comparable clinical development data.


Key Scientific Points on HGH Fragment 176–191

Structure and Function

HGH Fragment 176–191 is a 16–amino acid sequence (residues 176–191) of hGH. Experimental research has explored its ability to modulate adipose tissue metabolism, reflecting the fat-regulatory domain of native growth hormone without activating growth-promoting pathways.

Distinction from AOD9604

Although frequently mentioned together, HGH Fragment 176–191 differs structurally and developmentally from AOD9604, which is a modified analog designed to improve stability and has undergone limited clinical investigation. The unmodified fragment does not share the same clinical safety or efficacy data as AOD9604.

Research Applications

Preclinical studies have investigated HGH Fragment 176–191 in experimental oncology and drug-delivery models, including research suggesting that it may enhance the cytotoxicity of certain chemotherapeutic nanoparticle formulations (e.g., doxorubicin-loaded nanoparticles) against MCF-7 breast cancer cells.

Lack of Human Clinical Data

Public scientific sources, including review literature, emphasize that HGH Fragment 176–191 has not been extensively studied in humans, in contrast to its modified analog AOD9604. As such, its pharmacokinetics, safety profile, and long-term effects in humans remain unknown.
