HGH Fragment 176–191 — 5 mg

99.2% Purity
$59.99per 5 mg · lyophilized

HGH Fragment 176–191 is a 16-amino acid synthetic peptide corresponding to residues 176–191 of full-length human growth hormone. It possesses the helical fat-metabolizing region of hGH while lacking the receptor-binding N-terminal domain responsible for anabolic and IGF-1-stimulating activity. Research has characterized its selective stimulation of lipolysis in adipocytes through β-adrenergic signaling without affecting glucose metabolism or inducing insulin resistance. For research use only — not for human consumption.

Independent Verification

Third-Party Tested. Every Lot.

Every batch of FRAG 176-191 undergoes independent HPLC and mass spectrometry analysis through an accredited third-party laboratory before it is released for sale. No exceptions. No internal-only certificates.

RP-HPLC Analysis

Every lot measured by reverse-phase HPLC. FRAG 176-191 consistently achieves 99.2%+ purity across batches.

ESI Mass Spec

Electrospray ionization mass spectrometry confirms exact molecular weight and rules out structural isomers or impurities.

Lot-Specific CoA

Your Certificate of Analysis references your exact lot number with actual chromatogram data — not a generic template.

Research Context

Theoretical Research Analysis

All research information below reflects published preclinical literature only. This product is not for human use, consumption, or clinical application of any kind.

Selective lipolysis mechanism studies
Adipocyte fat metabolism research
GH fragment pharmacology
IGF-1-independent fat reduction models

FRAG 176-191 is routinely used as a tool to separate the fat-metabolizing effects of GH from its anabolic and growth-promoting actions. Multiple studies have confirmed adipocyte specificity in in vitro and in vivo lipolysis assays.
