HGH Fragment 176-191 at a glance

HGH Fragment 176-191 is a short synthetic peptide matching the final stretch of human growth hormone, a segment that contains a disulfide-linked loop near the C-terminus. Researchers at Monash University in Australia investigated this region after finding that it appeared to carry some of growth hormone's effects on fat metabolism without its growth-promoting activity. A closely related analog, AOD-9604, came out of the same research program and was later taken into clinical testing.

What it is studied for

The fragment is proposed to act through a different route from intact growth hormone. In obese rodent studies, it was reported to increase lipolysis and reduce lipogenesis in fat tissue, apparently without activating growth hormone receptor signaling, raising IGF-1, or impairing insulin sensitivity. Some papers suggested involvement of beta-adrenergic pathways in fat cells, but the receptor responsible has not been identified with confidence. Much of the mechanistic understanding rests on a small number of studies, many of them using the AOD-9604 analog rather than the fragment itself.

Research and regulatory status

Evidence for the fragment itself is preclinical. The related AOD-9604 analog went into human trials for obesity, and its developer stopped that program after later-stage results did not show meaningful weight loss compared with placebo. Independent replication of the fat-metabolism findings in people is lacking. HGH Fragment 176-191 is not an approved medicine, and growth hormone fragments are prohibited under sports anti-doping rules.

Checking the lab data

A credible report should confirm identity by mass spectrometry against the mass calculated for the stated sequence, and the vendor should say exactly which sequence and modifications the product carries, since this fragment and AOD-9604 are often conflated. HPLC purity should come from a lot-specific chromatogram, ideally showing the intact disulfide rather than reduced or dimerized forms. The lyophilized cake should be white.

Compound: HGH Fragment 176-191
Vial strength: 5mg
Vials per kit: 10
Total content: 50 mg
Price per mg: $1.56
Sold by: BioPepta
Ships from: China
Lab report: Independent report attached

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Concentration arithmetic: one 5 mg vial dissolved in 2 mL gives 2.5 mg/mL, or 5 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

Is HGH Fragment 176-191 the same as AOD-9604?

They are very closely related. AOD-9604 is described as growth hormone residues 177 to 191 with a tyrosine added at the N-terminus, and because residue 176 of growth hormone is itself a tyrosine, the two can be identical or nearly so depending on how a vendor defines them. A lab report with sequence and mass resolves the question.

Does the fragment raise IGF-1 like growth hormone?

Rodent studies of the fragment and its analog reported no meaningful rise in IGF-1 and no growth-promoting effects, which is why the region attracted interest as a way to separate metabolic from growth activity. Those observations come from a limited set of studies and have not been confirmed by independent human research.

How much HGH Fragment 176-191 is in this listing?

10 vials of 5mg each — 50 mg in all. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.
