Frequently Asked Questions

What is H-Fragment 176-191?
H-Fragment 176-191 is a synthetic peptide fragment corresponding to the C-terminal region (residues 176-191) of the growth hormone molecule, with the sequence H-Phe-Leu-Arg-Ile-Val-Gln-Cys(1)-Arg-Ser-Val-Glu-Gly-Ser-Cys(1)-Gly-Phe-OH. It has molecular formula C78H123N23O22S2 and a molecular weight of 1799.1 g/mol. Pure Health Peptides supplies it as a lyophilized powder strictly for in vitro laboratory research.
What is H-Fragment 176-191 studied for in research?
In controlled laboratory settings, H-Fragment 176-191 is studied as the C-terminal fragment of the growth hormone molecule. Research literature reports that this region has been examined in lipid-metabolism study models and that the fragment does not reproduce the full growth-promoting activity of the intact hormone. These are research findings; all applications are non-clinical.
How does H-Fragment 176-191 differ from AOD9604?
H-Fragment 176-191 is the unmodified C-terminal fragment of the growth hormone molecule, whereas AOD9604 is a modified analog of that same region carrying a structural modification intended to improve stability of the molecule. The two are studied as distinct, individually characterized research compounds; refer to each lot-specific Certificate of Analysis for exact identity.
What are H-Fragment 176-191's chemical specifications, and what size does it come in?
H-Fragment 176-191 has the molecular formula C78H123N23O22S2 and a molecular weight of 1799.1 g/mol (refer to the lot-specific Certificate of Analysis for the exact value). It is supplied as a lyophilized white powder in a 5 mg vial at greater than or equal to 99% purity (HPLC). Store in a cool, dry place away from light and moisture.
Where can I buy H-Fragment 176-191, and is it third-party tested?
H-Fragment 176-191 is available from Pure Health Peptides as research-grade material in a 5 mg vial at greater than or equal to 99% HPLC-verified purity. Every production lot is third-party tested in the US, with a lot-specific Certificate of Analysis available for verification.
Is H-Fragment 176-191 intended for human or clinical use?
No. H-Fragment 176-191 is for research use only and is not intended for human or veterinary use. It has not been evaluated by the FDA and is not a drug, food, cosmetic, or dietary supplement. It is supplied only to qualified research professionals for in vitro laboratory research, and KYC verification is required prior to fulfillment. Any use outside of controlled in vitro research is strictly prohibited.
