About HGH Fragment 176-191
HGH Fragment 176-191 corresponds to the last 16 amino acids of the 191-residue human growth hormone. The region contains the two cysteines, at positions 182 and 189, that form one of the hormone's disulfide bonds, so whether a synthetic lot is supplied with that bond formed should be stated on its documents.
Work on the C-terminal region of growth hormone, beginning in the 1990s, investigated whether it carries lipid-metabolism activity separately from the growth-promoting activity of the full hormone. The closely related AOD9604 spans residues 177–191 with an added N-terminal tyrosine.
Research context
The fragment is studied in adipose tissue models of lipolysis and lipogenesis, and in comparisons with full-length growth hormone and AOD9604 that aim to separate metabolic effects from IGF-1-mediated growth effects.
What to confirm for HGH Fragment 176-191
Check these points with our team before you order:
- Whether the lot is the linear peptide or the disulfide-bonded (cyclized) form.
- The exact sequence, since HGH Fragment 176-191 and AOD9604 are often confused.
- The number of boxes you need and the US delivery destination.
- Which lot documents you require before ordering, such as an identity or purity report.
HGH Fragment 176-191: frequently asked questions
How does HGH Fragment 176-191 differ from AOD9604?
Both come from the C-terminal region of growth hormone. HGH Fragment 176-191 covers residues 176–191; AOD9604 covers residues 177–191 with an extra tyrosine at the N-terminus.
Why do the product codes read FR10/Frag10?
The supplier lists each strength under two equivalent codes, such as FR10 and Frag10 for the 10 mg vial. Either code identifies the same presentation.
Which HGH Fragment 176-191 presentations are listed?
5 presentations are listed: 2 mg (FR2/Frag2), 5 mg (FR5/Frag5), 10 mg (FR10/Frag10), 12 mg (FR12/Frag12), 15 mg (FR15/Frag15). Each is packed 10 vials per box, and every presentation has its own specification page and product code.
How do I request a quote for HGH Fragment 176-191?
Open the presentation you need and use Ask price to message PureForm Biosciences on WhatsApp, or add several materials to the inquiry cart and send them together. Pricing, current availability and lot documents are confirmed in that conversation.
