- What's the HGH Fragment 176-191 price?
- £28.99 for one 5mg vial. Two vials are £52.18, three are £69.58 and five are £101.47, which is 10%, 20% and 30% off.
- Is HGH Fragment 176-191 the same as AOD-9604?
- Close, but not identical. This fragment is PubChem CID 16131230, 1,799.1 Da, starting Phe-Leu-Arg. AOD-9604 (CID 71300630, 1,815.1 Da) swaps that first phenylalanine for tyrosine. Both keep the Cys182-Cys189 disulfide bridge; neither is growth hormone itself.
- How fast is delivery?
- Same day, from Manchester, whenever you order. Royal Mail Tracked 24 aims for next working day delivery. Free over £40, otherwise £3.99.
- What else do I need with HGH Fragment 176-191?
- Bacteriostatic water, to dissolve the freeze-dried powder. We stock it, and you can add it from the Storage section above.
- How should I store HGH Fragment 176-191?
- Sealed vial: -20°C, away from light. Once reconstituted: 2-8°C, use within 28 days, and don't refreeze.
- Can I buy HGH Fragment 176-191 in the UK?
- Yes, for laboratory research. HGH Fragment 176-191 isn't a controlled drug in the UK (Class C covers whole somatropin, not this fragment) and has no UK licence as a medicine, so it's research use only, not for human use. You must be 18 or over.
About the HGH Fragment 176-191 peptide
HGH Fragment 176-191 is a synthetic 16-residue peptide copying the C-terminal tail of human growth hormone, residues 176 to 191, Phe-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe, with the native Cys182-Cys189 disulfide bridge. Frank Ng's group at Monash University studied this region of the hormone from the 1970s, and Metabolic Pharmaceuticals later developed the Tyr-substituted analogue AOD-9604. It is studied in lipid metabolism models. We sell it as freeze-dried powder in a 5mg vial, for laboratory research only.

HGH Fragment 176-191 in the research literature
Most of the Monash papers on the C-terminal region of growth hormone use fragments that start at residue 177, not 176, which matters when reading them against this vial. Wijaya and colleagues, 1993, studied glucose transport in rat adipocytes with an antilipogenic fragment; Natera and colleagues, 1994, ran a chronic study of synthetic hGH 177-191 in mice; Ng and colleagues, 2000, worked with a coded domain, AOD9401, in a rat model. The Tyr-substituted AOD-9604 then took over. Heffernan and colleagues, 2001, compared it with full-length GH in mouse models, including beta-3 adrenoceptor knock-out mice, and Metabolic Pharmaceuticals ran its clinical programme on that molecule, not on the native 176-191 sequence. Literature specific to the Phe-176 fragment sold here is therefore thin; its identity rests on the parent hormone's sequence and PubChem CID 16131230. Vanhee and colleagues, 2014, characterised AOD9604 in preparations seized in Belgium, and Dominikowski and colleagues, 2026, review GH fragments alongside the other GH-IGF1 axis peptides.
HGH Fragment 176-191 vs AOD-9604: which to order
The two vials differ by one oxygen atom. The native fragment starts Phe-Leu-Arg, 1,799.1 Da, C78H123N23O22S2. AOD-9604 starts Tyr-Leu-Arg, 1,815.1 Da, C78H123N23O23S2; the hydroxyl on the first residue is the whole change, and residues 177 to 191 and the disulfide bridge are identical. A 16 Da shift is easy to see on LC-MS, so the lab report, once published on this page, will settle which peptide is in the vial. AOD-9604 has the clinical history; the native fragment is the one WADA names as hGH 176-191 beside it. A sequence beginning YLRIV under the 176-191 name is AOD-9604. Both are 5mg vials. For HGH Fragment 176-191 UK orders, one vial first; two, three or five save 10%, 20% or 30%, same-day dispatch from Manchester, free UK delivery over £40.
