Head-to-head comparison of Adipotide and HGH Fragment 176-191 — mechanism, side effects, legal status, and pricing.
Adipotide (FTPP) is a chimeric peptidomimetic developed in the Arap/Pasqualini lab (originally at MD Anderson) that couples a 9-residue homing motif (CKGGRAKDC) — isolated by in vivo phage display as a ligand for prohibitin on white-adipose-tissue vasculature — to the D-amino-acid pro-apoptotic domain D(KLAKLAK)2. It is an experimental research compound, NOT FDA-approved for any indication. A clinical-development program in prostate-cancer-associated obesity reached early-phase testing and was ultimately discontinued.
HGH Fragment 176-191 is a synthetic 16-residue disulfide-cyclized peptide corresponding to the C-terminal region (residues 176–191) of human growth hormone. It is classified as a lipolytic/GH-fragment peptide, not a full growth hormone. The compound is prohibited at all times under WADA Section S2 (Peptide Hormones, Growth Factors, Related Substances and Mimetics). Not FDA-approved for any indication; clinical development of the related analogue AOD9604 was discontinued in 2007 after a pivotal Phase IIb obesity trial failed its primary efficacy endpoint.

Foundational proof-of-concept in obese mice (Kolonin et al., Nat Med 2004, PMID 15133506). A 4-week dosing study in spontaneously obese rhesus macaques showed substantial body-weight and fat-mass loss and improved insulin sensitivity but produced dose-dependent renal proximal-tubule toxicity (Barnhart et al., Sci Transl Med 2011, PMID 22072637). A small Phase 1 trial in obese prostate-cancer patients was initiated and later terminated; the program was permanently discontinued. No published human efficacy data. Grey-market human use is unstudied and carries documented nephrotoxicity risk.
No human data were found for the native peptide (CAS 66004-57-7, Phe176) itself. All identified human clinical work was conducted on AOD9604, a distinct N-terminal Tyr-substituted analogue: six sponsor-run, randomized, double-blind, placebo-controlled trials (Phase I–IIb, 2001–2006, ~900 total subjects, including a ~502-subject 24-week Phase IIb obesity trial) assessed safety and later weight-loss efficacy. Reported: good tolerability, no serious adverse events, no IGF-1 elevation—but the pivotal Phase IIb trial did not meet its primary weight-loss endpoint versus placebo and Metabolic Pharmaceuticals discontinued development in 2007. In obese Zucker rats, oral AOD9604 (500 µg/kg/day × 19 days) reduced body-weight gain by >50% and increased adipose lipolytic activity without impairing insulin sensitivity. In obese and lean mice, both hGH and AOD9604 reduced weight gain and increased fat oxidation and plasma glycerol; unlike hGH, AOD9604 caused no hyperglycemia and did not compete for the hGH receptor. In β3-AR knockout mice, chronic lipolytic/weight effects were lost while acute energy-expenditure increases persisted. Intra-articular AOD9604 combined with hyaluronic acid outperformed either agent alone in a rabbit collagenase-induced knee osteoarthritis model.
Key references
Adipotide and HGH Fragment 176-191 are both in the Metabolic category and may have overlapping mechanisms. Researchers should review both profiles carefully, understand the mechanisms of action, and monitor the relevant biomarkers when combining compounds in the same class.
