AOD-9604
AOD-9604 corresponds to the C-terminal fragment 176-191 of human growth hormone with an additional N-terminal tyrosine. In animal models, lipolytic effects without GH-typical adverse events (insulin resistance, IGF-1 rise) were reported. In humans, these preclinical findings did not translate into clinically relevant weight reduction in the four phase-2 obesity trials. The exact human mechanism of action is unclear; the GH receptor is not classically activated by the fragment.
GHRP-2
GHRP-2 binds with high affinity to the GH secretagogue receptor (GHSR-1a) in the pituitary and hypothalamus. Activation leads to rapid release of pulsatile growth hormone. Unlike GHRH, GHRP-2 acts via a separate pathway and can be combined synergistically with GHRH to elicit maximal GH responses in provocation tests.

Frequently asked questions
- What is the difference between AOD-9604 and GHRP-2?
- AOD-9604 is classified as "Crescita", while GHRP-2 is classified as "Crescita". AOD-9604: Synthetic 16-amino-acid peptide corresponding to the C-terminal fragment of human growth hormone (hGH 176-191). Originally developed by Metabolic Pharmaceuticals as an oral obesity therapy; all phase-2 trials missed the primary endpoint. No marketing approval. The Australian TGA Schedule 4 classification is often misunderstood. GHRP-2: Synthetic hexapeptide of the GH secretagogue family. Approved in Japan as GHRP Kaken as a diagnostic test for GH deficiency. Not available as a medicine outside Japan. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, AOD-9604 or GHRP-2?
- The highest available evidence level is "RCT sull'uomo" for AOD-9604 and "Studio sull'uomo" for GHRP-2. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of AOD-9604 and GHRP-2 in Germany and the United States?
- Germania: AOD-9604 — Non approvato, GHRP-2 — Non approvato. Stati Uniti: AOD-9604 — Non approvato, GHRP-2 — Non approvato. These are factual summaries with source and review date on the individual pages.
