AOD-9604 is a synthetic 16-amino acid peptide fragment corresponding to the C-terminal region (amino acids 176-191) of human growth hormone, with a tyrosine substitution at the N-terminus. It was developed by Metabolic Pharmaceuticals in Australia in the 1990s.

Research Dosage Notes

Not FDA-approved. Research dosages typically range from 250-500 mcg/day via subcutaneous injection, with 300-500 mcg/day being the most commonly cited. Phase II trials used up to 1 mg/day. Cycles often run 4-12 weeks. Over 900 participants across six controlled trials established tolerability.

Mechanisms of Action

4

Beta-3 adrenergic receptor activation

Moderate

Activates beta-3 adrenergic receptors in adipose tissue, triggering the release of stored fatty acids for energy use and enhancing fat oxidation.

Beta-3 adrenergic / lipolysis pathway

Lipogenesis inhibition

Moderate

Reduces accumulation of new fat in adipocytes by inhibiting de novo lipogenesis, working to prevent new fat storage while mobilizing existing fat stores.

Adipocyte lipid synthesis

GH-receptor-independent fat metabolism

Strong

Mimics the lipolytic fragment of growth hormone without activating the GH receptor, meaning no IGF-1 elevation, no blood sugar disruption, no water retention, and no cell proliferation effects.

HGH C-terminal fragment signaling (GH-receptor independent)

Anti-inflammatory modulation in joints

Emerging

Modulates pro-inflammatory cytokines including TNF-alpha, IL-6, and matrix metalloproteinases (MMPs), which play central roles in cartilage degradation.

Fat loss and lipolysis

Body Composition

Preferentially mobilizes stored lipids from obese fat cells, stimulating fat oxidation. Phase II clinical trials in humans showed dose-dependent fat reduction.

Moderate

Cartilage and joint repair

Recovery

Preclinical studies in rabbit osteoarthritis models showed enhanced cartilage regeneration with intra-articular injections, particularly when combined with hyaluronic acid.

No impact on blood glucose or IGF-1

Metabolic

Confirmed across six human trials: AOD-9604 does not elevate IGF-1, disrupt blood sugar, cause water retention, or promote cell proliferation, offering a favorable safety profile.
