Summary
AOD-9604 is a modified fragment of human growth hormone (residues 177-191) with an additional tyrosine residue that significantly enhances bioavailability. Originally developed as an anti-obesity drug by Metabolic Pharmaceuticals, it stimulates lipolysis and inhibits lipogenesis without the diabetogenic effects of full GH.
Collagen peptides are short-chain amino acid sequences produced by enzymatic hydrolysis of whole collagen (typically bovine or marine). They serve as bioactive signals that stimulate fibroblasts and chondrocytes to produce new collagen, elastin, and cartilage matrix, supporting skin, joint, bone, and gut health.

Key Benefits
  • Selective fat loss without anabolic side effects
  • No effect on blood glucose or insulin resistance
  • Improved bioavailability over Fragment 176-191
  • GRAS (Generally Recognized As Safe) status in Australia
  • Potential cartilage repair and anti-inflammatory properties
  • Does not suppress natural GH production
  • Stimulates skin collagen and elastin production
  • Reduces wrinkle depth and improves skin hydration
  • Supports joint cartilage regeneration
  • Reduces joint pain in osteoarthritis
  • Promotes bone density (stimulates osteoblasts)
  • Improves gut barrier integrity (leaky gut)
  • Supports hair and nail growth
  • Excellent amino acid profile for muscle recovery
Side Effects
  • Localized injection site reactions
  • Headache (rare)
  • Hypoglycemia risk in combination with insulin (very rare)
  • Excellent safety profile as food-derived protein
  • Rare: bloating or GI discomfort at high doses
  • Rare: allergic reaction (bovine or fish allergy)
