Glutathione
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.
Glutathione is the body's master endogenous antioxidant tripeptide, composed of glutamate, cysteine, and glycine. It neutralizes reactive oxygen species, supports detoxification in the liver, recycles other antioxidants (vitamins C and E), and plays a central role in immune function, DNA repair, and cellular redox balance.

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
  • Primary endogenous antioxidant and free radical scavenger
  • Supports hepatic detoxification of xenobiotics and heavy metals
  • Recycles vitamins C and E to maintain antioxidant network
  • Modulates immune function and T-cell activity
  • Skin brightening via inhibition of tyrosinase (IV/topical routes)
  • Neuroprotective in oxidative stress-related conditions
  • Mitochondrial protection and energy metabolism support
Side Effects
  • Localized injection site reactions
  • Headache (rare)
  • Hypoglycemia risk in combination with insulin (very rare)
  • Oral bioavailability is limited (largely hydrolyzed in gut); liposomal or sublingual forms preferred
  • IV administration: rare allergic reactions, vein irritation
  • High-dose supplementation may cause zinc depletion over time
  • Inhaled glutathione may trigger bronchoconstriction in asthmatics
