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.
- Half-Life
- 30-45 minutes injectable; longer with nasal spray formulation
- Minutes to hours depending on route; IV half-life approximately 10-30 minutes
- Admin Route
- SubQ, Intranasal, Oral
- Oral (liposomal preferred), Sublingual, Intravenous, Nebulized/inhaled, Topical

- Once or twice daily
- 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
