Somatropin (HGH)- Summary
- 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.
- Somatropin is recombinant human growth hormone (rhGH), identical in structure to the 191-amino acid pituitary-derived growth hormone. It is FDA-approved for growth hormone deficiency, short stature, and wasting conditions. Off-label, it is widely explored for body composition, anti-aging, and performance enhancement, though significant risks accompany unsupervised use.
- Half-Life
- Minutes to hours depending on route; IV half-life approximately 10-30 minutes
- 2-3 hours (subcutaneous); 20-30 minutes (intravenous)
- Admin Route
- Oral (liposomal preferred), Sublingual, Intravenous, Nebulized/inhaled, Topical
- Subcutaneous, Intramuscular (less common)

- 0.15-0.3 mg/day (adults); titrated to IGF-1 levels
- Frequency
- Once or twice daily
- Once daily
- Key Benefits
- 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
- Increases lean muscle mass and reduces body fat (particularly visceral)
- Restores growth hormone deficiency (FDA-approved)
- Improves bone mineral density
- Enhances exercise capacity and recovery
- Supports skin thickness and collagen synthesis
- Improves lipid profile in GHD patients
- Explored for anti-aging and cellular regeneration
- Side Effects
- 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
- Fluid retention and edema (common, dose-dependent)
- Carpal tunnel syndrome
- Joint and muscle pain
- Insulin resistance and elevated blood glucose
