Gonadorelin
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.
Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.
Half-Life

~2–4 minutes (extremely short); pulsatile dosing required to avoid desensitization
Admin Route
Oral (liposomal preferred), Sublingual, Intravenous, Nebulized/inhaled, Topical
SubQ, Intranasal
Research
Typical Dose
250-1000 mg per day
100 mcg
Frequency
Once or twice daily
Twice daily (every 12 hours)
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
  • Maintains testicular size during TRT
  • Preserves fertility and sperm production during testosterone use
  • Stimulates endogenous LH/FSH production
  • Maintains HPG axis function during exogenous hormone use
  • Used for HCG-free TRT protocols
  • Helps restart natural testosterone production (PCT)
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
  • Injection site reactions
  • Headache
  • Nausea at initiation
  • Tachycardia (rare)
