TB-500 vs Glutathione

Side-by-side comparison of key properties, dosing, and research.

Recovery & Repair
TB-500
Anti-Aging & LongevityImmune Support
Glutathione
Summary
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring peptide found in nearly all human and animal cells. It promotes cell migration to injury sites, accelerates tissue regeneration, and reduces chronic inflammation.
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
  • Enhances muscle tissue regeneration
  • Accelerates healing of wounds and injuries
  • Reduces inflammation and pain
  • Improves flexibility and mobility
  • Promotes new blood vessel formation
  • Supports hair growth and skin health
  • May improve cardiac function after injury
  • Systemic healing effect — works at distance from injection site
  • 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
  • Injection site discomfort
  • Fatigue (rare)
  • Headache (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
