Thymosin Beta-4- 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.
- Thymosin Beta-4 is an endogenous 43-amino acid peptide that is the primary intracellular actin sequestering peptide. It promotes tissue repair, reduces inflammation, regenerates hair follicles, and protects cardiac tissue. Closely related to TB-500 (the active fragment), it is used for systemic tissue recovery and anti-aging.
- Half-Life
- Minutes to hours depending on route; IV half-life approximately 10-30 minutes
- Not well characterized; likely similar to TB-500 (~1–2 hours)
- Admin Route
- Oral (liposomal preferred), Sublingual, Intravenous, Nebulized/inhaled, Topical
- SubQ, IM

- 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
- Systemic tissue repair and regeneration
- Promotes cardiac recovery after myocardial infarction
- Hair follicle regeneration and anti-hair-loss
- Anti-inflammatory (systemic)
- Wound healing acceleration
- Neuroprotection after brain injury

- Anti-aging at cellular level
- Synergizes powerfully with BPC-157
- 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
- Generally very well tolerated
- Injection site reactions
- Mild fatigue at initiation (repair signaling)
- Rare: mild inflammatory response
