Over TB-500
TB-500 is a synthetic peptide representing the active region of thymosin beta-4, the most abundant actin-sequestering protein in mammalian cells. It is widely studied for its role in cell migration, angiogenesis, and tissue repair processes. TB-500's mechanism — regulating actin polymerization to enable cell movement — makes it fundamentally different from other repair peptides and a mainstay of regenerative research.
TB-500 is a synthetic peptide representing the active region of thymosin beta-4, the most abundant actin-sequestering protein in mammalian cells. It is widely studied for its role in cell migration, angiogenesis, and tissue repair processes. TB-500's mechanism — regulating actin polymerization to enable cell movement — makes it fundamentally different from other repair peptides and a mainstay of regenerative research.
TB-500 is a synthetic fragment corresponding to the active region of Thymosin Beta-4 (Tβ4), a 43-amino acid naturally occurring peptide. Its primary mechanism involves binding to and sequestering G-actin, modulating actin polymerization which is critical for cell migration, wound healing, and tissue repair. TB-500 promotes: upregulation of cell-building proteins (actin), cell migration to injury sites, blood vessel formation (angiogenesis), downregulation of inflammatory cytokines, and extracellular matrix remodeling with collagen fiber organization. Unlike BPC-157 (which acts locally), TB-500 has systemic reach due to its molecular structure.

Bewijsniveau: Emerging
Experimental — Strong preclinical data for wound healing and tissue repair. Thymosin Beta-4 itself has been in clinical trials (cardiac, corneal), but TB-500 specifically has no completed human RCTs. Banned by WADA in equine and human sport.

Na reconstitutie: Refrigerate at 2-8°C, use within 30 days
Reconstitutiestappen uit de dataset
- Clean. Remove flip-top cap and swab rubber stopper with alcohol.
- Draw water. Draw 2mL of bacteriostatic water into syringe.
- Inject water. Insert needle through stopper and slowly inject water down the side of the vial.
- Dissolve. Gently swirl until fully dissolved. Solution should be clear.
- Label. Label vial with date and concentration (5mg/mL). Refrigerate immediately.
- Dose. Loading: 2.5mg (0.5mL / 50 units) 2x/week. Maintenance: 2mg (0.4mL / 40 units) 1x/week.
Veiligheid en beperkingen
Onderzocht voor: Wound healing, Cardiac tissue repair, Corneal healing, Muscle recovery, Flexibility improvement
Gemelde aanvang: 1-2 weeks; loading phase effect often noticed by week 2
Gemelde duur: 6-8 week cycles (3 weeks loading + 5 weeks maintenance)
Meldingen uit de community: Consistently positive when stacked with BPC-157. Users report improved flexibility, faster healing from muscle tears, and reduced chronic inflammation. Some report temporary head rush immediately post-injection and mild lethargy. Loading phase uses significant product (20-30mg per cycle).
