2mg vial
TB-500 is a synthetic analogue representing the active region of Thymosin Beta-4 (Tβ4) - a 43-amino-acid regulatory protein expressed in virtually all human and animal cells. It has been studied for cell migration, angiogenesis, stem cell recruitment and the repair of muscle, tendon, ligament, cardiac and neural tissue.

Sequesters G-actin monomers to regulate actin polymerisation dynamics, driving cell migration, angiogenesis and tissue remodelling. Upregulates MMP-2 and promotes progenitor cell recruitment at injury sites.
Common research protocols use a 2–2.5mg loading dose twice weekly for 4–6 weeks, followed by 1.5–2mg once weekly for maintenance. Cycles typically run 6–8 weeks with 4-week breaks. Route: subcutaneous or intramuscular.
Plasma half-life approx. 30–80 minutes for free Tβ4, but SC/IM depot effects extend functional activity over several days per injection.
Reconstitute a 5mg vial with 1–2mL bacteriostatic water for a 2.5–5mg/mL working concentration. Gently swirl; do not vortex.
Lyophilised: 2–8°C for routine storage, or -20°C for long-term (stable 18–24 months). Reconstituted: 2–8°C, use within 30 days.
