Description
Synthetic fragment of Thymosin Beta-4 protein (specifically the actin-binding domain: Ac-LKKTETQ). TB-500 promotes cellular migration, proliferation, and survival. Thymosin Beta-4 is a 43-amino acid protein that regulates actin polymerization. TB-500 is the key bioactive fragment for healing applications. Also used in veterinary (equine) medicine.
Benefits:
Accelerated healing of muscle tears, tendon injuries, and ligament damage; reduced inflammation; enhanced joint flexibility and range of motion; cardiac protection (myocardial repair); hair growth stimulation; angiogenesis promotion; systemic distribution (benefits injuries throughout body regardless of injection site)
Side Effects:
Head rush or brief lightheadedness post-injection; nausea; fatigue / lethargy; injection site reactions; potential pro-angiogenic concern (theoretical tumor promotion risk in active cancer); temporary flu-like symptoms
For laboratory research only — not for human consumption.
