BPC-157 Arginate vs TB-500

BPC-157 Arginate vs TB-500 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

BPC-157 Arginate
Healing & Recovery

BPC-157 Arginate is the arginine salt form of BPC-157, identical in the GEPPPGKPADDAGLV peptide sequence but with improved water solubility, aqueous stability, and oral bioavailability. The arginate counterion buffers GI microenvironmental pH, reducing acid-catalyzed peptide degr...

TB-500
Healing & Recovery

TB-500 is a synthetic fragment of Thymosin Beta-4, concentrated naturally in platelets and wound fluid. It promotes cell migration, angiogenesis, and systemic tissue repair via actin polymerization. Half-life of approximately 5 days enables twice-weekly dosing. WADA prohibited un...
