TB-500 Frag Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research
TB-500 Frag is a synthetic peptide fragment derived from Thymosin Beta-4 (Tbeta4), a naturally occurring 43-amino acid protein that regulates actin dynamics and cell behavior throughout the body. Rather than using the full Thymosin Beta-4 sequence, TB-500 Frag isolates the compound's most bioactive subsequences, particularly the Ac-SDKP tetrapeptide and the LKKTET actin-binding motif, targeting cell migration, angiogenesis, and anti-fibrotic activity. This guide covers what TB-500 Frag is, how it works, what the preclinical research shows, how it is used in community protocols, its dosing context, safety profile, and its regulatory and sports status.
