TB-500 fragment 17-23 (Ac-LKKTETQ) is the active sequence of thymosin beta-4 responsible for tissue repair and cell migration. Full research guide with mechanism, dosage context, and comparisons.
TB-500 is a synthetic peptide fragment of thymosin beta-4 (Tβ4), a naturally occurring 43-amino acid protein found in nearly all human and animal cells. It plays a key role in tissue repair, cell migration, and inflammation regulation. TB-500 specifically consists of the active region of Tβ4 (amino acids 17-23) responsible for actin binding and cell motility.
TB-500 works primarily by upregulating actin, a cell-building protein essential for tissue repair. It promotes angiogenesis (new blood vessel formation), reduces inflammation, and enhances cell migration to injury sites. Research suggests it activates satellite cells in muscle tissue and promotes keratinocyte migration for wound healing.
While both are healing peptides, they work through different mechanisms. TB-500 primarily promotes systemic healing through actin regulation and cell migration, while BPC-157 works locally through growth factor modulation and gut-healing properties. Many researchers study them in combination for synergistic effects.
TB-500 is legal to purchase as a research chemical in most countries. However, it is banned by WADA (World Anti-Doping Agency) and most sports organizations. It is not approved by the FDA for human use. Always check your local regulations before purchasing.
Published research in journals like the Annals of the New York Academy of Sciences and FASEB Journal has shown thymosin beta-4 promotes wound healing, reduces inflammation, and supports cardiac tissue repair in animal models. The peptide has demonstrated promise for tendon, ligament, muscle, and skin repair in preclinical studies.
