TB-500 (Thymosin Beta-4) – 10mg

The cytoskeletal heavyweight of the tissue repair category. TB-500 is a synthetic version of Thymosin Beta-4 — a naturally occurring peptide found in nearly every human and animal cell — and it’s been a research compound of intense interest for its roles in cell migration, wound healing, and tissue regeneration across cardiac, dermal, and musculoskeletal models.

Thymosin Beta-4 binds G-actin and acts as a major intracellular regulator of actin polymerisation — the cellular process behind migration, proliferation, and morphological change. Through this and related pathways, TB4 influences angiogenesis, modulates inflammation, and recruits progenitor cells to sites of injury. TB-500 is widely used as a functional research analogue, though the precise relationship between the synthetic peptide and full-length TB4 in vivo remains an active area of investigation.

TB-500 and TB4 have been the subject of small early-phase human trials, primarily in dermal and ophthalmic wound healing contexts. Most data remains preclinical, with no broad regulatory approval to date.
