TB-500 is A synthetic fragment of the naturally-occurring thymosin beta-4 protein. All ThePeptideCode products are laboratory research use only.

Mechanism & background

TB-500 corresponds to the active region of thymosin beta-4 — a peptide involved in actin sequestration and cell migration. In research models it has been associated with vascular formation, cell-migration responses, and tissue repair endpoints.

Common research applications

Tissue-repair research, comparative healing studies with BPC-157, hair-follicle research, vascular-formation work.

Reconstitution and storage

TB-500 ships as a lyophilised powder in a sealed glass vial. Reconstitute with bacteriostatic water following the step-by-step reconstitution guide. Once reconstituted, store at 2–8 °C for short-term use, or aliquot and freeze at −20 °C for longer storage. See the full dosage and storage guide.

Purity and batch verification

Every TB-500 batch shipped by ThePeptideCode is verified by an ISO 17025-accredited independent laboratory using HPLC (purity) and mass spectrometry (identity). Typical purity is ≥99%. Look up your batch ID on the verification page.
