TB-500
Thymosin Beta-4 fragment
Synthetic fragment of the naturally occurring thymosin beta-4. Researched for cell migration and tissue repair.
§ 01
Research notes
Mechanism
TB-500 is a synthetic peptide based on a fragment of thymosin beta-4, a naturally occurring 43-amino-acid protein involved in actin regulation, cell migration, and tissue repair. Preclinical research focuses on its role in cell migration to injury sites and angiogenesis.
Research dosing
Twice-weekly injection at 2–5 mg per dose is the most commonly cited research protocol. Loading-phase variants front-load higher doses for the first 4–6 weeks.
Audit focus
For TB-500, the variance between vendors is mostly on identity confirmation rather than purity. We've seen multiple grey-market batches that were under-strength rather than off-spec; mass-spec identity tests catch these.
