About Thymosin Beta-4
- What it is
- Thymosin beta-4 is a naturally occurring 43 amino acid protein that binds and sequesters actin, influencing cell migration, tissue repair, blood vessel formation, and inflammation. Laboratory and animal studies describe roles in wound healing and tissue regeneration, and a synthetic ophthalmic formulation has been evaluated for dry eye and neurotrophic keratopathy. It is the full-length protein, distinct from the TB-500 fragment, and it is not approved.
- How it works
- It binds and sequesters actin to regulate the cytoskeleton, supporting cell migration, tissue repair, and blood vessel growth.

Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
