TB-500

TB-500 is a lab-made peptide of 43 amino acids that mimics a natural protein called Thymosin β-4. Researchers use it to study how cells build and rearrange their internal “scaffold” (actin) and how they transport materials around inside themselves.

Note: TB-500 is intended for research purposes only and is not approved for human consumption or use. All products are shipped in lyophilized form and must be reconstituted to a liquid for research and testing.  We are unable to provide any dosing instructions. All products should be considered pharmaceutical grade.
