KNOW THE COMPOUND

What is TB-500?

TB-500 should not be treated as interchangeable with full-length thymosin beta-4. Analytical research identified a marketed TB-500 preparation as the short acetylated fragment Ac-LKKTETQ. That distinction matters when comparing product specifications and publications.

A 2024 study examined that fragment and its metabolites in laboratory systems and rats. In a cell-based wound-healing experiment, a metabolite showed activity while the parent compound did not. A finding about the metabolite is not the same as a finding about TB-500 itself.

What comes with your selection?

One 10 mg vial per unit, its selected lot reference, and access to the matching demonstration certificate. Original supplier specifications, handling and storage instructions will be needed for a live listing.
