Also known as: TB-4, Thymosin Beta-4, Tβ4
TB-500 is the full-chain version of Thymosin Beta-4, a 43 amino acid peptide, and vendors also list it as TB500, TB-4, or Thymosin Beta-4. Worth knowing: that label is sold as the complete 43-residue chain, not the shorter LKKTETQ fragment, so the vial holds the full molecule. Listings are research-use-only, usually lyophilized powder in sealed vials, and it is stocked widely enough that prices spread far apart.
TB-500 vials commonly run 5 mg or 10 mg, and some vendors ship multi-vial kits, so a sticker price says little. The grid above reduces each listing to landed cost per mg, list price plus a shipping estimate over total milligrams, the only fair way to rank a 5 mg vial against a 10 mg one.
TB-500 is usually bought beside BPC-157, and the pair anchors the Wolverine stack and Tri-Blend stack. Price a blend against separate vials on the stack planner.
