Thymosin Beta-4 fragment promoting tissue repair, flexibility, and reduced inflammation.
TL;DR — TB-500 is a recovery & repair peptide with a typical starting dose of 2.5 mg. For a 5 mg vial, add 2 mL bacteriostatic water to yield 2.5 mg/mL.
Add 2 mL of bacteriostatic water to a 5 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 2.5 mg/mL.
What is the recommended dose of TB-500?
A typical research dose is 2.5 mg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a TB-500 vial?
A 5 mg vial reconstituted with 2 mL BAC water yields approximately 2 doses at 2.5 mg each.

What is the half-life of TB-500?
TB-500 has an estimated half-life of several days when administered subcutaneously, supporting less frequent dosing such as twice weekly during loading phases. Steady-state tissue levels persist longer than plasma levels.
What does TB-500 do at a molecular level?
TB-500 sequesters G-actin, preventing actin polymerization and promoting cell migration, angiogenesis, and tissue remodeling. It upregulates metalloproteinases and downregulates inflammatory cytokines, facilitating repair in connective tissue, muscle, and heart.
Is TB-500 typically used alone or stacked with BPC-157?
TB-500 is frequently stacked with BPC-157 in repair protocols. TB-500 primarily promotes systemic tissue remodeling and angiogenesis, while BPC-157 provides strong local healing and gut-protective effects. The combination is considered synergistic by many researchers.
