TB-500 by Zyvex Pharmaceuticals
What Is TB-500?
TB-500 refers to a synthetic fragment of thymosin beta-4, a protein involved in cell migration and tissue repair. It is one of the most referenced peptides in recovery research. Zyvex Pharmaceuticals supplies it as a 5 mg lyophilized vial for reconstitution.
Research interest in TB-500 centers on tendon, ligament and muscle recovery, with protocols dosing subcutaneously on a two to three times weekly schedule. It is studied for faster tissue healing and reduced recovery time between hard training sessions, which places it alongside BPC 157 in repair-focused stacks.
TB-500 Research Use
TB-500 is dosed in milligram steps, subcutaneously, after reconstitution with bacteriostatic water.
| Protocol | Dose | Schedule |
|---|---|---|
| General recovery | 2.5 mg | Twice weekly |
| Tissue focus | 2.5 mg | 3 times weekly Common |
| Short dense block | 5 mg | Loading, first 2 weeks |
Reconstitute the 5 mg vial with 1 ml of bacteriostatic water for a 5 mg/ml solution. A typical 4-6 week research window uses two to four vials.

What is TB-500?
TB-500 refers to a synthetic fragment of thymosin beta-4, a protein involved in cell migration and tissue repair. Zyvex Pharmaceuticals supplies it as a 5 mg lyophilized vial.
What is the right TB-500 dosage?
Research protocols use 2.5 mg two to three times per week. A 5 mg vial covers about two weeks at that schedule.
How often should you inject TB-500?
TB-500 is typically injected subcutaneously two to three times weekly, unlike daily peptides.
How long does TB-500 take to work?
Some users report reduced inflammation within 1-2 weeks; tissue-recovery effects build over a 4-6 week protocol.
How long does TB-500 stay in your system?
The thymosin beta-4 fragment has a relatively short half-life, which is why twice-weekly dosing is the research standard.
TB-500 vs BPC 157: which for recovery?
BPC 157 is dosed daily and acts locally; TB-500 works systemically with twice-weekly dosing. Many protocols run them together.
Can TB-500 and BPC 157 be stacked?
Yes - the combination is a common tissue-repair stack covering both local and systemic recovery.
What are the side effects of TB-500?
TB-500 is considered well tolerated; reports are minor and mostly injection-site related. Human safety data are limited.
How do you reconstitute TB-500?
Reconstitute the 5 mg vial with 1 ml of bacteriostatic water for a 5 mg/ml solution, then draw the research dose.
