Common questions about TB-500
- What is TB-500?
- TB-500 is a synthetic fragment of the naturally-occurring thymosin beta-4 (Tβ4) peptide. It is studied in animal models for soft-tissue repair, actin sequestration, and inflammation modulation.
- Is TB-500 FDA-approved?
- No. TB-500 is not approved by the FDA or any major regulator for human use. It is sold by research-peptide vendors strictly for laboratory research.
- What is the half-life of TB-500?
- Rodent plasma studies report a half-life of roughly 1.5–3 hours, but tissue accumulation appears to prolong the functional effects beyond what circulating concentrations would predict.
- What dose of TB-500 is used in research?
- Published preclinical doses vary substantially by species, route, and endpoint. Pepticker does not publish a research dosing protocol — consult the original literature for the model you are reproducing.
- Is TB-500 the same as Thymosin Beta-4?
- No. TB-500 is a synthetic fragment of the full-length thymosin beta-4 molecule. Vendors selling 'TB-500' typically list this fragment; the parent compound is sold separately as Thymosin Beta-4 (TB-4).
- What is TB-500 commonly stacked with?
- Researchers most commonly pair TB-500 with BPC-157 in connective-tissue protocols and with GHK-Cu in skin and dermal-repair work, based on vendor and forum protocols.
