What to expect
A typical course of TB-500 in Wyoming.
The science
How TB-500 works, and what the research shows.
How it works
Thymosin Beta-4 (TB-500) is a 43-amino-acid peptide that promotes cell migration, differentiation, and tissue repair at a systemic level.
It works by binding to actin, supporting wound healing throughout the body — not just at one site.
Clinical evidence
Thymosin Beta-4's tissue-repair biology is well characterized: it promoted cardiac cell migration and survival after injury in influential animal work and supports corneal and dermal wound healing in preclinical models.
Bock-Marquette et al., Nature 2004Synthetic Tβ4 has reached human trials for wound healing and eye conditions with encouraging safety but limited efficacy data.
TB-500, the widely used fragment of Tβ4, has not itself been through human clinical trials.
