About TB-500 (Thymosin Beta-4)
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring protein involved in cellular migration and tissue repair. Preclinical research suggests TB-500 supports recovery from soft-tissue injury via systemic mechanisms rather than localized action. Often paired with BPC-157.
// How it works
How it works
TB-500 is a synthetic version of Thymosin Beta-4, a protein your body produces in response to injury. It promotes cell migration, blood vessel formation, and reduces inflammation. Often stacked with BPC-157 for compound effect.
// Who it's for
Who it's for
Athletes with recurring soft-tissue strain. Post-injury recovery, particularly muscle tears. Patients also using BPC-157 — the two are commonly combined.
// What to expect
Your timeline
Loading phase: 2 mg twice weekly for 4 weeks. Maintenance: 2 mg weekly. Most patients notice meaningful change in 4–6 weeks.
