TB-500
A powerhouse recovery peptide loved for repair, flexibility and mobility.
What is it?
TB-500 is a synthetic version of thymosin beta-4, a protein the body already produces to help tissue repair. It is one of the best-known recovery peptides and a natural partner to BPC-157 — together they form the classic recovery stack that so many people ask for.
Why people choose it
- A recovery favourite alongside BPC-157
- Popular for whole-body repair, not just one area

What is it used for?
- Recovery and tissue repair
- Flexibility and mobility

- General physical resilience
How it works
TB-500 relates to a natural protein involved in how cells move and organise themselves while tissue repairs. This 'whole-body' style of action is why people reach for it when they want more than spot-treatment recovery.
