mechanism
How it works.
TB-500 is a synthetic fragment of thymosin β4, a naturally occurring 43-amino-acid protein found throughout human tissue. The fragment retains the biologically active region associated with actin regulation* and cell migration.
- ↳G-actin sequestration, n-term
Preclinical studies have explored TB-500 for systemic recovery* — meaning that unlike locally acting compounds, it is typically investigated for its ability to circulate and support repair across multiple tissue types simultaneously.
- ↳long t½, broad distribution
Researchers have paired TB-500 with BPC-157 in preclinical models on the rationale that the two peptides address distinct but complementary* repair mechanisms: one local, one systemic.

“Ordered Friday, arrived Tuesday. Lot code on the vial matched the COA they emailed. Cold-chain packaging held up well — vials were still cool when they arrived.”
Devon K · Winnipeg✓ verified
“Bought TB-500 after running BPC-157 from vitalitiRX for a couple cycles. Same packaging quality, same COA process, same lot-level traceability. Consistency is the thing I appreciate most.”
Meera S · Mississauga✓ verified
“Quality is what I'd expect at this price tier. The COA workflow is the standout — I've ordered the same compound from two other suppliers and neither would even tell me the lot number.”
