Mechanism of Action
TB-500 upregulates actin expression, promoting cell migration, proliferation, and differentiation at injury sites. It also reduces inflammatory cytokines and promotes blood vessel formation, supporting tissue repair in preclinical models.
Storage & Handling
Store lyophilized at -20°C or 2-8°C. Reconstituted: 2-8°C, use within 30 days.

Frequently Asked Questions
What is the difference between TB-500 and BPC-157?
TB-500 is derived from thymosin beta-4 and primarily promotes cell migration via actin upregulation. BPC-157 is a gastric peptide that modulates nitric oxide and growth factors. They are often studied together for complementary mechanisms.
How should TB-500 be stored?
Lyophilized TB-500 should be stored at -20°C for long-term storage or 2-8°C for short-term. Reconstituted peptide should be refrigerated at 2-8°C and used within 30 days.
Is TB-500 the same as thymosin beta-4?
TB-500 is a synthetic fragment of the full thymosin beta-4 protein. It contains the active region responsible for the primary biological effects studied in research.
