Tax included where applicable. Shipping calculated at checkout.
TB-500 is a synthetic analogue of Thymosin Beta-4 (Tβ4), one of the most abundant intracellular peptides in mammalian tissues. It replicates the active actin-binding region responsible for cell migration and tissue repair. Published research in Nature demonstrated its role in cardiac cell survival and repair following ischaemic injury.

Research Overview
About this compound
What does the research say?
TB-500 replicates the active actin-binding region of Thymosin Beta-4 (Tβ4), a 43-amino acid peptide present in virtually all human and animal cells. Its primary biological function is regulating actin polymerisation, which directly influences cell motility, migration, and tissue repair.
In preclinical models, TB-500 promoted new blood vessel formation, accelerated wound healing, and reduced pro-inflammatory cytokines. A landmark study published in Nature showed that Thymosin Beta-4 activated integrin-linked kinase and promoted cardiac cell migration, survival, and cardiac repair following ischaemic injury.

Why does quality matter with TB-500?
TB-500 is a complex peptide that requires precise synthesis. Its biological activity depends on correct folding of the actin-binding domain. Impurities or degradation products can interfere with this critical structure.
At Camo Chem, every batch is tested by an independent 3rd party laboratory. We publish the full Certificate of Analysis for every batch, and you can verify the results directly with the lab. We do not self-certify. Ever.

definetely felt it helping me heal my injuries i had for months
★★★★★
Works well, speedy delivery
★★★★★
I wasn’t expecting to break through a plateau with this - my introduction to peptides was life changing. Safe, easy, fast delivery, very effective product. Will be ordering more and sticking with Chamo Chem from now on.
★★★★★
Good product, but expensive!
★★★★★
I like the product and the price is not great but ok especially for a tested quality. My only problem is that 2 vials had no vacuum in it and Im a bit worried that it was exposed or destroyed – maybe due to transport.
FAQ
Frequently asked questions
TB-500 is a synthetic analogue of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino acid peptide involved in actin regulation, cell migration, and tissue repair. Its CAS number is 77591-33-4. It is sold exclusively as a research compound.
Every batch meets a minimum of 98% purity as verified by HPLC. Testing is performed by an independent 3rd party laboratory. The CoA is available on this page.
