TB-500
Tax included where applicable. Shipping calculated at checkout.
TB-500 is a synthetic analogue of Thymosin Beta-4 (Tฮฒ4), 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.
Every batch is independently tested by a 3rd party laboratory. Certificate of Analysis available below.

Research Overview
About this compound
What does the research say?
TB-500 replicates the active actin-binding region of Thymosin Beta-4 (Tฮฒ4), 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.
These are not marketing claims. These are peer-reviewed, published results. You can verify every reference below.
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.

I wasnโt 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.

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 โ maybe due to transport.
