TB-500

TB-500 vials, kits and recovery blends

Thymosin Beta-4 is a naturally occurring protein involved in binding actin, the structural filament cells rely on to move and change shape. TB-500 is a synthetic peptide modelled on the active region of that protein, and it is studied in research on cell migration, blood-vessel formation and tissue repair. As with most peptides in this area, the evidence base is largely preclinical, and TB-500 is not an approved medicine. Listings on this page include standalone TB-500 vials and kits, plus combination products that pair it with BPC-157. Some brands also sell a shorter TB-500 fragment; its name and composition are stated on the listing so it is not mistaken for the standard peptide. For each product you can see the brand, strength per vial, number of vials and price per milligram, which makes it easier to spot genuine value among kits of different sizes. Independent purity reports are shown wherever a brand has provided one. Payment is handled through escrow, so the brand is paid only after your order has arrived. Problems found before release, including a failed independent test, can be raised as a claim.

Frequently asked questions

How does TB-500 relate to Thymosin Beta-4?

Thymosin Beta-4 is the full natural protein. TB-500 is a synthetic peptide based on its active region, the part associated with actin binding. Research uses the shorter synthetic version because it is simpler to produce. Some brands also offer a TB-500 fragment, which is named separately on its listing.

Are BPC-157 and TB-500 blends compared differently?

Yes. A blend splits its total milligrams between two peptides, so the listing gives the amount of each one alongside the kit size and price. Compare blends with other blends, and single-compound vials with single-compound vials, to keep the price-per-milligram figure meaningful.

When should I release payment for a TB-500 order?

Release it once the parcel has arrived and you are satisfied it matches the listing. If anything is wrong, open a claim first, because released orders cannot be refunded. If you take no action and no claim is open, payment releases automatically a set number of days after delivery.
