A small piece of a natural repair protein. Popular for recovery, but barely tested in people.
Not approved, and banned in sport by WADA. In 2026 the FDA took it off its “do not compound” list, but that is not an approval.

TB-500 is a short, lab-made piece of thymosin beta-4, a protein found in almost every cell. Thymosin beta-4 helps cells move and build their inner “scaffolding”.
In lab and animal studies, thymosin beta-4 helps cells travel to wounds and supports new blood-vessel growth. Whether the small TB-500 fragment does the same in people hasn’t been shown.

Follow the storage conditions supplied on the batch label and certificate.
Keep the material in its original, sealed packaging. Follow your laboratory’s handling procedures and the supplied product documentation.
Refer to the lot-specific expiry date and stability documentation. Shelf life should not be inferred from the product name alone.
For solvent compatibility or preparation specifications, request the manufacturer’s batch documentation. Research protocols should be established by qualified laboratory personnel.
Every product comes three ways. It's the same peptide and the same amounts; what changes is the packaging, what's included and the price. Start with the pen kit box, which has the reusable pen, then refill it with dual-chamber vials.

The freeze-dried peptide and the bacteriostatic (BAC) water sit in separate chambers, divided by a rubber stopper. They stay apart until the cartridge is used.
The pen kit box has the reusable pen body with a dual-chamber vial, 12 disposable needles and a booklet. The drive, dial and indicator window stay with the pen: when a cartridge is empty, fit a new dual-chamber vial.
Choose the vial if you already have bacteriostatic water and your own lab supplies. It's the lowest price for the same amount.
