TB-500 is a synthetic research peptide derived from thymosin beta-4, a protein found in nearly every cell in the body. In research it is best known around recovery: tissue regeneration, cell migration and the formation of new blood vessels. It is often mentioned alongside BPC-157, with which it forms the well-known "Wolverine" combination studied in recovery research. At GradePurity you buy TB-500 as a research-grade peptide: ≥99% HPLC purity and same-day shipping from the Netherlands.
What does TB-500 do?
TB-500 is best known in research circles around recovery. It is thought to play a role in the repair of muscle, tendon, ligament and skin tissue and in the formation of new blood vessels. That makes it a natural counterpart, and frequent companion, to BPC-157 in the recovery field.
How does TB-500 work?
TB-500 is derived from thymosin beta-4, a protein found naturally in nearly every cell. Its action centres on actin, one of the building blocks cells use to move and to build tissue. It is thought that TB-500 supports cell migration and so helps set repair processes and the formation of new blood vessels in motion. Most of the research comes from animal models.
TB-500 vs BPC-157, difference and combining
TB-500 and BPC-157 are often mentioned together, but they approach recovery by different routes. BPC-157 is derived from a stomach-protective protein and is mainly linked in research to the healing environment: blood flow, inflammation and signalling pathways. TB-500 works through actin and cell migration, more the cellular side of tissue repair. Because the routes complement each other, they are often studied as a combination in research, the well-known "Wolverine" stack. If you want to study both together, you build them yourself in the stack builder; individually you buy TB-500 or BPC-157 on its own page.
TB-500 dosage and reconstitution
TB-500 ships as a lyophilised vial that you mix yourself with bacteriostatic water. In the literature it is usually studied in weekly protocols, often with a slightly higher loading phase followed by a lower maintenance phase; the exact protocols vary by study. GradePurity gives no dosing or administration advice itself: we supply TB-500 as a research peptide only, and the details on this page (purity, vial size) are intended for your research documentation. After mixing, store the vial in the fridge (2–8 °C).
Side effects of TB-500
In research, TB-500 is known for a mild profile. The effects sometimes reported are light: tiredness shortly after administration, headache or a local reaction at the injection site. Because TB-500 stimulates cell division, the literature does mention caution with existing tumours or cell overgrowth. Hard data for long-term use outside of studies is still missing.
Is TB-500 legal? Do you need a prescription?
TB-500 is not approved as a medicine in the Netherlands. As a research-grade peptide, however, it may simply be bought and held for laboratory research; a prescription is not relevant here, nor is consumption. Important for athletes: TB-500 is on the World Anti-Doping Agency (WADA) prohibited list, both in and out of competition. GradePurity supplies it for research only, not for human use.
Purity and lab testing
Every batch of TB-500 is checked in the lab for purity (≥99%) and identity. So you know exactly what you are holding, that is the main difference from anonymous suppliers. The exact specifications are in the table at the bottom of this page.
