Why this research peptide
Thymosin Beta-4 fragment
Synthetic version of a peptide present in all human cells, studied in tissue-repair research.
Actin regulation
Main mechanism studied in vitro: binding to G-actin, involved in cell structure and migration.
Studied systemic profile
Unlike locally-acting peptides, TB-500 is studied for its body-wide distribution in research models.
Verified purity
HPLC + mass spectrometry analysis by an independent laboratory, certificate included with every batch.
Long-term storage
Lyophilised form stable for up to 24 months at -20°C for extended storage in the laboratory.
Discreet logistics
Plain parcel, France delivery 3-5 days, tracking included and neutral packaging.
What is TB-500?
TB-500 is a synthetic fragment of Thymosin Beta-4 (Tβ4), a peptide naturally present in all human cells, at particularly high concentration in platelets and wound fluid. It is studied in the research literature for its role in cell migration, angiogenesis and the inflammatory response. Used as a research reagent in the laboratory, frequently paired with BPC-157 in in vitro protocols. Lyophilised product supplied with an independent certificate of analysis — not for human consumption.
Mechanisms studied in research
The literature describes several mechanisms of action studied in vitro and in preclinical models. The items below summarise these mechanisms for informational purposes only, with no intent of human use.
Actin regulation
Binding to G-actin, a key cell-structure protein — TB-500's main studied mechanism of action.
Angiogenesis
Studied for its role in the formation of new blood vessels in laboratory models.
Progenitor cells
Subject of in vitro studies on progenitor-cell activation and tissue regeneration.
Laboratory reconstitution
Usual reconstitution concentrations for laboratory handling (bacteriostatic water, 0.9% benzyl alcohol). As TB-500 is a sensitive peptide, slow reconstitution along the vial wall is recommended. These values relate solely to the preparation of the research solution — they constitute neither a dosage nor a protocol for human use.
| Vial | Solvent volume | Resulting concentration |
|---|---|---|
| 10 mg | 2 mL | 5 mg/mL |
| 20 mg | 2 mL | 10 mg/mL |
| 30 mg | 3 mL | 10 mg/mL |
