Intended Use and Limitations

This product is supplied for Research Use Only (RUO) and is not intended for human or animal consumption. It must not be used for diagnosis, treatment, cure, or prevention of any disease and must not be compounded, ingested, injected, or otherwise administered to humans or animals. Any scientific literature or background information associated with TB‑500 or Thymosin Beta‑4 is provided solely to describe their chemical and research characteristics and should not be interpreted as guidance for clinical use, wound or tissue healing, hair growth, cardiac repair, “regeneration,” performance enhancement, or other health‑related outcomes.​

Handling, Storage, and Quality

TB‑500 should be handled using standard laboratory practices appropriate for peptide reference materials, including suitable personal protective equipment and controlled laboratory conditions. Lyophilized vials should be stored according to internal laboratory protocols for peptides, typically in a cool, dry environment protected from light and moisture to help preserve material integrity prior to use.​

Each lot is accompanied by a Certificate of Analysis (COA) providing identity, purity, and analytical data (e.g., HPLC, mass spectrometry), allowing researchers to document material quality and suitability for their specific experimental applications. Users are responsible for ensuring that all work with this compound complies with applicable regulations, institutional policies, and ethical standards.​
