You can buy TB-500 from HEEZ Research, which stocks it in a single 10 mg lyophilized vial and ships from the USA. Everything HEEZ supplies is for in vitro laboratory research — not for human or veterinary use.
TB-500 is a synthetic peptide corresponding to the characterized region of thymosin beta-4, a naturally occurring 43-amino-acid protein. The product name refers to the synthetic fragment rather than the full-length protein.
Thymosin beta-4 is the full 43-residue sequence; TB-500 is the shorter synthetic construct derived from it. They are related by sequence but are not the same molecular entity, which is why the listing names both.
TB-500 from HEEZ Research is independently tested by an accredited third-party laboratory using HPLC for purity and mass spectrometry for identity. Every peptide we supply is over 99% pure. Certificates of Analysis are published on the product page as testing is completed — review the report before you order. A certificate records the identity, purity and quantity measured for the material supplied, so you can confirm what you received matches what was ordered.
Sealed lyophilized TB-500 vials are stable at ambient temperature in transit and ship without cold packaging. On arrival, store the sealed vial per the storage conditions on its certificate of analysis.
Three: GLOW (70 mg, with GHK-Cu and BPC-157), KLOW (80 mg, adding KPV) and Wolverine (10 mg, 5 mg alongside 5 mg BPC-157).

About TB-500
What is TB-500 peptide?
TB-500 peptide is a synthetic 43-amino-acid research peptide corresponding to the full sequence of thymosin β4, an actin-sequestering protein, supplied by HEEZ Research as a lyophilized powder for in vitro laboratory use. HEEZ supplies the full-length N-acetylated sequence, the form referenced in most of the in vitro literature, rather than a short fragment.
How does TB-500 work?
In vitro, TB-500 is characterized by actin binding through its LKKTET motif (residues 17-23) — it sequesters G-actin monomers in solution — which is the assay readout most often cited for it. It is highly water-soluble in assay media and has no disulfide bonds.
How HEEZ tests TB-500
Solid-phase synthesis, reversed-phase purification, lyophilization.
