Verification
Every batch is identified by a lot number, and its third-party certificate is listed here by lot. Measured values are shown only when they are real and independently verifiable.
Third-party testing in progress
We are currently having this product independently tested by a third-party laboratory. Its certificate of analysis will be published here as soon as the results are available — please check back soon. For laboratory research use only.
TB-500 is catalogued here as a short peptide of seven amino acids, corresponding to a fragment of the protein thymosin β4. It belongs in the tissue-repair research collection.
Vestrand supplies it as one production lot at a time, prepared for independent purity testing, with each lot's certificate on its verification page.
The detail that matters here is a name clash. “TB-500” is used for two genuinely different molecules — this short seven-amino-acid fragment, and the full-length thymosin β4 protein, which is many times larger. Everything on this page describes the short fragment, and the two should never be crossed.

TB-500 is a synthetic peptide corresponding to the actin-binding fragment of thymosin β4. It is catalogued in tissue-repair research as a reference for the short fragment, distinct from the full-length thymosin β4 protein.

Peptide
A short synthetic peptide corresponding to a tail-end fragment of human growth hormone, with one extra building block added at the front.
Peptide
A synthetic peptide of fifteen building blocks (a pentadecapeptide), based on a partial sequence of a protein first identified in gastric juice.
Peptide blend
A blend of two peptides — BPC-157 and TB-500 — supplied together. A mixture, not a single substance, with no identity of its own.
Peptide
A growth-hormone-releasing factor analogue of twenty-nine building blocks, also known as Modified GRF (1-29). Easily confused with the closely related sermorelin.
