BPC-157 / TB-500 is a research-grade blend of two synthetic peptides supplied strictly for laboratory research use. This page describes what the compounds are and how each lot is characterized. It makes no claim about any effect or application — it is reference information about identity, classification, and analytical testing.
Identity and classification
BPC-157 is a synthetic pentadecapeptide — a chain of 15 amino acids — whose sequence corresponds to a partial fragment of a protein identified in gastric juice (its name derives from “body protection compound”). TB-500 is a synthetic peptide corresponding to the active, actin-binding region of thymosin beta-4, a naturally occurring peptide. Both are studied in laboratory research as peptides of interest in cell-biology contexts such as angiogenesis and actin regulation.
How each lot is tested
Every batch is analyzed by an independent, ISO/IEC 17025-accredited U.S. laboratory. Identity is confirmed by mass spectrometry — the measured molecular weight is matched to the expected mass of each peptide — and purity is measured by HPLC-UV and reported as a percentage for that specific lot. The full method is described on our Lab Testing & Analytical Methodology page.
Format and handling
Supplied as a lyophilized (freeze-dried) powder in a sealed vial — the format peptides are held in for stability — and intended to be handled only by qualified professionals in an appropriate laboratory setting.
Documentation
Each lot ships with its own certificate of analysis. Review the certificates on our Lab Reports page, learn how to read a COA, and confirm a specific vial by its lot number on the Verify a Lot page. View this compound in the catalogue: BPC-157 / TB-500 20 mg.
