Analytical testing verifies that TB-500 research material is the intended peptide at a documented purity.
HPLC purity
HPLC resolves the target peptide from truncated or deletion sequences and quantifies purity as a percentage of total peak area.
Identity by mass spectrometry
Mass spectrometry checks the measured mass against the expected value for the TB-500 sequence — the pairing is explained in HPLC vs mass spectrometry.
Documentation
Every batch carries a certificate of analysis, ideally backed by independent third-party testing.
Available in the BPC-157 + TB-500 research stack.
