About this test

BPC-157/Thymosin Beta-4 5mg blend from Simple Peptide was independently analyzed on February 25, 2026, confirming 99.945% purity by HPLC with LC-MS detection. The blend composition includes BPC-157 at 6.04mg and Thymosin Beta-4 at 5.48mg. The sample appears as white lyophilized powder and passed endotoxin threshold testing across both replicates, indicating low endotoxin levels suitable for research applications.

BPC-157 is a pentadecapeptide researched for neuroprotective and tissue-repair properties, while Thymosin Beta-4 is a 43 amino acid polypeptide studied for immune modulation and cellular regeneration. A purity level of 99.945% indicates minimal contamination and high-grade synthesis quality. Mass spectrometry identifies both peptides with BPC-157 [M+2H]2+ at m/z 710.15 and TB4 [M+6H]6+ at m/z 826.00.

The full certificate of analysis (COA #2602240179) is available through Freedom Diagnostics Testing.
