The minimum standards for research-grade BPC-157 are: Purity 98% as verified by HPLC not just mass spectrometry, which cannot detect closely related impurities Mass confirmation by LC-MS or MALDI-TOF confirming the correct molecular weight (1,419.53 Da for BPC-157 acetate) Batch-specific Certificate of Analysis (COA) a generic COA not linked to the specific production batch is insufficient Endotoxin testing for in-vivo applications (LAL or equivalent) Why UK-Dispatched Supply Matters Peptides are temperature-sensitive
