Additionally, most studies are open-label and unblinded, raising concerns about bias and limited generalizability
A research-grade BPC-157 COA should show an HPLC chromatogram with a purity percentage of 99% or higher, mass spectrometry confirming identity matching the GEPPPGKPADDAGLV sequence (molecular weight 1419 Da), a batch or lot number, testing date, and analytical laboratory name
These signs may indicate degradation or contamination
