By providing antioxidant effects, copper peptides help prevent the breakdown of existing collagen and elastin while protecting newly formed proteins from oxidative damage

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

Research peptides are commonly stored in cool, dry laboratory conditions away from excessive heat and moisture
