A peptide COA may show purity—but leave major safety questions unanswered. What was actually tested? Does the report match your batch? Are sterility, endotoxin, and heavy-metal results available? Missing information doesn’t prove contamination, but a purity percentage alone doesn’t establish safety. That’s why I created DirtyPeptides.com—to independently review what a COA does and does not show.
