Rppeptides's 'COA' is the raw-material factory's own QC sheet, the giveaway is the line 'complies with the manufacturer's standard' and a factory lot code. The seller has slapped its logo on the maker's self-assessment. That's the supplier grading itself, twice removed from anything independent, and presented to you as third-party proof. Aggravating: pushes GLP-1 'pens'/weight-loss framing.
