@sam.ha241: This is why I exist. My job isn't just placing orders. It's being the person who says "show me the raw data" — in person, in Mandarin, standing in the lab. 3 things I check on every factory audit that a PDF can't show you: 1. Is the HPLC instrument the same model listed in their capability statement? 2. Does the lyophilizer capacity match what they claim they can produce? 3. Are the retained samples actually retained — or just relabeled leftovers? A COA tells you what they want you to know. An audit tells you what they don't. What's the one thing you wish you could verify about your China peptide supply? #peptide #ghkcu
