Read any COA in 12 checks.

A Certificate of Analysis is supposed to prove what's in the vial. Most people can't tell a real one from a convincing fake — and the gray market knows it. This free field card gives you the engineer's 12-point read, on a single page you can print and keep.

The 12-Point COA Quick-Check

  • The only two numbers on a COA that actually matter — and why 99% purity can still mean you got shorted
  • The recycled-HPLC-graph tell that catches lazy forgeries instantly
  • The one verification step that beats any Photoshop job
  • The "old certificate" date scam, in plain sight
  • A print-and-tick layout, built to sit next to you

It teaches you to evaluate a source. It does not name a vendor or a dose — on purpose.
