Short, printable, and built around a method you can actually run. No vendor names, no doses, no “trust me”. Start with the free one.

One page. Twelve checks, in the order I’d run them. Print it, keep it next to you, and work down it whenever a lab report lands. A blank or a fail on any line means stop.

16 pages, 12 parts. The reasoning behind every check on the card — an annotated report, a genuine one next to a forged one, what the tested data found, and the audit checklist at the back.
Short version: the card is the checklist, the Blueprint is the manual that teaches you to read one. Long version below.
| The COA Quick-Check Free · 1 page | The Sourcing Safety Blueprint $12 · 16 pages | |
|---|---|---|
| What it is | A checklist you tick. | The manual that teaches you to read one. |
| The 12 checks | All twelve, in order. | All twelve, plus why each one works and what it misses. |
| Reading an actual COA | — | A full report pulled apart section by section, annotated. |
| Spotting a forgery | Names the tells. | A genuine and a faked report side by side, every tell marked. |
| Verifying a document | Says to verify it. | The 3-step drill for checking a report at the lab, not the seller. |
| What testing found | — | What 6,441 tested samples actually showed, with citations. |
| Contamination | Flags it. | The tests a real release runs that gray-market skips, and why purity is blind to them. |
| Storage & degradation | — | Why a genuine COA still has a hidden expiry date. |
| Vendor red flags | Two lines. | A full section — the scams that end an audit before you open a PDF. |
| Best for | Keeping next to you when a COA lands. | Actually understanding what you're looking at. |
