Before you buy: the vendor check

One page. Print it, screenshot it, or keep it open in a tab. Every line is a lesson in this module, compressed.

1. The vendor publishes a lab report (COA) for the exact batch I am buying.
2. The report names a real, independent lab, and I can verify it with that lab.
3. The report shows purity (HPLC) with the graph, not just a number.
4. The report shows an identity test (mass spec) confirming what the powder is.
5. The report shows an endotoxin result, since this is for injection.
6. The report is dated within the last several months.
7. The lot number on the report will match the lot number on the vial.
8. Community test results for this vendor exist, and they are recent and clean.
9. The website makes no medical claims (no "heals," "treats," "cures").
10. The vendor has a history longer than this year.
11. I can pay in a way I can dispute. If not, I am only sending what I can afford to lose.
12. First order is small. One vial, checked, before anything bigger.
