How to test LSD: if you intend to check is LSD blotter evenly dosed, first you need LSD test kit to check it for adulterants. Pure LSD can be laid on any kind of blotter paper (or other surface) and can’t be identified by appearence. To test LSD use reagent tests Ehrlich, Hofmann, Marquis and Mecke in single-use or multiple-use test kits. Using a set with different reagents helps detect adulterants – 90% will react with 1 out of 3 reagents, and 95% with 1 out of 5.

Reagents presumptively indicate PRESENCE, but not PURITY or QUANTITY. A positive or negative test result does not mean that the substance is safe. No substance is 100% safe.
