Marquis Reagent Sample Test

An excellent application of the Marquis reagent is in identifying the presence of NBOMe. LSD is often sold disguised as NBOMe and consuming NBOMe can lead to a bad/unpredictable experience or can be dangerous as well.
If the reagent reacts with a color change when used on a blotter, it means the blotter isn't safe to consume and contains NBOMe or another substance but not LSD/LSD analogues.
When buying the Ehrlich reagent, consider buying this reagent as well.
The 5ml bottle contains enough reagent for 75-100 tests.
