Question about kits...

[sandman564]

So if a pill contain an MDxx and another substance how can you tell that their are two substances in the pill?

Different reagents test for different substances, and mixed results often show up as "swirls" in the reagent. (Orange swirls in purple/black Marquis results indicates MDxx + Amp.)

 

[sisterRay]

are there any kits that can test purity of dope?
