Well the only test I know that can test Potency (not only presence), is the EZ-White which test for cocaine only.
My question is:
When, using the common Marquis and other DanceSafe kit (Mandelin etc..), to determine purity, Is it possible to test for potency, regarding to the color given ?
I.E Suppose we got a pill that contain 5mg Meth and another one which contain 80mg. Will the color has, at least, some different Tint/Hue from each other or NADA! ?
