It is advised to check the references for photos of reaction results. Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive.Home pill testing doesn't show up PMA in a pill in YouTube. For this reason it is essential to use multiple different tests to show all adulterants.
