Does EZ test go bad?

[torontojew]

Forst question is does an EZ test go bad if left at room temptures? What is proper storage?


Second does and MDMA (purple/black) VERY slowly indicate low levels of MDMA? Thanks

Marquis reagent should be kept at around 4-5 deg C. Yes it does age, but if stored properly it should last at least 18 months from date of manufacture.

To your last question; it can be other factors, such as interference from binders, whether the tablet contents are homogenous etc. It's therefore generally not recommended that strength be decided on by the speed of reaction.
