the NRG3 of today is most unlikely to be anything than MPA (methiopropamine), Ethylphenidate, Nitracaine or a combination of those and some other powder. you can buy those things separately for far cheaper, and an electronic scales from many electronics shops (they don’t ask questions as there are many perfectly legitimate uses for one).
at least you then know how much is there, what chemicals could interact with one another and reduce your risk of overdose.
