Don't do this research chemical unless you want to feel like a living God blissed out on MDMA and cocaine simultaneously.It is highly addictive and I suggest you google a research chemical site and order some immediately.It's like hanging out with Krsna.Avoid.I'd suggest about 5 grams to start with.It's heavenly,blissful and totally joyous.Avoid.Much less of a headfuck than ephylphenidate.
