Does anyone have any experience with amphetamine sulphate? I am thinking of getting a gram the guy who is selling it charges $50/g is that good? I don't have much any experience with amphetamines but I have done coke a few times and liked it. I also rolled 2-3 times. What can I expect? The source is extremely reliable and had informed me that the product is at least 70% if not purer. NOTE: I am talking about straight AMPHETAMINE SULPHATE NOT Meth!
