MDA : The rush makes you feel stoned, cliff-stlye comedown
MDMA : Great buzz, amazing comedown, does not energize nearly as much as the other two.
MEMA : Speedier than MDMA, a little sketchier the next day
C2-B : Hallucinate
CT-7 : Hallucinate
PCP : Trust me you'll know
Crystal : partially denatured by your stomach, you'll get the jitters but not nearly as intense. it'll make you a bitch still.
Speed : If taken as part of a pill, you'll have difficult time discerning between the meta-ampethamine and the standard one.
Most pills have some combo of MDA, MDMA and MEMA..
well. most good pills.
Also, I have found pillreports to be dead on most of the time. Ever sinec I started using it, Havent had anything close to a bad roll.
