the first time i had meph, i had 2 grams of meph and one gram methylone. this lasted me for 5 or 6 nice, fun sessions, where i had invited 2 of my friend to. that means, on one of this evening everyone of us would do 200mgs of meph & 100mgs of m1, spaced out over a few hours, mostly taken as little lines, a bit bombed/dissolved in drinks. and that was enough for all of us, every time. were all very experienced with stimulants, e, blablabla....and have all had a tolerance to amphetamines at the time.
i think the problem is that meph&m1 are mostly advertised as e-alternatives; but imo they only start to feel like e when you`ve already overdosed.
they`re unknown substances and their effects differ from person a to person b, and they should be treated as such: carefully.
oh, and on my first evening with meph i drank a few beers, on the next day my stomach&chest felt pretty "funny"; a bit like they do when i get an anxiety attack, but still very different.
oh, yes, the source was reliable. more so than many others, i think....
be careful!
@solipsys: the first time it was really thrown on to the market was 2007 with all the neo-doves and so on, as far as i know. but im not sure, im not really into the rc-"scene"
