OK, first time user. Bought 2 grams from *snip - no vendor discussion* of the big crystal stuff. Did 30mg, felt a lil buzz that lasted say about 2-3mins. It could of been a placebo? Then I did another 30mg line half a hour later. Nothing. Then did a 60mg line 45 mins later, still nothing. Now I've kinda gave up. Been a good 2 hours since last line and feel on a come down. feel to take more just to try kill of the come down. What did I do wrong? I am 13 stone. Use stims a awlful lot and high tolerence to amphetemine mdma, cocaine ect. So I'm guessing I must have high tolerence to this? But its brand new to my system so is that possible? What doseages should I be taking? Or worst of all was I sold fake stuff?
