so i always buy from the same guy, but usually he has a little bit of a different batch everytime.. the caps i bought from him this time has about 4x the amount of powder than the caps he sold me last time, its a bit more powdery/crushed up and lighter colored, compared to the little bit more crystalized brown stuff i got from him last time.. both times me told me there was .1g in each cap.. can the weight of mdma vary? because i seriously put both caps right next to each other, and this new stuff has so much more (to the eye atleast) he also told me its about 2-3x stronger...
