Shit i know people who take max 7 in one night and have been doing xtc for 4 years constantly and that is almost to much for them...Ive done xtc 4 times and pop 1-2 every roll and its bomb...My freind who was doing xtc for like 2 months straight every day almost was snorting 2-3 and taking 2-3 a day..He has sense gave up on xtc.
