I would strongly advise against redosing after one hour for a few reasons. First of all, if it's really MDMA (no way to tell without a test kit, no matter where you get it from) it won't start really kicking in for an hour. There will be no way to tell "how you are feeling" at that time, as you won't be peaking yet. Second of all, if it is something else like BZP, it takes much longer for it to kick in. Read the adulterated pill reports on pillreports.com and you will often see people who waited and since nothing happened or they thought it was a "low dose" they took another only to wish they hadn't, as large doses of some of these adulterants come with very nasty side effects.
