how george? lets see...i very well might be wrong though, im not a neurologist, but i still am not too opposed to the idea of double dropping, even if i were wrong.
MDMA is in all likelyhood, neurotoxic to begin with, you agree?
if you drop 2 at once, while yes, that is a higher dose, but..
A. no pills in america (other than apparently mints) have more than about 90mg of MDMA. Pokeballs, one of the first batches were DEA tested, 90mg each. So lets say you have pokeballs, acknowledged as MDMA High on PR. Thats 180mg of MDMA if you double drop, assuming that the pokeball stamp hasnt been faked or that the presser lowered the amount of MDMA per pill. Thats still not a fantastically high dose. Enough to floor most people, yes, enough to be "dangerous"? No.
Not moreso than a regular dose of MDMA, that is. And also, it sounds like the OP has some tolerance, which means that 180mg doesnt go as far as it would for an intolerant user.
B. If you take 1 pill, then another when you peak, you are extending the action of the droog. As in, MDMA is causing neurotransmitter release longer. I would think it would be more stressful on the brain to endure such conditions for longer periods than to just have one larger massive release (like wut would happen with 2 pill)
and, its a waste of MDMA anyway. IME redosing, until you get ridiculous with your booster doses, gets you maybe an hour more of actual effect, for enough MD to get a decent effect off of in the first place. I see no reason NOT to double drop if you are experienced enough and know what youre doing (along with good tested pills) because you're not going to OD on MDMA anyway. Could just be me, but the only times ive had good pills, no MDMA tolerance whatsoever, ive still wanted more from pills that were apparently MDxx high. OP if you think you are ready and can handle it, go for it, just be more careful than usual..you wont be getting ridiculously unheard of doses. It could just be me, but i do not understand how people roll "so hard" from individual pills. Could just be me knowing that really no pills have even .1 in them, but the 2 times i had good MDxx high pills i wasnt satisfied with the effects..with NO mdxx tolerance id start with at least 1.5 pills. But then again, i dont particularly like (or take) low doses of anything so..
