>>I would love to see new stimulant come out that relases serotonin and dopamine like the way meth does
in Depot form tablets that start from 100% relase decreasing each day in 7 days and you'd get no come down at all.

I don't think that the time-release would defeat the crash entirely. You'd still be in want of sleep, food, dopamine, have too much nor-epi, etc. As an additional piece of evidence, long-acting stimulants, like meth-amp, can still have nasty crashes.
>>Wouldnt hurt if it relased all serotonin the way mdma does, but kept the high going on for as long as you wanted..>>
This isn't physiologically possible. The endogenous synth for 5ht is rather slow, so 5ht releasers can deplete (but not entirely) your brain of 5ht within a matter of hours. This is why meth users can do multi-day binges but ecstacy-users can't really (or when they try, it turns into an expensive stimulant).
