Question Different precursors

[kokkewiet]

I bought BMK from the same supplier on two different occasions.
First batch had a tripping affect, a definite high, but you slept like a baby, second one no tripping but keeps you awake, no sleep.
Any idea of what the different precursors could have been?
Both where made the same way, with dicloromethane.

This is just how variable amphetamines are from batch to batch until time will make you approach the preparation in an ever perfecting similarity of timings and execution of steps. You forgot to mention the product or the relevant reactant formamide or N-methylformamide, methylamine or ammonia, DCM is the solvent and all I can guess is that temperature couldn't have risen much as DCM boils at 39,5*C. In principle no amphetamine woud put you to sleep too soon.
