I do between 200 and 250 mg, for me, it will develop rapidly and you will feel the effects a longer time... that is if you me. I don't like boosters, they make you have a shitty comedown. I am very used to mdma also so I do larger amounts in the rare instance I decide to use this great substance. I am not the safest cat out there, but hell these substances all involve some risk no matter how miniscule they may be or appear to be.... ROLL ON!
