crystal mdma dosing?

Hey drugit,

Rolled plenty in the past, but usually pills and not for a while (6 months?). Only time I've had crystal it was dosed out for me and I don't remember amounts..

Getting a cpl of grams; what's a good suggested dose and what's the max anyone would recommend staying below? (thinking serotonin syndrome, etc). My normal dose would be 3-4 decent strength pills over a night.
