need info about mdma effects on water retention

[Easyrolling]

Hey peeps, Im new to this site which looks awsome, and need some helpful advice about a situation.I need to know wheter mdma can be taken whilst using a muscle building subtance such as creatine??I know creatine increases water retention in muscles and want to know if the effects of mdma inhibition of diuretic hormones can be dangerous whilst on creatine.

If anyone could help me I would be really appreciative, because I know a mate who is finishing his exams and really wants to get muddy when he's finished but is currently on creatine and so is apprehensive.

Peace n love
