We don't allow "what should I take" threads I am afraid - check the guidelines in my sig. You've been given a few suggestions here but as atm said your best bet is to do a bit of research yourself on bluelight (Ecstasy Discussion, Trip Reports, Psychedelic Drugs) and on other sites such as Erowid. If you have specific questions about a particular substance feel free to come back and ask, although remember that MDx drugs are discussed in Ecstasy Discussion and psychedelics such as the 2c-x and NBOMe series in Psychedelic Drugs rather than here.
Closed, pm me with any queries.
