First time Moxy (5-MeO-MiPT). Need Advice.

Got some moxy, planning on volumetric dosing, and doing about 4mgs? Previous experiences with LSD, 1PLSD, MDMA, and bunch of other stuff. Really need advice on if 4mg is a good starting dosage. I am planning on doing with my GF, and we are really just looking for something on the 'lighter' side of things. Something like 'MDMA', but more sexual :D

I understand that this is a psychedelic, but I would really like to avoid a full on 'trip' as we want to do it in a more party environment. Last LSD trip was not too pleasant, and would really like to avoid that.
