a couple of people have said, and i agree, that gold cks and pink hearts mix really well and they provide one hell of a fucking long lasting and really full on night. is it because one contains mdma and the other mda or vice versa? since i noticed earlier that the two are supposed to mix really well. also another person had said that the gold cks have 2cb in them and thats why there is no comedown - i have asked everyone i know about the lack of comedown and have had them all agree.
