50mg of washed meth is plenty for me.I don't know if it works the same way with say amphetamine sulfate. I'm sure it is connected to the properties of meth that make a person extremely horny. Some people get this effect with meth but not at all with amphetamine sulfate (me for example). I have never got anything novel and special out of taking LSD on top of my regular 30 mg prescribed dexamfetamine for example - except maybe needing a higher LSD dose to disconnect my DNM and tamp down my ego-control to let the wonder begin.
