In that case, some of that stuff MIGHT help, like the Catuaba or Ashwaghanda....I would forget the Red Ginseng.
I would try an extract of Avene Sativa, or "Wild Oats", and also use the recommended dosage of a zinc supplement. Maybe combine it with Guarana, which has a combo of xanthines including caffeine.
Wild oats, for me anyway, significantly enhance sensuality and sensation.....it would be a great filler for MDMA. And extract should be a white powder.
