Doing this to try to get the dxm metabolites, benzedrex, benzos and muscle relaxers out too and try to have an intense meditative experience after a few days. The stackers are ephedra free, just caffine 200mg, yerba mate leaves, camella sinensis (green tea) polyphenols, guggulsterone (natural steroid) cassia mimosoids (?), white willow bark (aspirin pretty much).
