Some pre-workouts that I take (Jack3d & HemoRage) have compounds that are similar to amphetamines (DMAA & Schizandrol). They make your ****ing heart beat superfast, because they are Central nervous system stims. Can taking these amphetamine like supps hinder muscle gains? also I am about to be prescribed adderall, but refusing because I dont want to hinder muscle gains, can anyone let me know if they find out anymore information? Thanks
