If I stack 15mg of Ephedrine with 15mg of Adderall 100mg of Phenylpiracetam together with Modafinil 100mg into a capsule for working out Etc. Would that change the duration of the effects? As Ephedrine/Adderall/Phenylpiracetam lasts roughly the same time 3/5 hours but if I?ve added Modafinil which can last 15 hours. All mixed together would that change the time? Or would the drugs that last 3/5 still last three-five just working out redose times so that it?s even throughout the day and so I can sleep at night.
