I'm about to do a clen cycle and you start off with 1 pill the first day 2 on the next day and so on until you start to really feel it.(5-7 pills a day is normal). BUT everyone is different try that out first. you do clen on 2 weeks on and then for 2 weeks of eca's. So 2 weeks on 2 weeks off. If you have any other questions do a search i found out alot of things on the board with that and i'm still learning!!!!!
P.s. If his diet and cardio isn't in check it should be.
