I understand that you are supposed to run clen 2 weeks on then 2 weeks off for no longer than 12 weeks. Does that mean a total of 12 weeks, which would mean you only need a 6 week supply? Or does that mean that you are taking it for 12 weeks total, which would make the entire duration of the cycle 24 weeks? I want to know how much clen to buy and how much it will cost me.
