THE way he reccomends running the clen, is start at 1 pill perday, and then increase it by 1 pill every 2 weeks until u reach 6 pills, and dont go over that, so that would make it what 12 weeks straight on clen? and then in the march 2003 MD he says that he uses t3 for the entire 12 weeks leading up to a show starting at 12.5 mcgs per day and increasing by half a tab every 2 weeks.
