you have to understand that the theory behind the 2 on 4 off cycle is that the body doesn't start having bad sides until you are on for 3 weeks. so you are only supposed to have active drugs in your system for 21 days, max. since you are using tren (2? day half life), anavar (8 hour half life) & winstrol (8 hours) the drugs should be deactivated by day 17 or so.
300 mg clomid on day 1, 50 mg clomid a day days 2-21 is what i heard bill roberts advise on a 14 day cycle.
also, you have to take into account that even if you only gain 5 lbs. in 2 weeks you will still end up the same in the end. lets say you do an 8 week on, 8 week off cycle. you may gain 20 lbs of muscle in the 8 weeks on, then you need to take 8 weeks off before you can go on again. with the 2 weeks on, 4 weeks off you can do 3 'on' cycles in 16 weeks. so even if you only gain 5 or 6 lbs per 2 week cycle in the end you will gain just as fast as if you did 8 week cycles.
