I think 600mg's is the minimum and quite possibly the maximum...a happy medium.
400 is for those low on cash, and 800 is probably the highest you would want to go..........
I'd take it for AT LEAST 10-16 weeks as it is VERY slow acting. It will make you look great, but don't expect a whole lot of muscle gain with it alone....of course, there are a few who respond very well with it and gain moderate amounts of muscle.
It can be stacked with any kind of cycle....I like it with the usual cutting drugs...Fina, winny, test, A-50, etc....
