you also need to post up what your goals are, are you looking to cut up? or put on weight. Most guys that say if you want to take off the body fat you only need 3-4 IU/day max with winstrol and t3/clen would be a good stack. If your looking to put on weight you probably want to still use the t3, add in some good test, and use insulin (need to know what your doing b4 you mess around with this stuff) and a lot of guys say 4-6 IU/day.
You best bet is to wait until some of the vets are online and they can give you all the info you need, but you can't just take what everyone says on here as fact, do a bunch of research yourself b4 you get into it.
A minimum of 3 months or your just going to be wasting your time and money.
