Beginners dose with oral Winny?

Like Stonecold said 50mg ed is a standard dose. The minimum dose I think you could get away with is 50mg eod for a beginner but I would only do that if you are stacking it with something.
People get good good results with around 35mg a day. Especially if you are a beginner with gear.
My first time using Winstrol (winny), I used 50mg of zambons eod. I got pretty good results. It depends on the quality of your gear, but I would opt for 50mg ed.
