Depends on the dosing of each tab. If they are 10mg then 6 per day is a good dose. Usually the minimum run for winny is 50mg daily and the max is 100mg daily. 100 is a little high imo, so i'd stick with 50mg espeically if its your first time.
cycle up do 50mg for a week then 60 and on I have never heard of anyone going over 80mg.Im 185lbs and for me I was happy with 40mg saw real good gains with 400 EQ each week and 40mg a day of winny.But now I use the shot so.
