this stack is almost a pre-contest stack... there are many reprocussions from using nolvadex, proviron and T3
Nolv and T3 can have a severe rebound effect
proviron is great precontest because it makes you super hard but it also drys out your hair and skin... 4 weeks if sufficient for a contest...
Clen is great to burn fat and preserve muscle when doing increased cardio and dieting...
Winny can have sides but at 10mg it should not be too bad.. common sides are acne, swollen and sensitive clit, mood swings but you will get vascular and strong with better endurance...
Hope that helps break it down a bit... More information is necessary to better access your particular situation...
