How long does it take for oral winstrol to start working?

Depends on your dosage...(if you are a male, it should be 50mgs everyday), but normally between week 2 and 3 (should be running it minimum 6 weeks), but like everything else in life everyones different. Expect it about 2-3 wks. Make sure your diet and cardio and workouts are in check or you will waste your money and not see anything.
