YES U CAN....I'm doin winny only right now (Zambons)...im trying to cut, im dieting and doing cardio, and i still put on about 6 pounds in 3 weeks, so if you were eating goood, im sure you could do 15 in 6 weeks. But lemme tell you ...winstrol is not that mild of a drug, i have done sust before and the only side effect i had was water retention. WIth this winny, i have some hairloss, increased acne and slight joint pain. So considering the sides and the injection frequency of winny i would agree with everyone else and do the Sust or another form of Test .
