Recently i have been getting great results from masteron although i noticed it does make you lose your hair a little bit, but i doesnt hurt your joings like Winny does. I noticed both are good cutters but with masteron you need to be pretty lean for it to work. but it def will help you get vascular and hard. I like both but i find winny to be good at getting to 10 percent then jump on mast to get down to 6 or 7
