Yes, when you stop it'll go away fairly fast, but when you're on it can cause some serious problems; some will supplement with deca while on a winstrol cycle. I wouldn't recommend it. From years of usage, I have exprienced "dry" joints numerous times, it's not fun nor healthy.
Winny is a 5-alpha reduced substrate which blocks aromatase, the primary enzyme for the manufacture of estrogen in males; it also partially blocks the progesterone receptor. What this all means is less water retention and as fluid is drawn out from the bursae (little fluid-filled packets which cusion ligaments), we experience dry and painful joints. These can be bad, especially for BB'ers 40's +. A little Deca (100-200mg/wk) will counteract this effect. Glucosamine + chondroitin is good too.
