Winny is killing my joints at 50mg EOD. I did a deca/d-bol cycle, and have been using winny to help keep gains, harden up, and get rid of the gyno I always get from deca. Well, its worked great for all that, but my knees are utterly fucked right now. I couldn't do one rep at 135 if I had to right now. Two weeks ago I was squatting 405 for 3 sets of 5 reps too! My shoulders are a bit stiff too. I'm going to finish the rest of my winny just to make sure all the gyno is out of my system, but I won't be training heavy thats for sure. For me at least, I'll never do winny alone. With deca its okay because deca helps lube your joints, but without deca, winny has been murder on my joints. What a shame too, because the shit actually makes me stronger than either deca or d-bol, and also gives me better pumps too!
