Sore Joints on Winny tabs--help!!!!

I have begun an 8 week cycle of 50 mg of winstrol tabs per day the first two weeks, next 4 weeks 100 mgs ED, then back down to 50 mgs ED for the final two weeks. My problem is it is my fourth day on the winstrol and I am experiencing pain in my joints already. My knees hurt when I squatted two days ago and they never hurt otherwise and my shoulders were very painful today while benching. I know deca is used to combat this but i get tested by the NCAA so does anyone know of any over the counter supps I can take to lubricate my joints and get rid of the pain? I have heard dsmo is good for this, but I would like to hear some opinions. Any help would be appreciated. thanks
