I am finishing up a very successful cutting cycle. I have been running 280mg of test e for the last 4 months. I got down from 207 to 190 and did not lose an ounce of muscle. I completely achieved my goals, I am very hard, very lean and increased my strength dramatically. For the last 2 months of my 6 month cycle I have recently added winstrol. Before I added the winstrol I was running like a champ. I would run 4-5 miles every few days, no problem. However, now that I have added the winstrol I can only run for about 10 minutes before I have to stop. Its not because I am getting winded, but because my entire legs below the knees feels like they are on fire. My calves get tight, my shins burn, my ankles hurts. The pain is unbearable. It is a burning type of pain everywhere. It feels like a gigantic build up of lactic acid all thorughout my lower legs. I have actually had winstrol do this to me before, but I don't know why. I am thinking about stopping the winstrol because it is negatively affecting my running and instead of helping me get even leaner my weight is actually going up, because I can not effectively do my cardio any more. Does anyone know why winstrol does this?
