What the hell is going on, I am taking 200mcg of clen and 50mg of proviron , I wanted to start my cutting today and after I walked for 5 minutes max I could barely stand the pain in my calves and they are pumped as hell. I wanted to walk for 1 hour, what shall I do, is this gonna be like this I can't cut that fat without walking? It's mostly the front calves, and they get a burning sensation.
