I started a sus and tren hex cycle a couple months back 4 th week in I caught a bad cold and I came off. Its been a while,cold is gone .But the problem is, now what ever I do( like pick something up or after a set) I am short of breath. If I try to run or just move something I cant breath.I had an ekg, a stress test and a chest x ray and everything comes up negative .I try to get on the treadmill but can only last 2 minutes.Any suggestions or help plase send.
