Hi I am looking for some advise, I have been training for 22 years and I am a fitness instructor for the 18. I always wanted to take steroids to increase my size but the only thing is I had Open Heart Surgery when I was "18 Months old". I have synthetic valves where my aorta & pulmonary valves are and I have NEVER had any trouble with my heart and I stick to a good training regime and diet. Can I try using steroids will it affect my heart? What should I try first?
