As we all know if we put something foreign in our body it can have positive and negative affects. Recently a friend of mine was working in a stress lab doing a stress test on a early 30 year old guy, anywhase they stopped the test becuase it should signs of myocardial infarction, which is dead tissue in the heart. The man was apparently healthy except for the fact he had abused prohormones and had used clenabuterol extensively. Needless to say he is probably on a quick trip to living under the sod earlier than he expected. This is just a reminder to all about abusing these substances as they can be very dangerous.
