Well if anyone is interested in the research I've done so far. Clenbuterol is shown to cause left ventricular hypertrophy in rats over a 3 week period. Left ventricular hypertrophy is caused by athleticism in Humans and requires no treatment. Their is criteria for this condition that can be measured with a simple ECG which i'm sure there are bodybuilders out there whom have had one after having had a clenbuterol cycle.
Hopefully someone will post an experience.
