38 yr old male..I ve been on test therapy (cypionate) since June 2013. Heart palpitations started in January. Could this be the cause? I also have been using rogaine foam since the summer. Could this cause it? Went to a cardiologist, took all the tests( stress, ekg, Halter monitor) and he said the palpitations I have are nothing to be alarmed about. He feels I should stop taking test. My test level is about 600 now, used to be 89. Im given 130 units of the T once a week( injections) I m not a bodybuilder.
