What is your normal blood pressure, and how high is it going up on cycle? My blood pressure is stable when off, but no herb, vitamin, supplement has been able to control it while on. I use a combination of vasotec+hctz right now, controls it perfect while on; seek physician advice if your blood pressure is not controlled below 135/85 IMO on cycle. Your using deca so you are going to be on for a long time, that can really damage your body.
