none of those supps do anything for bp, i even think in the post where potassium was recommended i said that the stuff does little for it. the only things that lower bp are usually the prescription meds, weight loss, change in diet, stopping aas, cardio. your doing most but it's not enough. take a hint, the drugs are telling you something. i had the high bp from gear. the only thing that worked was dropping weight and the gear and starting over and finding what was wrong. in my case i was 220 at 5'5". too heavy and the gear was killing me. changed everything and my bp is always normal now (i still monitor it on a near daily schedule).
supps will not control bp, it's not like cholesterol. you'll need prescription drugs if you come off the gear and drop the extra weight you may have and the bp is still high. get a home monitor and keep a daily log, take 2 measurements at once 10 minutes apart 3 times a day, get an average. if your high all day, go to the doctor.
