First off, unless you have 13-14" arms, you cannot fully trust the "drugstore" auto bp checkers. Go to any dr's office, or fire station with emt and they will check for free, and it will be accurate. Then if it's still an issue buy a battery or electric bp checker with the 'LARGE' cuff. they are about $30-$50, but very worth it if you have bp issues.
I had the same problem only it was a d.bol only cycle. BP went sky high, had severe headaces, etc.. Tried all the natural remedies, with no luck, and finally went to dr. for prescrip meds. That actually (for whatever reason) made it worse. I backed off the d.bol for two weeks, went back on and started drinking 1-1/2 gallons of water in addition to other liquids, shakes, etc.. My bp went down just a little, but the headaches subsided about 80%. The highest bp during my last cycle was like 179/112, and the lowest at night resting before bed was like 158/100. I just dealt with it, was a little more than nervous, but it just seemd that the d.bol was forcing the issue, and nothing was going to change it. Everyone is different, but that's what happened to me.
Go get it checked at an accurate station, and go from there. Good luck bro!
