Juice will certainly increase blood pressure. When your off cycle and everything is cleared from your system, and you get your water retention down, your BP should become normal. What you can do, if there is no serious medical issue, is see your local health food store, a real one, the more reputable ones have naturopaths on staff. They can give you natural products that can eliminate that from happening again. There are arterial cleansing formulas, and herbal products that in the right combination will do the trick. After a Masters competition 2 years ago mine went to 165/100. Now even on cycle I don't go more than 126/76.and I'M 45 and my parents are predisposed as your are. There are products that do work trust me, I have been involved in bodybuilding and naturopathic medicine for over 20 years. By the way.....in your case make sure you avoid alchool while on cycle until your back to normal. If you PM me I can give you a specific guide what to ask for.
