120/80 is normal,had mine checked yesterday it was 135/80 I have had it at 170/110,cut out caffeine for a day and all stimulants Clen,Eca,ephedrine etc if you are taking it.Then go get it checked early the next morning before breakfast,then when you get the results take it from there.
Before going and getting blood pressure meds,try cutting out all sodium,cut out all stimulants,do 20 mins of cardio daily take 150mg aspirin daily.Then after a week get your BP checked again.
Stick to a good training program with cardio,clean diet,supplements,niacin is good for lowering BP it dilates the blood vessels therefore reducing the pressure.Dont start any drug cutting cycle until your BP becomes normal,get your BP checked every week.Dont drink alcohol and dont smoke if you do!
Try and normalise this situation without drugs,if all else fails,see the doc,it worked for me
