Arm cuff size can affect the BP reading a lot. I tested with my GF's family BP monitor and it came out at 190/100. LOL 'Bout shit myself. Took it next day with a normal cuff and it was 130/75 ish. You might need a bigger cuff.
Yeah, Tren makes your BP rise, generally. You should definitely check it again if you're worried. Honestly, that's a "normal' Tren reading, IME. (Doesn't mean it's good, just that I've seen legit 150's/80's in myself and others on Tren). So, it may well be accurate.
5-10mg a day of Cialis can cut that reading down pretty quick. With Cialis, after a week off Tren (not long enough to clear Tren E), I was at 115/65. Kinda low. Your results may vary.
