Do you have a large arm? Are you holding it straight, at heart level with legs uncrossed? For me I have to follow strictly the above protocol or I read high.
I wouldn’t be too alarmed about 145/85… It’s the second number (diastolic) that matters the most as I believe it represents the arterial pressure of blood flow BACK to the heart as opposed to away from the heart, which can cause more issues. On cycle the 170/100 is very high so good thing you stopped.
Bumping up the cardio a bit preferably intensity over duration would help bring it down and lowering caffeine/preworkout stuff if you use any would also lower it. But yeah that is a high BP score at just 200mg tren. Was it enanthate or acetate?
