Tbol like any AAS can raise blood pressure and in some instances do so quite dramatically. Although this is more common with dbol and a-bombs, I have heard of these symptoms from things more mild such as winstrol and yes even tbol. I don't know if I'd totally stop taking it though. I think you might want to lower your dosage a bit and let your body adjust to it - 50 mgs might just be to high for you to start out with - but over time you'll likely be able to raise the dosage. Good Luck!
