Hey dude, in all honesty I would mess around. You need to do bloods, etc. You might find your heart is damaged and taking a pill will mask the problem for now but you land up dead on the floor. Or your kidneys could be completely stuffed and you need something like xforge which helps the kidney function.
The costs to get it under control for some guys is just mind blowing. Discovery actually came to my work the other day and said listen we want to put you on the top plan because you paying 50k a year for 2 years over your current medical benefits. So I understand it's a massive expense.
You still young enough for your body to heal so itself so I would seriously consider working with someone. Not to be funny but at your age I would rather consider seeing a specialist, maybe a physician specialist. I can tell you now it's either your kidneys or your heart or you have some major plaque buildup. Hence the reason I suggested a physician specialist that you see once a year and you get your script repeats at your doctor.
Dude, blood pressure is a funny thing, if you had to start on a dose that i'm taking you will kill your self. You need to slowly slowly catch a monkey in this case and increase dose portion at a time.
Speak to your doctor and say you have heard wonderful things about Zartan 50, please can you try it. I am more than certain you will see a charge in your readings in 2 to 3 weeks. If not move up to coaprovel 150.
I also advise to stay away from gear until you have this problem sorted then when you do go back, go to safe steroids like Primo, which you can take pretty much any dose you like and you don't need to worry about major side effects, expect like DJ said (your hair)
Good luck bro. Phone now make a booking, get your script changed to Zartan 50
