LMFAO Press, jump lead kit. Let me find out you’re using those things off label over there in the UK

I'll give ya some expert knowledge here buddy Lol Both Losartan and Telmisartan work in the same way at reducing BP by relaxing arteries and allowing them to become wider effectively. They do this in the artery that supplies the kidneys which effectively reduces internal BP within the kidney, meaning the pressure at which the blood goes through the filters is reduced so it means the tiny holes don't become any wider or larger, which in turn means that things like protein, glucose, blood etc do not enter the urine and get pissed out. Things stay where you want them to. BUT if you actually look in your bloodwork next time you will see generally that your eGFR actually reduces because the blood flow pressure and therefore filtering is at a slower rate - this would lead you to believe that your kidneys are declining in function which isn't actually true. Its just a temporary decline in eGFR and this number will rise again once you come off the BP med. But the positive in taking them is they protect your kidneys while BP is effectively higher during a steroid cycle.

Normal and proper protocol when you get on an ARB or ACE inhibitor under a Doctors supervision and script, is that you get Bloodwork done after 2 weeks of using it, as some peoples kidneys can actually fail and decline rapidly because the internal BP can become too low for the kidneys to work properly. So guys buying them from sources is actually very dangerous in theory, but I guess you would know pretty quick if this happened to you as your urine output would suddenly become very low or stop. So I guess the answer is to only take BP meds if you really need to - don't take them if your BP is still fine/low on cycle.
