Ah man thats a terrible feeling and there are a lot of guys who get sides from as low as 30mg of T. Plenty of them in the Taeians Clarks Deca only HRT group on the FB. I hope you overcome that damage and that is not permanent but I know the feeling. Since I got off cold-turkey about 8 months ago my original sex-drive and libido and errection quallity took a huge hit. I never was like this before. Always was spot on and now like a fucking switch. Still all works but need more play n shit, and always what it took was just a damn thought hehe So def something fucked up for me as well but I havent done any PCT and perhaps I'm even shutdown now on something as I haven't done any hormonal blood tests to see the outcome. I will try adding lots of fats to see if it improves and about fats you should also increase the fats esp when running Deca base HRT. That has a lot of benefits and is alot discussed in the "Camel Cult" HRT only group I've mentioned. Maybe you know it yourself, no idea 
Awesome that you keep a log. I do too for everything I do and thats probably 20 years long by now. Not only health related fwiw. A few weeks TBH means not much when dabbling with hormones and stuff and its tough to know if after those two weaks shit hit the fan and even without Test you would get BP spike or that was all fine and just after adding Test on top fucked it up going forward. The more moving parts the harder to work with and becomes a fucking riddle which in fact raises your BP because you are getting more anxious, etc, trying to figure it out. If you know what I mean.
After getting off TRT my BP still was elevated but declining slowly but not there I wanted it do be. I also have IG account where I follow around 5-6K people. Too fucking much and I was always scrooling and checking something that I should have never checked as I know what I need to know for ages and need no confirmation or whatsoever, if you get the drift. So after I deactivated my IG, few days passed and I felt absolutely cool, calm and collected, like a damn rock lifted my shoulders. Measured my BP, mid-day, usually when I have it elevated and it was beautiful, IIRC 116/76 with pulse preasure being perfect at 40 (systolic-diastolic 116-76=40). So I'm pretty sure that all social medias and the shit that we watch online absolutely impairs out wellbeing or at least it did mine and in an ugly way. Ofcourse that could have been a coincidence with something I have no idea about as maybe I got healthier while off TRT or something along those lines.
Sorry for a long rant but I'm just back from gym, working in the office and had to do it lol

p.s. oh and I forgot I also done a 500ml private venesection so maybe that also had something to do to lowering BP. My last VS was in 2019 fwiw.
