This. I had to come off TRT a year ago due to feeling like crap from BP spikes as well. Was doing 100mg/week fwiw. Nailing macros and trying to nail all the required micros to see how that changes but wasn't able to figure it all out as I had other issues going on as well. So went off and still had higher then I need BP. Started experimenting with salt and started doing 7-9g of salt/day with my food and some in water. And BP went down pretty much instantly to sub 110/70s. So now I'm very curious if this trick would have helped me to control BP while staying on. I'm pretty much scared to start because I felt so so for a long time after all this "experiment" and def should have done a proper PCT. So anyway yeah salt/hydration/electrolite balance is absolutely crucial to main good BP and also lots of cardio, activity, learning things, hiking, nature, sun, etc, and ofc training/working out religiously .
