I have high BP naturally, it runs in my family.
For me, a healthy diet and regular cardio are vital or I will require meds to stay at 120/80.
If I add AAS like high dose tren to that, I will need meds too.
I currently take Lisinopril, I think it is something that every serious AAS user should talk to their doctor about. It is very tolerable, effective, and kidney protective.
If you can manage to go without BP meds, that is great, but for me that would mean perfect diet, daily cardio, and low dose or no heavy androgens.
I had some success with these natural remedies:
Magnesium Taurate - has other benefits as well
Grape seed extract - great anti-oxidant too
Celery seed extract - incredibly effective at lowering BP
Potassium citrate - another heavy hitter when it comes to lowering BP.
When I was taking them religiously, I was able to stay in healthy range while on cycle, but Lisinopril was just easier and a little more effective, so I went with that.
