My experience over 8 cycles. I will get some flaming I am sure but enough experience is under my belt and having walked the path....... Let's talk about blood pressure.
1. The absolute least respected item with AAS is Estrogen. Without beating a dead horse Adex is inferior to Aromasin unless you are running over a gram of substance. Aromasin due to its Estrogen killing nature allows you to go as low as possible without worrying about bottoming out. If you are truly trying your best to control BP grab some Aromasin. 25-50 mg a day will not bottom you out and leave you as low as possible on the Estrogen level. Low estrogen = Low water retention = reduced blood pressure and reduced sides causing the blood pressure increase. I put this as the absolute number one item dealing with blood pressure.
2. Water intake does not technically reduce blood pressure. It does play into a lot of areas that impact the vascular system. Primary one is Salt. Salt = Water retention = Blood Pressure up.
3. If you wanted to medicate Lisinopril is the cheap and efficent path. One 10 mg pill a day will drop you 10-20 on the systolic. It works.
The one thing I would stress is you are week 3. Test level is raising and from my experience transition of hormone level will reflect in blood pressure for anyone.
