Currently on week 6 of my 1st cycle, regular test e cycle, copied from Austenite's My First Cycle: Planning and Executing a Successful First Cycle

week 1-12: 225 mgs testosterone enanthate every 3.5 days
week 1-14: 0.5mg arimidex every 3.5 days
week 1-14: 300 ui HCG every 3.5 days

I'm also on finasteride (1mg ed) and accutane (20mgs ed).

Supplements: weekly B12 shots, multivitamin ed, Vit C ed, BCAA peptides morning and after workout

Cycle has been great, I'm up 12-13 pounds. Crazy strenght gains, crazy pumps and overall my body feels totally different. Also loving the new sex drive lol.
I'm 38 and all my life have been lifting weights, sometimes a bit off as life goes on but always considered my self a bodybuilder at heart. Never been on AAS, my prime was in my mid twenties maybe I can get back there .

Side effects I only feel the bloat the day before taking adex, so i am considering taking it eod. Also sex drive lowers a bit past the adex half life.

Last chest workout, started to feel a headache during the workout, but as I was in the beach for a while before the workout thought it was due to it, sun and all. Yesterday, started shoulder press and mid my 1st working set (heavy) got another severe headache. I almost never have headaches, most of the pain seems to be behind my right eye. Still continued the workout, but had to tone it down a lot, I like to train high intensity so it was a really bad workout .
Knew exactly what it was - high blood pressure -
All my life my blood pressure has been almost perfect 12-8. Today in the morning 15-9, during the high intensity sets probably spiked to values that got me the bad headache.
So, blood pressure is my first bad side effect from this cycle.

My doctor wants to prescribe me an ARB (Angiotensin Receptor Blocker) but I remember Bonaparte advising on ACE inhibitors. So what is the best drug to help on-cycle blood pressure?
