Hi Mike. Good to see a long time member. "Just 150" is actually a good size dose. Your doc really has no reason to not start you on HCG at the same time. You're going to shut down anyway and it would make for less titrations down the road. Glad you feel better, placebo effect or not right! It really takes time for all the positive effects to occur so patience is necessary.
I would ask your doctor to switch you to a twice per week injection protocol where you split your dose in half and inject every 3-4 days. Essentially less injected at one time = less spike in E level. If you're carrying extra BF right now you'll tend to aromatize easier. This will help. Goal is to not have to use an AI whatsoever if possible.
When it comes to BP take a look arginine to help:

Also consider asking your doc for low dose daily Cialis at 5mg x 2 per day. Not for issues downstairs but it's actually one of the healthiest things a man can take and will again help to lower blood pressure.
