TestE and Dbol come with a great deal of water retention, especially when used without an anti-E. Most likely, your excess water retention is causing the spike in blood pressure. For starters, I suggest the following to get your water retention under control:

1. Start Nolva or Arim. I don't know your doseages so I can't suggest how much.
2. Drink no less than a gallon of water a day.
3. Eliminate sodium from your diet to the absolute best of your ability.

These are easy fixes that can be tried before introducing BP meds.
