First thing I would do is check your blood pressure. Androgens can raise BP. Make sure you keep an eye on BP through your cycle. If this BP related so early in the cycle, I don't think that it is estrogen related, so more AI probably will not make a difference. If you find that you consistenly suffer from high BP while taking gear, you might be best to use a BP medication. Norvasc and Toprol are two very common BP meds that can be used at low doses with few to no sides .I use toprol when my Bp gets out of hand. Long term, untreated BP issues can cause kidney problems. This is one of the most common health problems that bodybuilders suffer from. Too many guys have destroyed their renil function and it could have been avoided, just by keeping a closer eye on things
