I'll take a stab here...
I think your blood pressure raises only because of the water weight gain you get from the excess estrogen conversion from something like Test or Dbol. So if you're running alot of test, you may want to run an anti-e with it to combat the estrogen bloat. If your BP is already on the high side, you may want to keep an extra eye on it.
And the liver problems come more so from orals. So if you're not running Dbol or Drol your liver should be fine. In either event, you could take some Tylers or R-ALA or Milk Thistle to keep your liver in good shape through the cycle anyway.
