The guy above is right; any steroid can increase your BP. Usually it's more with drugs that have water retention. Even a supplement like creatine can increase your BP slightly, which is not an issue for most people coz our BP will still be within the normal range.
It depends on your BP range? If you have really high BP you shouldn't be using any steroid in the first place.
As for liver, i personally would say it doesn't matter because no matter what you use, you have to use the drug for short term and within the normal dosage. Say dbol at 40mg for 4 weeks would be ok. Yes it will increase the liver toxicity but no damage will be done. However, if you use it for say 10 weeks things can get ugly. The sad part is we are all different with different genetic makeup so in some people even 40mg at 4 weeks can cause serious liver issues, you will just have to try it out and hope all goes well. Regular blood work is the key. I get mine done every 3-4 months whether i am on or off cycle.
