Dangerous taking steroids while doing jogging, kickboxing (Cardiovascular work)

[manwitplans]

Well, the question is in the title.
And which steroids would be the best to use?

The steroids are going to be used for increased musclemass, not increased stamina, and cardiovascularity.

I reccen using testo, without dbol, because of bloodpressure dangers while doing a good amount of cardio work, give me a hint.

No it is perfectly healthy to do cardio while on gear. What are your stats? And I am not sure what your last sentence is saying.
