post workout cardio

[DrGonzo]

I've always done some kind of short post work out cardio, like a session of hit or run sprints for 20 mins. I'm taking aas... test-e and deca atm, I'm not to sure if post work out cardio is the best idea. Would it be better for me to do cardio for a longer period of time on an off day or is a 20 min hitt session okay?
