Epistane, EC stack and HIIT

[biff]

I just started a cutting cycle which consist of epistane, and was going to throw in an EC stack. I have become really fond of HIIT cardio latley, and was wonder if with the intensity of HIIT and the effects on blood preasure that the two compounds can have; would this be too risky? Should I just stick to low intensity cardio?

I'd really appreciate it if somebody could help me out with this.
