muscle loss on a cycle?

I have heard and read that during a cycle one can lose muscle if their cardio is to high or intese. wondering if their is any truth to this because i would like to drop my bf%. I will be running 750mg test enanthnate and fina on my next cycle. I know i will gain but dont want to hinder by trying to shed some fat. thanx

yes thereis truth to that ,onl id done too frequently ,but it mostlyoccurs when off cycle ,and doing excessive cardio.best is bulk then work on sheding it off not both,
