HOT-ROX Extreme and Coffee?

will I be able to drink coff while taking HOT-ROX Extreme? It doesn;t say one way or the other on the lable and it doesn’t give an amount of caffeine.

I have taken my HOT-ROX with coffee and have some great workouts, but I don’t think it’s a good idea in the long run. Once I stopped HOT-ROX with coffee, I lost 1 inch in my waist. I was probably overdoing it for too long.
