Is it a good idea to stack Black Powder with NO2 Black?

I'm an 18 year old male trying to build muscle. I recently purchased NO2 Black (A bottle of 180 pills) and have been taking the recommended dose on the back of the bottle for 3 days. I was wondering if it is a good idea or a bad idea to still take Black Powder before i workout while i am taking these NO2 Black pills. Thanks for the help!Is it a good idea to stack Black Powder with NO2 Black?
