Yes, I use the 2 together.
I'm dosing 1 scoop of ASGT and 6 Creatine Nitrate pills pre w/o and 2 pills post w/o.
I have dosed the Creatine Nitrate solo also and either way I get an amazing pump. It really is good stuff and the price on Nutra right now is pretty good.
I don't have a great response to creatine mono or creatine ethyl ester but this stuff really seems to deliver.
