Yeah, I can tell you that this is an awesome combo. In my post shake I have creatine5g with 45g glucose, 40g protein, 4g arginine, 5g glutamine and a Pepsi. When I leave the gym I have the craziest pump going on its sick!
If I were you I would eat a fast digesting carb like glucose after training in your shake. You want to restore your glycogen levels as fast as you can and spike your insulin levels. Bro, try eating lots of sugars after training for a months or two. You will notice some nice gains. And as long as your training intensly you wont add bodyfat.
