I replied to the thread you started in the Plazma Users forum.
I still think the issue is that you're finishing your workout nutrition too soon, long before the workout is over, and waiting long after the workout to fuel up again.
You'll still build muscle fine, because you've gotten the protein and carbs into your system. Blood sugar shouldn't really interfere with that.
Yep. And make the during-workout nutrition last the whole workout.
