I think of training like a card game. You aren't going to play your trump card first. If you do you get pooched later on.
If you play your trump card now what exactly are you going to do when you hit a plateau. Get your training and diet in order? Once your results slow down, make nutritional/training changes and keep going. When you are no longer able to sustain a decent rate of progress THEN you should consider some other supplements. Play your trump.
For now I'd just stock your cupboard with Metabolic Drive (a.k.a. GROW), Surge, and maybe some Flameout to help with inflamation and insulin sensitivity. And for the record...if your results slow after a month, you're doing something wrong.
