OK
a little clarification of AAS and the immune system. The reason your immune system gets a little off when on is due to the fluctuation of hormone levels. Once they are balanced out (consistent levels in the blood), and your body has adjusted to them, it will increase your immunce system. When you come off, your immune system will again be lowered due to the fluctuating hormone levels. So:
Beginning of cycle: immune dysfunctions
Mid-end cycle: stronger immune system
post-cycle: weakened immune system (I know many get sick post cycle)
As for dosage of r-ALA, glutamine, and creatine:
creatine 5-10g/post workout with ample high GI carbs
glutamine 5g/before training, 5g/post workout, 10g/before bed
r-ALA really depends how you want to use it. I take 200-300mg with all higher carb meals. Definitely use 300mg/post workout to help shuttle all the above supplements into the muscle cells, and negate any excess carb intake from being stored as fat.
