I'm still concerned that your doses are timed too close together. I'm thinking it might be better to take it post workout, and then again in the evening. Rather than before and after workout. Remember this is only for your "maintenance phase" Loading phase is another ball game, you got 3 to 5 doses to manage throughout each day for 3 to 5 days.
In fact, I definately suggest doing the pwo dose, and evening dose cycle. I think you'll get much more out of it this way during your workouts, and throughout the day. BTW, be prepared to wake up in the morning with raging wood, and a bladder ready to explode.
or maybe thats just me
On another note.......
Your protein/carb ratio isnt correct..... Post workout should be 0.8g of carbohydrate and 0.4 g of protein / kg of body weight. Divide carb and protein grams in half for all other doses. Remember 1kg = 2.2 lbs
