Being a long-time ADer, I have experimented with pre-workout CHO (carbs), as well as post-w/o CHO, and of course the AD wherein you keep CHO to a minimum.
While I have found my muscles to certainly stay fuller with CHO, IME it is not as effective as the true AD unless I have specific goals.
Pre w/o on the AD, I generally do 50g protein powder, and some amino acids. Post workout, when gaining mass I used olive oil generously, doing roughly 12 tbsp along with another 50g protein powder. Now, while cutting down, I have been doing amino acid pulses, not entirely dissimilar to what some of the fellows on the BCAA Megadose thread are doing. This has worked tremendously well for me.
