I would rather take them pre so as to take advantage of protein sparing, even (and especially) if dieting. The advantages are stacked so far in favor, stimulating insulin and esp in the presence of EAAs in free form, the results would amaze you
well ill add in this, which i believe all of us would agree on. pre-workout nutrition is well overlooked by many...thinking post workout intake is the only and primary "time-gap" to feed the body in prep/recovery for a workout. Where as, pre workout should go hand in hand with one's post workout nutrition.
1 hour before my workout, I have breakfast, which consists of 3/4 cup oatmeal, and 5 eggwhites, AA's, Glucosamine/MSM, and my Multi (containing B vitamins).
Then, about 15 minutes before workout I take V-12 (creatine), and more AA's.
During my workout I get some more AA's.
PW, I go with 40g protein, 44g carbs, and more AA's.
Then I continue to take AA's at every meal
