300mg Na-R-Ala and 2g ALCAR works perfectly fine, specially Pre-High-Carb-Meal.
Yes you can Mix the Na-R-Ala with Cit Mal , and some 20-30 mins later have the Gatorade if you so wish to. My suggestion would be a dosage like this:
-300mg Na-R-Ala , 2g ALCAR some 15-20 mins later and then around 20 minutes later a High Carb meal.
Or do the same but with 1g ALCAR and 2x a day.
