Here’s the thing. The AD is aimed at suppressing large insulin spikes for a 5 day stretch. If at any time you take in a large amount of fast acting carbs you are creating a large insulin spike. This interferes with the overall plan of regulating your hormones.
Having said that, If you have been on the basic AD plan for ~ 3 months, and truly feel the need for PWO supplements like Surge during the week due to fatigue late in the week or consistent drops in performance, then go ahead, but try and keep it under 30gm total.
From Bulgarian (a bb’er on the AD):
if you are not cutting, just increase the amount of protein you take in. If cutting, take small amounts of BCAA’s+Whey peri-workout.
