What does intermittent fasting have to do with AAS? Hint: nothing really.
I use IF any time i cut as it helps me control calories as i have a set feeding window and won't snack outside of it. Since the key to any diet is to hit your macro/calorie goals IF functions much like any other diet. It's not like IF has any detrimental effect on AAS use. Granted, for optimal muscle gains we want to spread our protein intake throughout the day, but an 8 hour feeding window is fine. I highly doubt you would ever see any type of physiological difference between a group using a traditional diet vs a group using IF (both being on test). Don't over-think it.
