It depends on your goal and your diet structure.
My goal currently is fat free muscle in a progressive state hence my current set up.
But if your goal was to go for sheer size and gaining then Iād do it on all workout days pre workout only and work up to pinning pre-workout meal and then again pre-workout and using intra carbs.
If you still hit a ceiling then could introduce post workout, but again would heavily limit my fat intake these days to trace fats and keep 4-6 grams of omega 3ās in.
Thatās what I personally would do though as I like minimizing fat gain. Many others do it differently and more aggressive.
This thread and my last post should be in my all things insulin thread. Lol I cover it all there and goes along with it.
