Personally, if I am training AM fasted, or a good 4+ hours after a meal, use EAA’s w/carbs intra workout. If I had a chance to eat an hour or so beforehand, I wouldn’t worry about it. The vast majority of my workouts are early AM so I have found they (along with intra carbs) make a big difference. If you train after a meal and get adequate protein intake over the day, you likely won’t see a huge difference.
Lots of great options out there.
Some ones I have used and thought were decent (off the top of my head):
Nutrabio Intrablast and AlphaEAA
Prosupps Hydro BCAA+ (has EAA’s)
Allmax MuscleEAA
Morphogen Synthagen
Beware formulas that are basically BCAA and pixie dust all of the EAAs.
