I don't think anyone is suggesting consuming BCAAs all day instead of food, though......
You beat me to it as I was typing the following:
Instead of strategic 10g here and there, it becomes 60g all day instead of natural sources. There is not substantual science to back back BCAA's being a superior way of injesting protein to regular meals. If youre after a pump, just focus on the pump and refuel on food after.
That's not what I was talking about, or what the OP was asking about, so it's completely superfluous to this discussion. No one here is suggesting talking about using BCAAs as a replacement for quality whole food and protein, only questioning if there is any benefit to be had from SUPPLEMENTING with BCAAs pre-workout, supplementing meaning as an addition to, not in place of, whole foods. Even if you don't think BCAAs taken peri-workout (ALL OTHER VARIABLES HELD CONSTANT, meaning diet is otherwise the same, so BCAAs are NOT REPLACING REAL FOOD) will provide any benefits, I fail to see how they could be detrimental to the vast majority of users, or how better progress would be made without them (if anything, progress should be either better, if they work, or the same, if they do not).
I also apologize for resting on assumptions of you having studied the efficacy of BCAA and the evolution of them over the last 25 years. When I started using them, I myself thought they were magic pills. Then there is the placebo effect... 25 years of head scratching...lol
Yes, because I've never studied BCAAs at all. Thank the Supplement Gods that you are here to teach me the error of my ways and enlighten me.
