IDK if you have a supplement budget, but if you do:
Prioritize creatine and BCAA over protein powder, in favor of protein from food. That creatine and BCAA will supplement the food better than protein powder.
Don't get me wrong, if you can afford protein powder ALSO, then go for it.
Actually, even before that, add some beta-alanine.
Basically, I've come to the conclusion that the old-timers were consuming such "copious amounts" of whole protein per day to get certain amounts of creatine, BCAA, and beta-alanine. Now that we now about those substances and what they do (in TRAINED individuals), maybe normal people (not pro athletes or pro BB) don't need 300 grams of protein per day, so long as you're getting those targeted nutrients (and a normal amount of whole food).
