LMAO "your own personal experience." Tell me stud, how did you isolate BCAAs as the agent of this "muscle preservation"? Please enlighten.
What I did was I have same diet, same calorie, same kind of workout and get my BF % taken. You can argue the method is not accurate. But based on those occasions, I got more muscle preserve if I took BCAA night before.
Of course, you can argue that if I took EAA or simply Whey, that will be the same. It will be the same argument like if Yates did the workouts like Ronnie, he would still win Mr. O and vice versa.
However When I took Whey, normally I get sleepy. So I took Whey post workout and not other times.
You can choose what to believe but I am just passing along what I found out. That might be bro-science but at least that is what works for me. Hence, " based on my own personal experiences"
