I have done both in the past, and in my experience from BCAAS I got a ton of weight loss each night, and noticably leaner almost every morning, but lost a lot of muscle mass, still.
When using Micellar at about 40 to 45 gs of protein, I didn't notice the rapid weight loss as much, but I did lean out slowly and seemed to retain more fullness.
So I'm at 220 from 225 now, leaning out a and trying both. 20-25 grams of actual protein an hour after zma, as I put my head on the pillow, and then 5 grams of BCAAS in the bathroom by the sink so when I wake up, inevitably, to relieve myself I take them in middle of the night. This is working like a charm. Good balance of fullness and leanness. And then 5 gs of BCAAs immediately upon waking. This regime is running about 50 dollars for six weeks worth of supps. Message me if you need any details or have questions.
