Years ago when I was taking BCAA’s, the odd time I’d burp up a “powder”.
I’ve started taking BCAA’s again and noticed the SAME thing happening. I know it sounds odd, but man I don’t wanna be talking to people, burp and this gaseous powder comes out of my nose!!
I used to do that with the old blue TRIBEX, and it was pretty funny, but also disgusting. Never done it with BCAAs though, and I go through a ton of powdered BCAAs. Just gotta follow up with a lot of liquid. Capsules would probably be more likely to do this, too.
