I was at LAX a few weeks ago with a 5lb tube of Chocolate protein powder. They pulled me aside, swabbed the powder, tested it in a machine and also with liquids to see if the powder was anything illegal. The entire ordeal took an additional 30 minutes including a detailed frisk. If they find any illegal contraband, they won't just make you dispose of it, but it'll buy you a one way ticket into custody. No need to risk a charge over something so small and avoidable brother. That's just my personal opinion. I have family that work in for AA and he tells me of several stories of individuals who try to be clever and beat the system. Usually never works, play it safe man. Good luck.
