I don't think it is for human consumption. That stuff is $30 a quart.
That makes is about 8 times as costly as regular motor oil that comes in the same sort of container, LOL, or about the price of 200 lbs of corn.
I see where they claim 9 independent studies have proven that the stuff works. There are millions of independent studies that prove plain corn works.
I am sure hogs eat the stuff and if you have hogs and put that out, I am sure they will eat it just like they would do with corn. If you don't have hogs already, they aren't likely to magically appear because you poured out $30 of product on a tree stump or the ground.
