I've got a friend who was a doctor in Mexico. He now lives in CA, and gets gear from Mexico. It is TT stuf that he said is made from chinese raw materials. He said he has lab tested what he gets. I have not done any of his TT stuff, but he uses it himself. He's very experienced with gear, and was my brothers good friend. So I gotta believe it's real.
Just my 2 cents.....
