Just took one of these Xedra Cut Lava sticks as an aid to Xedra Cut XT, as I am in the procces of getting lean and trim. USN Xedra-Cut Lava Sticks Well, it blew my head off, broke out in hives all over my head, face, neck, arms. Needed to take an anti-histamine. Emailed the company and the guy said it did the same to him as well, but it should be sipped over half an hour with plenty water too, not downed (like I did). This would be an awesome thing to stick in your camelbak on a long cold tab, serious thermogenic reaction. Now I feel like hitting the tackle bags hard, got a proper boost off it.
