Dude what the hell That sounds soooo bad and burny. Are you sure you aren't just a masochist or trying to get someone to hurt themselves? Admittedly it would be rather amusing to get someone to try this out...
um...anything mentholated or minty is NOT safe to use. For external use only means for EXTERNAL use only!
An hour later its tingly, try tingly X 1000000000 when you first put it on and thats kinda how it feels. I tried it months ago, as i was bored. I remember nearly passing out though, :&
