My family has used it since 1980. And we have plenty of mounts to prove it works... doesn't take much, rub a little on soles, arms, pants and never been busted. That's a fact! Was my number one seller when i used to have an Archery shop years ago. They still sell it, and you can find it on the net. You can substitute in a pinch with real Mexican Vanilla, but imitation kind doesn't work. Don't believe me research Russell Hull the inventor and see his trophy room...along with others who use it..
