Here is what they claim on their website.
""""""""""""""""""""""""""""""Turn up your game with Rack Snack and enjoy your herd and eliminate cull deer. Promote better racks and over all health of the whole herd."""""""""""""""""""""""""""
No offense but if you actually believe that bogus claim then another phrase comes to mind. """' A fool and his money"""
And please dont take my post the wrong way, when it comes to believing bogus claims from commercial mineral supplements I have been that fool many times. The truth of the matter is the only reason deer use our mineral supplements is because of the increased need for salt in their diet from April thru mid Sept. Pike
