C'Mere Deer® is a secret blend of plant and root extracts "synthesized." The formulation is as unique by design as are the results. Not only has extensive research gone into which plant and root extracts deer prefer, but how to blend them so deer will desire them.

A general tip: Anything claiming to be a "secret blend" is a load of bull.

The only thing with a ''secret blend'' that I endorse is my own BBQ sauce recipe.
