I havent ever used that exact product,so take my opinion with a grain of salt. Studies have shown that doe estrous loses certain characteristics just 2 days after being collected. How long was the stuff in a bottle before you bought it, even if it is this years? As for the Special Blend, what exactly do they blend? What i do think it may do is lure a curious deer to the scent, but it could have the reverse effect just as easily..... been there done that.
