Ive never had deer scents work, it is said the stuff 'doe in heat'breaks down chemicaly after collected,in a short time ,cant bottle it fresh as you need it. Its best to have a deer smell NOTHING at all. But I buy it anyway,use it little now ,get my buck anyway too, but of no help from any urine/charcoal crap[Scentlok]/or other such crap, just dont move,wash with scentless soap,play the wind or stalk with stealth, its worked for many centuries.
