You have to be really careful on the scent product makers. I watched a documentary several years ago basically said no way can distributors have enough estrus does to fill tons of pee bottles. I know they can force estrus cycles but it would take a whole lot of deer to sell large quantities of bottled products. However, every year I do purchase Code Blue products, and Golden estrus I think is made by Wildlife Reshearch. Do I think it is fully as described no way, does it work, sometimes. Sometimes is better than never. Purchase what you believe helps you harvest.
