RE: Code Blue Doe Estrus........any good?
I have also seen studies that say that if you buy "doe estrous urine", you are just buying plain doe urine. Due to the fact that the estrogen molecules evaporate within minutes of being exposed to air. I will have to do some research to find who done these studies, but, I know I read about them from a well respected research organization. I will start my search and let you know what I find.
