Want to harvest the buck of your dreams? Use Trigger, a ready-to-use cream made with synthetic estrogen that mimics a female's ovulation. To create this high-quality cream, we collected the yellowish ovulation cream (natural estrogen) from a vibrant female elk before she was inseminated. The cream was then reproduced in the lab to perfectly mimic the scent a male seeks during rutting season. The quality of the product will convince you to use it year after year. It's very simple to use. The cream can be added to a urine pad, sex lure pad, or synthetic urine pad.
