The VS-1 Stick is the only buck attractant that is vaginally extracted from individual does that are in the peak of their estrus cycle. Does are synchronized with hormones so they super-ovulate, resulting in a higher volume of pheromones. Each doe is then tested to ensure she is at the peak of her cycle. The vaginal secretions are then collected along with the pheromone-saturated urine, thus creating VS-1. The stick formula is recommended for wiping on both sides of three to four scent pads. Hang pads by scrapes, rubs and high-traffic areas during the peak of rut. When done hunting for the day, put scent sponges in a zip-loc bag to store. When returning to hunt, wipe fresh scent on the sponges. Leftover product should be vacuum-sealed to preserve freshness at the end of the year.
