The only buck attractant that is vaginally extracted from individual does that are in the peak of their estrus cycle.We now have a collection process so unique to this industry that it is patent-pending. We actually synchronize does 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 our VS-1. There is no other Deer Scent product like it on the market today.We took the most powerful deer attractant ever and developed a solid stick patented process that encapsulates and protects the estrus pheromones until it is applied. When applied the capsules are broken open and the pheromones are released. The advantages are: ease of application, re-sealable container, no spilling or leaking, will not freeze and will not break down in temperatures under 100 degrees. Can be stored safely in a hunters backpack. The stick can be applied to almost any surface. This Patented stick formula will change the scent industry forever!VS-1 Stick DirectionsThe stick formula is recommended for wiping on both sides of 3-4 scent sponges. Hang sponges by scrapes, rubs, and high traffick areas during the peak of rut. It may also be used with Scent Trax for a dragline. When done hunting for the day, put scent sponges in zip-loc bag to store. When returning to hunt, wipe fresh scent to sponges. Left over product at the end of the year should be vacum sealed to preserve freshness.
