Breeder's Edge® Get Him Going™ supports your male's sexual performance when he doesn't rise to the occasion. Get Him Going contains horny goat weed for libido, maca for vitality, ashwagandha and niacin for energy and overall reproductive health. Sarsaparilla root is known to reduce inflammation and support hormone regulation. Get him going and keep him going. For use in Dogs and Cats, I recently used this for about 5 days before collection and it worked well. I have had some great feedback from customers as well.
