As deer antlers grow, they're covered with a fuzzy layer called velvet, a substance rich in antioxidants and the growth hormone IGF-1. Believed to support cell growth, the velvet's compounds are extracted and bottled into this spray with ingredients such as L-arginine and tribulus. Taken sublingually twice a day, the spray may support muscle growth, aid recovery after intense workouts, and help users grow a fluffier white tail. Noticeable results usually take three to six weeks.
