Velvet antler in the form of deer antler spray has been at the center of multiple controversies with professional sports leagues and famous athletes allegedly using it for injury recovery and performance enhancement purposes. In mid-2011 a National Football League (NFL) player successfully sued a deer antler velvet spray manufacturer for testing positive for methyltestosterone in 2009 for a total amount of 5.4 million US dollars. In August 2011, Major League Baseball (MLB) added deer antler spray to their list of prohibited items because it contains "potentially contaminated nutritional supplements." 
Some people use deer velvet to increase levels of certain sex hormones (estrogen and testosterone), improve fertility, increase interest in sexual activity (as an aphrodisiac), and treat male sexual performance problems (erectile dysfunction, ED). Women use deer velvet to reduce the dose of estrogen they need in hormone replacement therapy. They also use it for menstrual and menopause problems, vaginal discharges, and uterine bleeding.
IGF-1 is currently on the World Anti-Doping Agency’s prohibited list due to how it gives athletes an unfair advantage in terms of building strength and muscle mass. (7) However, it’s still legal to use supplements that may provide IGF-1 or similar effects. Most of the studies that show positive results from using deer antler supplements have used high doses. And some have tested the product on animals (mice or rats) rather than humans.
One double-blind study published in the International Journal of Sports Nutrition and Exercise Metabolism tested whether or not deer antler velvet powder or extract had an impact on aerobic performance, endurance and “trainability of muscular strength” compared to a placebo. The subjects were adult males. They were given either a placebo, or deer antler extract or powder supplementation over a 10-week period while undergoing a strength-building routine. The men were measured for muscular strength, endurance, and VO2max before and after using deer antler. These results were determined by measuring circulating levels of testosterone, insulin-like growth factor, erythropoietin, red cell mass, plasma volume, and total blood volume.
