Deer Antler Banned by Major League Baseball for Known Performance-enhancing Benefits

There’s another prohibited item that the Major League Baseball players have to be cautious of. According to Sports Illustrated, the warning for the use of deer antler spray has been issued because of the presence of a banned chemical that builds muscles and cuts fat.

Sports Illustrated’s report addressed the players, warning that the deer antler spray includes “potentially contaminated nutritional supplements”. The spray has been recently added to the list of products banned by the league. The chemical element the league is wary of is IGF-1, an insulin-like growth factor. Major League Baseball apparently said that using the spray may result in a positive test for methyltestosterone, which is a steroid.

According to, IGF-1 can be considered a performance enhancer because it mediates the level of human growth hormone. The league as well as the World Anti-Doping Agency bans performance enhancers.

However, chemical has not been detected in the tests done by the Joint Drug Prevention and Treatment Program.

Some of the highlighted functions of the spray are anabolic or growth stimulation, athletic performance, muscular strength, and endurance. These functions are highlighted by the manufacturers themselves.
