Deer antler spray use to be curtailed by MLBMajor League Baseball (MLB) has issued a warning to major and minor league players last week for stop ingesting deer antler spray.

It is being thought that some baseball players used to felt safe using a deer antler spray as an alternative to steroids with almost no risk of flunking a drug test.

From Sportsillustrated.cnn.com:

Deer antlers? Yes, chemists have figured out that the velvet from immature deer antlers includes insulin-like growth factor, or IGF-1, which mediates the level of human growth hormone in the body, and is also banned by MLB and the World Anti-Doping Agency, among others, for its muscle-building and fat-cutting effects.

The antlers are harvested from young deer, ground up and packaged into spray form. The substance is sprayed under the tongue. One manufacturer touts among its benefits “anabolic or growth stimulation,” “athletic performance” and “muscular strength and endurance.”

IGF-1, like HGH, cannot be detected in the urine tests used by baseball. Under the right circumstances, it could be detected in a blood test, but the players association has not agreed to blood testing.

The deer antler sprat was added by MLB to its list of “potentially contaminated nutritional supplements.”
