Considered an alternative to steroids with little risk of failed test

Baseball players in both the major and minor leagues have been warned to stop ingesting deer-antler spray, according to a story first reported by Sports Illustrated and confirmed by the New York Times.
Deer-antler spray includes "potentially contaminated nutritional supplements" and has been added to MLB's list of cautionary substances.
The warning is about a particular brand of deer-antler spray.
Until last week when the league issued its warning, players had apparently felt safe using the spray, administered under the tongue, as an alternative to steroids with little risk of failing a drug test.
Velvet from immature deer antlers, ground up and used in the spray, contains IGF-1, an insulin-like growth factor with "muscle-building" and "fat-cutting" effects.
IGF-1 is considered a performance-enhancer because it mediates human growth hormone levels in the body, but is not detectable by a urine test.
The players' association and the league have not agreed on blood testing, but under the right circumstances, SI.com reports, the chemical could be discoverable.
According to reports issued by the drug-testing industry, deer-antler spray can lead players to test positive for methyltestosterone, a chemical not listed as an ingredient.
Methyltestosterone is banned by both major and minor league drug policies and the World Doping Agency. It is used clinically to treat men with testosterone deficiency and women with breast cancer or symptoms related to menopause.
The spray had been endorsed by NFL players until recently, and its manufacturers claim it boosts "anabolic or growth stimulation," "athletic performance" and "muscular strength and endurance."
