MLB warns players about deer spray…

Major League Baseball issued a warning to its players last week about a new substance that can make players test positive for methyltestosterone.

Methyltestosterone is a banned substance that has already been banned by the MLB but it doesn’t show up on the ingredients list for the deer-antler spray some players have been using.

The spray is applied under to tongue and is said to be an alternative to steroids because it has IGF-1.

IGF-1 is an insulin-like growth factor that the manufacturers say can cause¬†“anabolic or growth stimulation,” “athletic performance” and “muscular strength and endurance” as reported by ESPN.

According to the report, players had felt free to use the spray at nearly no risk until the warning was sent last week by the league.
