What is 'deer antler spray' and how does it help athletes? Elizabeth Cohen explains

Pro golfer Vijay Singh has admitted to using "deer antler spray," a substance meant to enhance athletic performance that is advertised as containing a hormone called "IGF one."

The performing enhancing substance, which is banned by both the PGA tour and the World Anti-Doping Agency, has been linked to the Ravens player Ray Lewis and the Alex Rodriguez scandal in reports this week.

In a statement, Singh admits to using the spray, but says that "at no time was [he] aware that it may contain a substance that is banned under the PGA tour anti-doping policy."

CNN's senior medical correspondent Elizabeth Cohen explains what the substance is and how it's used by athletes on Starting Point this morning.

    Regarding Senator Grassley's take on gun control – he believes that we should not do background checks so that relatives can trade/sell guns to each other on Sundays rather than waiting until Monday when a check can be performed. Is he crazy and that out of touch? These are the people who are passing laws in Washington? Does he not realize that some of those relatives trading and sellings guns could be criminals? Why do they always assume that only inner city individuals who trade and sell guns are criminals. Also, he brings up the mental health of the Newtowm shooter. Why didn't he bring up how irresponsible it was for his mother as a gun owner to leave her guns in the open for her mentally unstable son to practice with and to use. These politicians need to go back to school and study the 2nd amendment. It was not about individuals. IT was about arming against the mother country – England!!! Get it straight.
