Vijay Singh has withdrawn from the Waste Management Phoenix Open, one day after admitting to the use of deer antler spray, which contains a substance that is banned under the PGA Tour Anti-Doping policy.
Deer antler spray contains the chemical IGF-1, a natural anabolic hormone that stimulates muscle growth.
Singh was recently named in a Sports Illustrated report about a sports supplement company, Sports With Alternatives to Steroids, in which the company claims to have provided products for athletes including Singh and Baltimore Ravens linebacker Ray Lewis. According to the story, Singh paid $9,000 for the deer antler spray and other products in November.
In the SI interview, Singh said he “used the spray every couple hours … every day.”
“While I have used deer antler spray, at no time was I aware that it may contain a substance that is banned under the PGA Tour Anti-Doping Policy,” Singh said in a statement Wednesday. “In fact, when I first received the product, I reviewed the list of ingredients and did not see any prohibited substances. I am absolutely shocked that deer antler spray may contain a banned substance and am angry that I have put myself in this position.”
Singh said that he has been in contact with the Tour about the matter and is fully cooperating. Tour Vice President Ty Votaw said the Tour is currently looking into the matter.
