Does the PGA Tour test for steroids? Banned substances for pro golfers
The PSG Anti-Doping Program is quite explicit about which substances are prohibited and the rules on testing players.
In any professional sport you are going to find cases of covert doping. Recently cyclist Jan Ullrich got his doping confession off his chest, telling Stern “I doped. I came into contact with it in 1995, 1996, before the Tour de France. I was young and naive and came into an existing system. The widespread perception at the time was that without assistance it would be like going into a gunfight armed only with a knife. The general attitude was: how are you going to survive in a race if you don’t take it?”
DeChambeau’s diet
The practice even extends to perceptively less strenuous activities like golf. Eyebrows were raised at Bryson DeChambeau’s striking physical transformation at the 2020 US Open. Looking decidedly brawnier, DeChambeau gained 9 kg of muscle mass in three months and claimed it was down to a high protein diet which consisted of consuming 3,000-3,500 calories per day.
Golf Hall of Fame member Vijay Singh admitted using Deer Antler velvet extract spray, which contains an anabolic insulin-like growth factor 1 (IGF-1) which was then a banned substance on Wada’s prohibited list. He was later cleared.

In 2016, Rory McIlroy highlighted how easy it is to find a way around the PGA Tour’s anti-doping controls: “I could use HGH (human growth hormone) and get away with it. So I think blood testing is something that needs to happen in golf just to make sure that it is a clean sport going forward.”.
The Anti-Doping Program was established in 2008 - nine years after the World Anti-Doping Agency (WADA) came into existence, in order “to protect the integrity that is inherent in the sport of golf and to ensure the health and safety of all players”.

How does the PSG Tour test players for banned substances?
All players who take part in a PGA Tour event may be required to undergo a doping control in which urine and blood samples are taken and tested. The tests are conducted by Drug Free Sport on behalf of the PGA Tour. Players may be selected for testing at any time or place, both inside and outside of tournament competition. Players do not receive prior warning that they will be summoned to take a test.
Samples analyzed by labs are identified by code numbers and not players’ names. If the sample is negative for a prohibited substance, the player will usually receive notification within three weeks from the Program Administrator.
If the sample tests positive, the Program Administrator will conduct an initial review to determine whether the player has an approved Therapeutic Use Exemption (TUE) for the particular substance found in the sample. If the initial review supports the finding of a potential violation, players may be required to provide further samples.
Players may obtain a TUE for the use of a prohibited substance as long as it does not produce any additional enhancement of performance. However, prior to a TUE being granted, a player who uses a substance on the PGA Tour Prohibited List runs the risk of being denied a TUE.
Eight players have been suspended since the PGA Tour launched its anti-doping program in 2008 - the most recent being Byeong Hun An who was hit with a three-month ban in October last year after a doping control detected a banned substance found in cough medicine sold over the counter in South Korea.
