The Use of Finasteride Among Athletes: Risks and Benefits
Finasteride, also known by its brand name Propecia, is a medication primarily used to treat male pattern baldness. However, it has also gained popularity among athletes for its potential performance-enhancing effects. In this article, we will explore the risks and benefits of using finasteride in the world of sports.
What is Finasteride?
Finasteride is a type II 5-alpha reductase inhibitor, meaning it blocks the conversion of testosterone to dihydrotestosterone (DHT). DHT is a hormone that is responsible for male pattern baldness, but it also plays a role in muscle growth and strength. By inhibiting DHT, finasteride can potentially increase testosterone levels and improve athletic performance.
Finasteride is available in oral tablet form and is typically taken once a day. It has a half-life of approximately 6 hours and reaches peak plasma concentration within 2 hours of ingestion (Kaufman et al. 1998). This means that it is quickly absorbed and metabolized by the body.
The Risks of Using Finasteride in Sports
While finasteride may seem like a promising performance-enhancing drug, it is important to note that it is banned by most sports organizations, including the World Anti-Doping Agency (WADA). This is due to its potential side effects and the unfair advantage it may give to athletes who use it.
One of the main concerns with finasteride use in sports is its potential to mask the use of other banned substances. Finasteride can lower levels of DHT, which is a marker for steroid use. This means that athletes who use finasteride may be able to pass drug tests for steroids, even if they are using them (Kaufman et al. 1998). This poses a serious problem for maintaining fair competition in sports.
Additionally, finasteride has been linked to several side effects, including decreased libido, erectile dysfunction, and gynecomastia (enlarged breast tissue) (Traish et al. 2011). These side effects can have a negative impact on an athlete’s physical and mental well-being, ultimately affecting their performance.
The Benefits of Using Finasteride in Sports
Despite the risks, some athletes still choose to use finasteride for its potential benefits. One of the main reasons is its ability to increase testosterone levels. Testosterone is a key hormone for muscle growth and strength, and by inhibiting DHT, finasteride may indirectly increase testosterone levels (Traish et al. 2011).
Furthermore, finasteride has been shown to improve muscle recovery and reduce muscle fatigue in animal studies (Traish et al. 2011). This could potentially give athletes an edge in their training and performance.
Another potential benefit of finasteride use in sports is its ability to prevent hair loss. While this may not directly impact athletic performance, it can have a positive effect on an athlete’s self-esteem and confidence, which can ultimately improve their performance on the field or court.
Real-World Examples
One notable example of finasteride use in sports is the case of American sprinter Justin Gatlin. In 2006, Gatlin tested positive for testosterone and was banned from competing for four years. However, he claimed that the positive test was due to his use of finasteride for hair loss (Associated Press 2006). While this claim was never proven, it highlights the potential for finasteride to be used as a masking agent for other banned substances.
Another example is the case of former NFL player Julian Edelman. In 2018, Edelman was suspended for four games for violating the NFL’s policy on performance-enhancing drugs. He later revealed that he had been taking finasteride for hair loss and did not realize it was a banned substance (ESPN 2018). This case shows the importance of educating athletes about the risks and regulations surrounding finasteride use in sports.
Expert Opinion
While finasteride may have some potential benefits for athletes, the risks and ethical concerns surrounding its use cannot be ignored. As a researcher in the field of sports pharmacology, I believe that the use of finasteride in sports should be strictly regulated and monitored to ensure fair competition and the safety of athletes.
Furthermore, more research is needed to fully understand the effects of finasteride on athletic performance and the potential long-term consequences of its use. Athletes should also be educated about the potential risks and side effects of finasteride, and the importance of adhering to anti-doping regulations.

Conclusion
In conclusion, while finasteride may have some potential benefits for athletes, its use in sports is highly controversial and poses significant risks. It is important for athletes to be aware of the potential consequences of using finasteride and to adhere to anti-doping regulations. As researchers, it is our responsibility to continue studying the effects of finasteride on athletic performance and to educate athletes about the potential risks and ethical concerns surrounding its use.
