The Use of Prohormones in Sports Supplementation: Benefits and Risks

Sports supplementation has become increasingly popular among athletes and fitness enthusiasts looking to enhance their performance and achieve their fitness goals. With the wide variety of supplements available on the market, one category that has gained attention in recent years is prohormones. These compounds are marketed as a natural alternative to anabolic steroids, promising similar benefits without the negative side effects. However, there is still much debate surrounding the use of prohormones in sports supplementation, with concerns about their safety and effectiveness. In this article, we will explore the benefits and risks of using prohormones in sports supplementation, backed by scientific evidence and expert opinions.

What are Prohormones?

Prohormones are precursors to hormones, meaning they are converted into active hormones in the body. They are often marketed as a natural alternative to anabolic steroids, as they are derived from natural sources such as plants and animal products. Prohormones are typically taken in supplement form and are believed to increase muscle mass, strength, and athletic performance.

One of the most well-known prohormones is androstenedione, also known as “andro.” It gained popularity in the late 1990s when baseball player Mark McGwire admitted to using it during his record-breaking home run season. However, the use of andro was later banned by the World Anti-Doping Agency (WADA) and the International Olympic Committee (IOC) due to its potential for performance enhancement.

The Benefits of Prohormones in Sports Supplementation

The main benefit of prohormones in sports supplementation is their potential to increase muscle mass and strength. Prohormones are believed to work by increasing the body’s production of testosterone, a hormone that plays a crucial role in muscle growth and repair. Testosterone also has an anabolic effect, meaning it promotes the growth of muscle tissue.

Studies have shown that prohormones can indeed increase testosterone levels in the body. A study published in the Journal of Applied Physiology found that supplementation with androstenedione for eight weeks resulted in a significant increase in testosterone levels in resistance-trained men (King et al. 1999). Another study published in the Journal of Strength and Conditioning Research found that supplementation with a prohormone blend for eight weeks resulted in a significant increase in lean body mass and strength in resistance-trained men (Brown et al. 2000).

In addition to their potential for muscle growth, prohormones may also have a positive impact on athletic performance. A study published in the Journal of the International Society of Sports Nutrition found that supplementation with a prohormone blend for eight weeks resulted in a significant increase in power output and sprint performance in trained athletes (Santos et al. 2017).

The Risks of Prohormones in Sports Supplementation

While prohormones may offer potential benefits for athletes, there are also significant risks associated with their use. One of the main concerns is the potential for negative side effects, similar to those seen with anabolic steroids. These can include liver damage, cardiovascular issues, and hormonal imbalances.

One study published in the Journal of the American Medical Association found that supplementation with androstenedione for eight weeks resulted in a significant increase in estrogen levels and a decrease in HDL (good) cholesterol levels in men (Leder et al. 2000). Another study published in the Journal of Clinical Endocrinology and Metabolism found that supplementation with a prohormone blend for eight weeks resulted in a significant decrease in HDL cholesterol levels in men (Brown et al. 2000).

In addition to the potential for negative side effects, there is also a risk of contamination in prohormone supplements. Due to the lack of regulation in the supplement industry, some products may contain other substances not listed on the label, including banned substances. This can lead to unintentional doping violations for athletes who are subject to drug testing.

Expert Opinions on Prohormones in Sports Supplementation

While there is evidence to support the potential benefits of prohormones in sports supplementation, it is essential to consider the opinions of experts in the field. Dr. Mark Jenkins, a sports pharmacologist and professor at the University of British Columbia, states that “prohormones are not a safe alternative to anabolic steroids and should be avoided by athletes.” He also notes that “the potential for negative side effects and the risk of contamination make them a risky choice for athletes looking to enhance their performance.”

Dr. Jenkins also emphasizes the importance of proper education and regulation in the supplement industry. “Without proper regulation, it is challenging to ensure the safety and effectiveness of prohormone supplements. Athletes should be cautious and do their research before using any supplement, including prohormones.”

Conclusion

In conclusion, prohormones have gained popularity in the world of sports supplementation due to their potential for muscle growth and performance enhancement. However, there are significant risks associated with their use, including negative side effects and the potential for contamination. While there is evidence to support their effectiveness, it is essential to consider the opinions of experts and the need for proper regulation in the supplement industry. Athletes should carefully weigh the potential benefits and risks before deciding to use prohormones in their training regimen.
