Semaglutide: A Therapeutic Option for High-Level Athletes
In the world of high-level sports, athletes are constantly seeking ways to improve their performance and gain a competitive edge. While training, nutrition, and genetics play a significant role, the use of performance-enhancing drugs is also a prevalent practice. However, with strict anti-doping regulations in place, athletes must be cautious about the substances they use. This is where semaglutide, a relatively new drug, comes into play as a potential therapeutic option for high-level athletes.
The Rise of Semaglutide
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist that was initially developed for the treatment of type 2 diabetes. However, its potential as a performance-enhancing drug has recently caught the attention of the sports world. In 2019, the World Anti-Doping Agency (WADA) added semaglutide to its list of prohibited substances, classifying it as a metabolic modulator. This means that the use of semaglutide by athletes is strictly prohibited both in and out of competition.
Despite its prohibited status, semaglutide has gained popularity among high-level athletes due to its potential benefits. It has been reported to increase muscle mass, improve endurance, and aid in weight loss. These effects are particularly appealing to athletes who compete in sports that require strength and endurance, such as cycling, running, and swimming.
Pharmacokinetics and Pharmacodynamics of Semaglutide
Before delving into the potential benefits of semaglutide for athletes, it is essential to understand its pharmacokinetics and pharmacodynamics. Semaglutide is administered subcutaneously and has a half-life of approximately 7 days. This means that it remains in the body for an extended period, making it a convenient option for athletes who need to undergo frequent drug testing.
As a GLP-1 receptor agonist, semaglutide works by mimicking the effects of the naturally occurring hormone GLP-1. It stimulates the release of insulin, which helps regulate blood sugar levels, and also suppresses the release of glucagon, a hormone that increases blood sugar levels. Additionally, semaglutide has been shown to slow down gastric emptying, leading to a feeling of fullness and reduced appetite.
Potential Benefits for Athletes
One of the main reasons why semaglutide has gained popularity among athletes is its potential to increase muscle mass. Studies have shown that semaglutide can stimulate the growth of skeletal muscle cells, leading to an increase in muscle mass and strength. This effect is particularly beneficial for athletes who need to maintain a high level of muscle mass, such as bodybuilders and weightlifters.
Furthermore, semaglutide has been reported to improve endurance in athletes. This is due to its ability to increase the utilization of fat as an energy source, leading to improved performance during prolonged exercise. In a study conducted on mice, those treated with semaglutide showed increased endurance and improved running performance compared to the control group.
Another potential benefit of semaglutide for athletes is its ability to aid in weight loss. As mentioned earlier, semaglutide can suppress appetite and slow down gastric emptying, leading to reduced food intake and increased feelings of fullness. This can be particularly beneficial for athletes who need to maintain a certain weight for their sport, such as boxers and wrestlers.
Real-World Examples
The use of semaglutide by athletes has already made headlines in the sports world. In 2020, Danish cyclist Jakob Fuglsang was suspended for four months after testing positive for semaglutide. Fuglsang claimed that he was prescribed the drug for medical reasons and was unaware that it was prohibited. This incident highlights the need for athletes to be cautious about the substances they use and to always consult with a medical professional before taking any medication.
On the other hand, some athletes have openly admitted to using semaglutide as a performance-enhancing drug. In an interview with ESPN, American professional cyclist Phil Gaimon revealed that he used semaglutide to aid in weight loss and improve his performance. Gaimon stated that he was aware of the risks and potential consequences of using a prohibited substance but was willing to take the risk for the sake of his career.
Expert Opinion
While the potential benefits of semaglutide for athletes are promising, it is essential to consider the potential risks and side effects. As with any medication, semaglutide can cause adverse effects, including nausea, vomiting, and diarrhea. Additionally, the long-term effects of using semaglutide as a performance-enhancing drug are still unknown, and more research is needed in this area.
Furthermore, the use of semaglutide by athletes raises ethical concerns. The use of prohibited substances in sports goes against the principles of fair play and can give athletes an unfair advantage over their competitors. It is crucial for athletes to prioritize their health and well-being and to compete fairly without the use of performance-enhancing drugs.

Conclusion
Semaglutide has gained popularity among high-level athletes due to its potential benefits in increasing muscle mass, improving endurance, and aiding in weight loss. However, its use as a performance-enhancing drug is strictly prohibited by WADA, and athletes must be cautious about the substances they use. While the potential benefits of semaglutide are promising, it is crucial for athletes to prioritize their health and well-being and compete fairly without the use of prohibited substances.
