Athletes’ Side Effects of Methyltestosterone
Methyltestosterone is a synthetic form of testosterone, a hormone that is naturally produced in the body. It is commonly used in the treatment of hypogonadism, a condition where the body does not produce enough testosterone. However, it has also been used by athletes to enhance their performance and muscle growth. While it may provide short-term benefits, the use of methyltestosterone in sports comes with potential side effects that can have long-lasting consequences on an athlete’s health.
Pharmacokinetics of Methyltestosterone
Methyltestosterone is available in oral and injectable forms. When taken orally, it is rapidly absorbed in the gastrointestinal tract and reaches peak levels in the blood within 1-2 hours. It is then metabolized in the liver and excreted in the urine. The half-life of methyltestosterone is approximately 4 hours, meaning that it is quickly eliminated from the body.
When injected, methyltestosterone has a longer half-life of approximately 18-24 hours. This allows for a sustained release of the hormone into the bloodstream, providing a longer duration of action. However, this also increases the risk of side effects as the hormone remains in the body for a longer period of time.
Pharmacodynamics of Methyltestosterone
Methyltestosterone works by binding to androgen receptors in the body, which are found in various tissues including muscle, bone, and the brain. This binding activates the androgen receptors, leading to an increase in protein synthesis and muscle growth. It also has anabolic effects, meaning that it promotes the retention of nitrogen in the body, which is essential for muscle growth.
Additionally, methyltestosterone has androgenic effects, meaning that it can cause the development of male characteristics such as increased body hair, deepening of the voice, and enlargement of the clitoris in females. These effects are due to the conversion of methyltestosterone into dihydrotestosterone (DHT) in the body.
Side Effects of Methyltestosterone in Athletes
The use of methyltestosterone in sports has been associated with a range of side effects, both short-term and long-term. These include:
- Increased risk of heart disease and stroke (Bhasin et al. 2020)
- Liver damage and dysfunction (Kicman 2008)
- Acne and oily skin
- Hair loss
- Mood swings and aggression
- Gynecomastia (enlargement of breast tissue in males)
- Testicular atrophy (shrinkage of the testicles)
- Infertility
These side effects can have serious consequences on an athlete’s health and well-being. For example, heart disease and stroke are leading causes of death among athletes, and the use of methyltestosterone can increase the risk of these conditions (Bhasin et al. 2020). Liver damage can also be life-threatening and may require a liver transplant in severe cases (Kicman 2008).
In addition to physical side effects, the use of methyltestosterone can also have psychological effects on athletes. The hormone can alter mood and behavior, leading to increased aggression and irritability. This can not only affect an athlete’s performance but also their relationships with others.
Detection of Methyltestosterone in Athletes
Methyltestosterone is a banned substance in sports and is included on the World Anti-Doping Agency’s (WADA) Prohibited List. It is classified as an anabolic agent and is prohibited at all times, both in and out of competition. Athletes who test positive for methyltestosterone can face serious consequences, including disqualification, suspension, and loss of medals or titles.
The detection of methyltestosterone in athletes is primarily done through urine testing. The metabolites of methyltestosterone can be detected in urine for up to 3-4 days after use. However, the detection window may be longer for injectable forms of the hormone, as they have a longer half-life in the body.
Alternatives to Methyltestosterone
While methyltestosterone may provide short-term benefits for athletes, the potential side effects and risks associated with its use make it a dangerous choice. Fortunately, there are alternative options available for athletes looking to enhance their performance and muscle growth.
One such alternative is testosterone replacement therapy (TRT), which is a medically supervised treatment for individuals with low testosterone levels. TRT involves the use of testosterone in a controlled and monitored manner, which can provide similar benefits to methyltestosterone without the associated risks and side effects.
Another alternative is the use of selective androgen receptor modulators (SARMs), which are compounds that selectively target androgen receptors in the body. SARMs have been shown to have similar anabolic effects to testosterone, but with fewer androgenic side effects (Thevis et al. 2019). However, their use in sports is also prohibited by WADA.
Expert Comments
The use of methyltestosterone in sports is a concerning issue that needs to be addressed. While it may provide short-term benefits, the potential side effects and risks associated with its use can have long-lasting consequences on an athlete’s health. It is important for athletes to understand the dangers of using this hormone and to explore safer alternatives for enhancing their performance.
