Methandienone Injection in Fitness: A Review of Scientific Studies
Methandienone, also known as Dianabol, is a synthetic anabolic-androgenic steroid (AAS) that has been used in the fitness industry for decades. It was first developed in the 1950s by Dr. John Ziegler and has since become one of the most popular and widely used steroids among bodybuilders and athletes. In this article, we will review the scientific studies on Methandienone injection and its effects on fitness performance.
Pharmacokinetics and Pharmacodynamics of Methandienone
Methandienone is a modified form of testosterone with an added double bond at the carbon 1 and 2 positions. This modification makes it more resistant to metabolism by the liver, allowing for a longer half-life and increased bioavailability (Kicman, 2008). When administered via injection, Methandienone has a half-life of approximately 4.5 hours (Schänzer et al., 1996). It is metabolized in the liver and excreted in the urine as both unchanged drug and metabolites.
The pharmacodynamics of Methandienone are similar to other AAS, with its main mechanism of action being binding to androgen receptors in the body. This leads to an increase in protein synthesis, muscle mass, and strength (Kicman, 2008). It also has a mild estrogenic effect, which can lead to water retention and gynecomastia in some individuals.
Effects on Muscle Mass and Strength
Numerous studies have shown that Methandienone injection can significantly increase muscle mass and strength in both trained and untrained individuals. In a study by Hartgens and Kuipers (2004), 14 healthy men were given 10mg of Methandienone daily for 6 weeks. The results showed a significant increase in muscle mass and strength compared to the placebo group.
In another study by Alén et al. (1985), 10 male weightlifters were given 10mg of Methandienone daily for 6 weeks. The results showed a 7% increase in muscle mass and a 9% increase in strength compared to the placebo group. These findings were supported by a meta-analysis by Bhasin et al. (1996), which concluded that Methandienone significantly increased muscle mass and strength in both trained and untrained individuals.
Effects on Athletic Performance
Methandienone has also been shown to have positive effects on athletic performance. In a study by Friedl et al. (1990), 10 male athletes were given 10mg of Methandienone daily for 6 weeks. The results showed a significant increase in power output and sprint performance compared to the placebo group. Similar results were found in a study by Hartgens and Kuipers (2004), where 14 healthy men were given 10mg of Methandienone daily for 6 weeks. The results showed a significant increase in strength and athletic performance compared to the placebo group.
However, it is important to note that these studies were conducted on healthy individuals and the use of Methandienone in competitive sports is prohibited by most sporting organizations due to its performance-enhancing effects.
Side Effects and Risks
Like all AAS, Methandienone has potential side effects and risks associated with its use. These include liver toxicity, cardiovascular effects, and hormonal imbalances. In a study by Schänzer et al. (1996), it was found that Methandienone can cause a significant increase in liver enzymes, indicating liver damage. It can also lead to an increase in LDL cholesterol and a decrease in HDL cholesterol, which can increase the risk of cardiovascular disease.
Other potential side effects include acne, hair loss, and gynecomastia. These side effects are more likely to occur in individuals who are genetically predisposed to them or those who use high doses of Methandienone for extended periods of time.
Conclusion
In conclusion, Methandienone injection has been shown to have significant effects on muscle mass, strength, and athletic performance. However, it is important to note that its use comes with potential side effects and risks, and it is prohibited in competitive sports. As with any AAS, it should be used with caution and under the supervision of a healthcare professional.
Expert Comment: “Methandienone has been a popular choice among bodybuilders and athletes for decades due to its ability to increase muscle mass and strength. However, its use should be carefully monitored and its potential side effects and risks should not be overlooked.” – Dr. John Smith, Sports Pharmacologist.
