The Effects of Drostanolone Propionate on Muscle Strength Increase
Drostanolone propionate, also known as Masteron, is a synthetic anabolic androgenic steroid (AAS) that has gained popularity among bodybuilders and athletes for its ability to increase muscle strength and improve physical performance. This article will explore the pharmacokinetics and pharmacodynamics of drostanolone propionate and its effects on muscle strength, as well as provide real-world examples and cite peer-reviewed articles to support its use in sports pharmacology.
Pharmacokinetics of Drostanolone Propionate
Drostanolone propionate is a modified form of dihydrotestosterone (DHT), with an added methyl group at the carbon 2 position. This modification allows drostanolone propionate to resist metabolism by the enzyme 3-hydroxysteroid dehydrogenase, resulting in a longer half-life compared to DHT (Vida, 1969). The half-life of drostanolone propionate is approximately 2-3 days, making it a fast-acting steroid (Kicman, 2008).
After administration, drostanolone propionate is rapidly absorbed into the bloodstream and reaches peak plasma levels within 1-2 days (Kicman, 2008). It is then metabolized in the liver and excreted in the urine as conjugated metabolites (Vida, 1969). The elimination half-life of drostanolone propionate is approximately 8-10 days, with a detection time of up to 3 weeks (Kicman, 2008).
Pharmacodynamics of Drostanolone Propionate
Drostanolone propionate exerts its effects by binding to androgen receptors in muscle tissue, promoting protein synthesis and increasing nitrogen retention (Kicman, 2008). This results in an increase in muscle mass and strength, as well as improved recovery time between workouts (Kicman, 2008).
Additionally, drostanolone propionate has a high affinity for the aromatase enzyme, which converts testosterone into estrogen. By inhibiting aromatase, drostanolone propionate can prevent the conversion of testosterone into estrogen, reducing the risk of estrogen-related side effects such as gynecomastia (Kicman, 2008).
Effects on Muscle Strength
The use of drostanolone propionate has been shown to significantly increase muscle strength in both trained and untrained individuals. In a study by Kouri et al. (1995), 10 healthy men were given 100mg of drostanolone propionate every other day for 10 weeks. The results showed a significant increase in muscle strength, with an average increase of 10-15% in bench press and squat strength.
In another study by Kouri et al. (1999), 20 healthy men were given 100mg of drostanolone propionate every other day for 6 weeks. The results showed a significant increase in muscle strength, with an average increase of 20-25% in bench press and squat strength.
Furthermore, a study by Hartgens et al. (2001) compared the effects of drostanolone propionate and testosterone enanthate on muscle strength in 21 healthy men. The results showed that both steroids significantly increased muscle strength, with drostanolone propionate resulting in a greater increase in bench press strength compared to testosterone enanthate.
Real-World Examples
Drostanolone propionate has been used by many professional athletes and bodybuilders to improve their physical performance and increase muscle strength. One notable example is the former Olympic sprinter Ben Johnson, who tested positive for drostanolone propionate at the 1988 Summer Olympics (Yesalis et al., 1993). Johnson’s use of drostanolone propionate was believed to have contributed to his record-breaking performance in the 100-meter dash.
In the bodybuilding world, drostanolone propionate is commonly used during the cutting phase to help athletes achieve a lean and defined physique. It is also used by powerlifters and strength athletes to improve their performance and increase muscle strength.
Expert Opinion
According to Dr. Charles E. Yesalis, a leading expert in sports pharmacology, drostanolone propionate is a potent steroid that can significantly increase muscle strength and improve physical performance (Yesalis et al., 1993). However, he also notes that its use comes with potential side effects and should only be used under medical supervision.
Dr. Yesalis also emphasizes the importance of using drostanolone propionate in combination with proper training and nutrition to achieve optimal results. He cautions against the use of high doses or prolonged use, as it can lead to adverse effects on the liver and cardiovascular system (Yesalis et al., 1993).

Expert Comments
“Drostanolone propionate is a powerful steroid that can significantly increase muscle strength and improve physical performance. However, it should only be used under medical supervision and in combination with proper training and nutrition to achieve optimal results. Its use comes with potential side effects and should not be taken lightly.” – Dr. Charles E. Yesalis
