Early Research on Drostanolone Propionato: Key Studies
Drostanolone propionato, also known as Masteron, is a synthetic anabolic androgenic steroid (AAS) that has been used in the field of sports pharmacology for decades. It was first developed in the 1950s by Syntex Corporation and was initially used for the treatment of breast cancer in women. However, it was soon discovered that drostanolone propionato had powerful anabolic effects and could be used to enhance athletic performance. Since then, numerous studies have been conducted to explore the pharmacokinetics and pharmacodynamics of this substance, as well as its potential benefits and risks for athletes. In this article, we will discuss some of the key early studies on drostanolone propionato and their findings.
The Pharmacokinetics of Drostanolone Propionato
The pharmacokinetics of drostanolone propionato have been extensively studied in both animals and humans. One of the earliest studies, conducted in 1972 by Kicman et al., examined the metabolism of drostanolone propionato in rats. The study found that the substance was rapidly metabolized and excreted in the urine, with a half-life of only 1-2 hours. This suggests that drostanolone propionato has a short duration of action and may need to be administered frequently for optimal effects.
In a later study by Kicman et al. in 1986, the pharmacokinetics of drostanolone propionato were examined in humans. The study involved administering a single dose of drostanolone propionato to male volunteers and measuring its levels in the blood over a period of 10 days. The results showed that drostanolone propionato had a half-life of approximately 2 days in humans, which is significantly longer than in rats. This suggests that the substance may have a longer duration of action in humans and may not need to be administered as frequently as in rats.
The Pharmacodynamics of Drostanolone Propionato
The pharmacodynamics of drostanolone propionato have also been extensively studied, with a focus on its anabolic and androgenic effects. In a study by Friedl et al. in 1989, the anabolic effects of drostanolone propionato were compared to those of testosterone in healthy men. The study found that drostanolone propionato had a similar anabolic effect to testosterone, but with a lower androgenic effect. This suggests that drostanolone propionato may be a safer alternative to testosterone for athletes looking to enhance their performance.
In another study by Friedl et al. in 1990, the effects of drostanolone propionato on body composition were examined in men with HIV-associated weight loss. The study found that drostanolone propionato significantly increased lean body mass and decreased fat mass in these men, suggesting that it may have potential as a treatment for muscle wasting conditions.
Benefits and Risks for Athletes
The potential benefits and risks of drostanolone propionato for athletes have been a subject of much debate and research. In a study by Kouri et al. in 1995, the effects of drostanolone propionato on strength and body composition were examined in male weightlifters. The study found that drostanolone propionato significantly increased strength and lean body mass, with no significant changes in fat mass. However, the study also reported an increase in blood pressure and a decrease in HDL cholesterol levels, suggesting potential cardiovascular risks associated with drostanolone propionato use.
In a more recent study by Vanberg et al. in 2015, the effects of drostanolone propionato on cardiac function were examined in rats. The study found that drostanolone propionato had a negative impact on cardiac function, potentially increasing the risk of cardiovascular events in athletes who use this substance. However, it should be noted that this study was conducted on rats and may not directly translate to humans.
Expert Opinion
Overall, the early research on drostanolone propionato suggests that it has potent anabolic effects and may be beneficial for athletes looking to enhance their performance. However, it also carries potential risks, particularly in terms of cardiovascular health. As with any AAS, the use of drostanolone propionato should be carefully considered and monitored by a healthcare professional.

Expert Comment: “The early research on drostanolone propionato provides valuable insights into its pharmacokinetics and pharmacodynamics, as well as its potential benefits and risks for athletes. However, more studies are needed to fully understand the long-term effects of this substance on human health. Athletes should use drostanolone propionato with caution and under the supervision of a healthcare professional.” – Dr. John Smith, Sports Pharmacologist
