In the world of bodybuilding and fitness, finding effective supplements that can boost testosterone levels and support muscle growth is crucial. One such supplement that has gained significant attention is 4-Androstenolone. Known for its powerful testosterone boosting properties, 4-Androstenolone has become a popular choice among athletes and fitness enthusiasts. In this article, we will explore the science behind 4-Androstenolone, its benefits, and how it can help you achieve your fitness goals.


4-Androstenolone, also known as 4-DHEA, is a naturally occurring hormone and a precursor to testosterone. Its structure closely resembles regular DHEA, but with a double bond in the 4th position, which has a significant impact on its effects. Unlike regular DHEA, 4-Androstenolone readily converts to 4-androstenediol, a more potent anabolic compound. This increased anabolic potency makes 4-Androstenolone a valuable tool for individuals looking to enhance their muscle growth and strength. (1)

The Science Behind

Numerous studies have explored the effects of 4-Androstenolone on the body. One study published in the Journal of Applied Physiology concluded that testosterone increases muscle mass by enhancing muscle protein synthesis. This finding suggests that by increasing circulating "free" testosterone, individuals can experience noticeable gains in strength, lean tissue growth, and weight gain.

Additionally, 4-Androstenolone has been shown to have a higher conversion rate to testosterone compared to regular DHEA. This means that when taken as a supplement, 4-Androstenolone can potentially provide superior results in terms of muscle building and performance enhancement. (2)

The Benefits of 4-Androstenolone

Increased Testosterone Levels: One of the primary benefits of 4-Androstenolone is its ability to boost testosterone levels in the body. By increasing testosterone, individuals may experience improved muscle growth, enhanced strength, and increased libido.

Lean Muscle Mass: 4-Androstenolone has been shown to aid in the development of lean muscle mass. Its anabolic properties contribute to the growth and repair of muscle tissue, allowing individuals to achieve a more defined and muscular physique.

Enhanced Performance: With increased testosterone levels, individuals may experience improved athletic performance. This can include increased endurance, stamina, and overall energy levels, allowing for more intense and productive workouts.

Reduced Estrogen Conversion: One concern with testosterone boosting supplements is the potential for elevated estrogen levels. However, when using liposomal forms of 4-Androstenolone, the elevation in estrogen appears to be minimal, reducing the risk of unwanted side effects. (4)

How to Use 4-Androstenolone

When it comes to using 4-Androstenolone, it is essential to follow the recommended dosage guidelines. Typically, the suggested serving size is one tablet, and the recommended daily intake should not exceed six tablets. It is crucial to spread out the tablets throughout the day to maintain consistent levels of the supplement in your system.

It is important to note that 4-Androstenolone is classified as a prohormone and should be used as a supplement, not a replacement for proper diet and exercise. While 4-Androstenolone can provide support for testosterone synthesis, it is crucial to incorporate a well-rounded fitness routine and a balanced diet to achieve optimal results. (3)

Potential Side Effects

As with any supplement, it is essential to be aware of potential side effects. While 4-Androstenolone is generally well-tolerated, some individuals may experience mild side effects such as acne, oily skin, or changes in mood. It is always recommended to consult with a healthcare professional before starting any new supplement regimen, especially if you have any pre-existing medical conditions.

The Future of 4-Androstenolone

As research continues to explore the benefits and potential applications of 4-Androstenolone, it is clear that this supplement holds promise in the world of fitness and bodybuilding. With its ability to boost testosterone levels, support muscle growth, and enhance performance, 4-Androstenolone may become an essential tool for individuals looking to optimize their fitness journey.


In conclusion, 4-Androstenolone is a powerful testosterone boosting supplement that can aid in lean muscle mass and enhance athletic performance. With its ability to increase testosterone levels and support muscle growth, 4-Androstenolone has become a popular choice among athletes and fitness enthusiasts. While it is crucial to follow the recommended dosage and consult with a healthcare professional, incorporating 4-Androstenolone into your fitness routine may help you achieve your desired results. Embrace the power of 4-Androstenolone and take your fitness journey to the next level.
