Drostanol Enanthate, manufactured by SP-Laboratories, is a widely recognized injectable drug that has gained popularity for its unique properties and applications. This article aims to provide a comprehensive overview of Drostanol Enanthate, including its general description, indications, contraindications, uses in bodybuilding and sports, medical action, combination with other drugs, dosage guidelines, and potential side effects.

General Description:

Drostanol Enanthate is a synthetic anabolic-androgenic steroid derived from dihydrotestosterone (DHT). It is commonly known by its trade name Masteron, and it falls under the category of long-acting esterified steroids due to the enanthate ester attached to the parent compound. This modification prolongs the release of the active substance into the bloodstream, allowing for less frequent injections compared to its propionate counterpart.


Drostanol Enanthate is not approved for medical use by regulatory agencies and is primarily used off-label. It was initially developed to treat breast cancer due to its anti-estrogenic properties. However, its medical use has diminished over time due to the availability of more effective treatments.


Individuals with a history of hypersensitivity or allergic reactions to Drostanol Enanthate or any of its components should avoid using this drug. Additionally, individuals with existing medical conditions such as prostate cancer, liver dysfunction, cardiovascular issues, and kidney problems should refrain from using Drostanol Enanthate.

Uses in Bodybuilding and Sports:

Drostanol Enanthate has gained considerable popularity in the bodybuilding and sports communities due to its ability to enhance muscle definition and hardness. Athletes use it during cutting phases to achieve a lean and chiseled appearance, as it helps reduce water retention and fat accumulation. Its anti-estrogenic properties can aid in preventing estrogen-related side effects, such as gynecomastia.

Medical Action:

Drostanol Enanthate functions as an androgen receptor agonist, binding to and activating the androgen receptors in the body. This results in increased nitrogen retention, protein synthesis, and red blood cell production, contributing to muscle growth, strength enhancement, and improved overall performance.

Combination with Other Drugs:

In bodybuilding and sports, Drostanol Enanthate is often combined with other compounds to maximize results. It is commonly stacked with testosterone-based compounds and other cutting steroids like Winstrol or Anavar. These combinations are designed to enhance the effects of each component and provide a synergistic approach to achieving desired outcomes.

Achieving desired bodybuilding and athletic goals often involves using a combination of different compounds to enhance effects and mitigate potential side effects. Drostanol Enanthate is no exception, as it is frequently stacked with other steroids to create a synergistic effect.

  1. Testosterone: Combining Drostanol Enanthate with testosterone-based compounds can help maintain healthy testosterone levels while optimizing muscle growth and performance. The addition of testosterone counteracts potential adverse effects on mood and libido that can occur with the use of anabolic steroids.
  2. Winstrol: Stacking Drostanol Enanthate with Winstrol (Stanozolol) can amplify the benefits of both drugs during cutting cycles. Winstrol’s ability to enhance muscle hardness and vascularity complements Drostanol Enanthate’s effects on muscle definition, creating a more pronounced and aesthetic physique.
  3. Anavar: Another popular choice for combination is Drostanol Enanthate with Anavar (Oxandrolone). This pairing is particularly well-suited for female athletes due to Anavar’s relatively mild androgenic effects, along with Drostanol Enanthate’s potential for lean muscle preservation and definition.
  4. Trenbolone: For advanced users seeking significant muscle gains and enhanced conditioning, a combination of Drostanol Enanthate and Trenbolone can be considered. However, due to the potency and potential side effects of Trenbolone, this combination should be approached with caution and thorough understanding.

Dosage Guidelines:

Dosages of Drostanol Enanthate can vary based on individual goals and experience levels. For male athletes and bodybuilders, a typical dosage ranges from 300 to 600 milligrams per week, administered through intramuscular injections. Female users should exercise caution due to the risk of virilization and generally aim for lower doses.

Side Effects:

While Drostanol Enanthate is generally well-tolerated when used responsibly, it is not without potential side effects. Common adverse reactions include androgenic effects such as oily skin, acne, and increased facial/body hair growth. Virilization symptoms in women can include deepening of the voice and clitoral enlargement. Other potential side effects include cardiovascular strain, liver stress, and suppression of natural testosterone production.


Drostanol Enanthate, developed by SP-Laboratories, remains a prominent injectable drug in the realm of bodybuilding and sports. Its unique properties and benefits, such as enhanced muscle definition and hardness, make it a sought-after choice for athletes aiming to achieve their desired physique. However, it’s crucial to approach the use of Drostanol Enanthate with caution, considering both its potential benefits and associated risks. Consulting with a medical professional before use is essential to ensure safety and informed decision-making.
