Mestenon 25

Overview of Mesterolone

Mesterolone, commonly known as Proviron, is a highly sought‑after compound in sports. It is valued for its ability to increase androgen levels, which supports the development of lean muscle mass and improved athletic performance. Athletes frequently include Mesterolone in their regimens to optimize testosterone balance and reach their performance goals.

Pharmacological Classification

• Anabolic‑Androgenic Steroid: Mesterolone is classified as an anabolic‑androgenic steroid, which is important for its role in enhancing androgen levels.

Mechanism of Action

• Androgen Receptor Binding: Mesterolone is a synthetic androgen and anabolic steroid that binds to the androgen receptor (AR), the biological target of androgens such as testosterone and dihydrotestosterone (DHT).
• Properties: It possesses modest androgenic and anabolic properties, making it suitable for masculinization. Mesterolone has no estrogenic properties, and its androgenic and anabolic potencies are relatively low due to its lack of potentiation by 5‑reductase in “androgenic” tissues and inactivation by 3‑HSD in skeletal muscle. However, it still maintains a higher ratio of anabolic to androgenic action compared to testosterone.

Therapeutic Benefits

• Lean Muscle Development: Mesterolone is used to support the development of lean muscle mass and enhance athletic performance by increasing androgen levels.

Potential Side Effects

Users of Mesterolone may experience:

• Common Side Effects: Itching, fever, rash, weight gain, hives, abdominal pain, hot flashes, indigestion, nausea, and vomiting.

Recommended Dosage

• Initial Dosage: For adult males, a dosage of 25‑50 mg three times a day is typically used in the initial stages.
• Maintenance Dosage: A dosage of 25 mg two to three times a day is recommended for maintenance.
• Female Use: This male hormone is not recommended for females.

Mesterolone is an effective option for athletes looking to enhance their androgen levels and improve performance. Monitoring for potential side effects and consulting healthcare professionals for personalized guidance is essential.
