Mesterolone Acetate Watson Proviron: Comprehensive Guide USA

What is Mesterolone Acetate Watson ?

Proviron (Mesterolone Acetate Watson) is a powerful anti-estrogen. Derived from DHT (Dihydrotestosterone), Proviron does not possess anabolic properties, making it an effective anti-aromatic. It prevents androgens from converting into estrogen, making it a crucial part of a steroid regimen. Combining Proviron with Nolvadex creates a formidable tandem for support and protection during your cycle.

Clinical Studies on Mesterolone Acetate Watson (Proviron)

Proviron Clinical Studies: Proviron is medically used to address issues related to a lack of the male sex hormone (androgen), Testosterone. In the 1970s, Proviron showed some success in controlled studies of men with various forms of depression. In a more recent clinical trial, 38 men with dysthymia received doses of 75 mg daily for four weeks, showing significant improvement in symptoms like anxiety, lack of desire, and lack of confidence. Dysthymia is a mood disorder involving chronic depression.

A second part of this study administered higher doses (450 mg/day) to 52 individuals with dysthymia, aged around 40 years. This six-week trial found no significant differences between the Proviron and placebo groups, likely due to the high doses administered. However, there was a noted decrease in luteinizing hormone (LH) levels, which stimulates testosterone production.

Positive Effects of Mesterolone Acetate Watson (Proviron)

Positive Effects of Proviron: Interestingly, Proviron is legally considered an anabolic steroid in some countries. Despite this classification, it does not have significant direct anabolic effects. However, Proviron can produce several benefits for steroid users:

  • Prevention of Libido Loss: Proviron is potent in preventing loss of libido during a steroid cycle. As a powerful androgen, it significantly impacts libido, making it almost as effective as a small dose of Viagra according to some users.
  • Reduction in Estrogen Levels: During steroid treatment, Testosterone and other androgens can convert to estrogen via the aromatase enzyme. Proviron has a stronger affinity for the aromatase enzyme than Testosterone, reducing estrogen conversion and allowing androgens to circulate freely, enhancing anabolic effects.
  • Muscle Growth: Proviron binds to androgen receptors in muscle tissue, facilitating muscle growth.
  • Fat Burning Potential: Proviron’s androgenic properties may induce adipose tissue to release fatty acids, aiding in fat loss.

Proviron Side Effects Mesterolone Acetate Watson (Proviron)

Normal doses of Proviron rarely cause negative effects. However, if dosages are not adhered to, slight water retention may occur. Using Nolvadex alongside Proviron can mitigate this. Recommended dosages are:

  • 25 mg daily for men and women for normal treatment
  • 50 mg daily for men on heavy steroid regimens

Women should use Proviron cautiously due to its androgenic nature, which can cause virilization (development of male characteristics).

How to Use Mesterolone Acetate Watson Proviron

Proviron Dosage: The typical dose of Proviron ranges from 25 mg to 250 mg. For effective results, the recommended dose is 50 mg daily. Although well-tolerated, high doses and long-term use can cause negative side effects, especially virilization in women.

Proviron Cycle: The ideal Proviron cycle is 10 to 12 weeks. Using Proviron can suppress natural testosterone production, so a longer cycle is needed. Proviron is often combined with Testosterone due to its binding properties, enhancing androgenic effects.

Benefits of Mesterolone Acetate Watson Proviron

Advantages of Proviron

Proviron is particularly beneficial for individuals with hypogonadism (low testosterone production). Key benefits include:

  • Increased muscle mass
  • Increased bone density
  • Fat loss
  • Great for cutting cycles
  • Treatment for infertility and impotence
  • Inhibits aromatization
  • No injection required
  • Adds lean muscle mass

Mesterolone Acetate Watson Proviron in Post Cycle Therapy (PCT) 

While once popular in PCT to alleviate estrogen effects, modern alternatives like Clomiphene, Tamoxifen, HCG, and aromatase inhibitors have reduced its use. However, Proviron does not significantly inhibit natural testosterone production and can be used as a fertility enhancer.

Proviron Dosage in a Steroid Cycle

The dosage is typically between 25-50 mg per day, with an active life of 12 hours. Proviron can be detected in the body for up to two months and is not liver toxic, allowing for safe use throughout a 12-14 week cycle.

Combining Proviron: Proviron synergizes well with Winstrol or Trenbolone, aiding definition and reducing water retention, giving the body a hard, defined look.

Proviron as a Bridge Between Cycles: Advanced users can use Proviron as a “bridge” between cycles, maintaining libido and muscle gains with a daily dose of 50 mg during the bridge phase.

Supplementation During a Proviron Cycle: Traditional supplementation remains crucial. Use Omega-3 rich fish oil to control cholesterol levels and a liver protector like Milk Thistle. Higher protein intake is essential for maximizing steroid-induced protein synthesis. A good protein supplement and a pre-workout for better blood flow are recommended.


Proviron (Mesterolone Acetate Watson) offers numerous benefits when used correctly. By following proper dosages and combining it with other supportive supplements, users can achieve significant improvements in muscle mass, libido, and overall performance without many of the common side effects associated with other steroids.
