Proviron (Mesterolone)

What it does:

Proviron (Mesterolone) is a unique oral androgenic steroid known for its ability to enhance muscle hardness, libido, and hormonal balance. It does not aromatize and acts as an anti-estrogen by binding to aromatase, which can help reduce estrogenic side effects from other compounds. It also increases the free testosterone ratio in the body by binding to SHBG (sex hormone-binding globulin).

Normal Applications:

Medically used to treat low testosterone, impotence, and male infertility, Proviron has become a popular support compound in bodybuilding. It is often included in cycles to increase androgenic tone, enhance libido, and help counter estrogen-related side effects.

Common Side Effects:

Proviron has minimal estrogenic activity but may still cause androgenic side effects like acne, hair thinning, and increased facial/body hair. It is not liver toxic and has a relatively low risk of cardiovascular strain compared to other orals. Long-term use may suppress natural testosterone.

Administration Recommendations & Ideal Dosages:

Typical dosages range from 25–75 mg daily, depending on user needs. It is often run throughout a cycle or even during PCT to maintain libido and mental sharpness. It stacks well with testosterone, Anavar, or Winstrol. Women rarely use Proviron due to its androgenic profile.
