Proviron (active ingredient: Mesterolone) is a powerful oral androgen used in sports pharmacology for its anti-estrogenic effects, libido enhancement, and ability to increase muscle hardness. It is a DHT-derived compound that does not aromatize, making it a popular addition to steroid cycles and post-cycle therapy (PCT).
Unlike aromatase inhibitors (AIs), Proviron does not reduce estrogen production but prevents its activity at the receptor level, while simultaneously improving the androgen-to-estrogen ratio. It also helps reduce SHBG (sex hormone-binding globulin), making more free testosterone available in the body.
Main Benefits:
- Improves libido and sexual performance
- Enhances muscle density and dryness
- Reduces estrogenic effects without harsh suppression
- Lowers SHBG – increases free testosterone
- Supports mood, energy, and motivation during a cycle
Typical Uses:
- As part of on-cycle estrogen control (alongside or instead of AIs)
- To boost libido and androgenic tone on TRT or low-testosterone cycles
- In PCT to support hormonal balance and sexual health
Recommended Dosage:
- Standard use: 25–50 mg daily
- Advanced cycles: Up to 75 mg/day (short term)
- Cycle length: 4–8 weeks
