Mesterolone
Proviron by Dragon Pharma contains Mesterolone, a DHT-derived oral anabolic steroid known for its ability to enhance androgenic activity, improve libido, and control estrogenic side effects. Each pack includes 100 tablets at 25 mg, making it a versatile addition to bodybuilding cycles for a hard, chiseled physique. With a half-life of approximately 12–13 hours, Proviron delivers consistent effects with daily dosing.
What It Is
Mesterolone, marketed as Proviron, is a synthetic androgen with mild anabolic properties. Originally developed for medical use in treating hypogonadism and male infertility, it's widely used in bodybuilding to enhance androgen levels, boost libido, and counteract estrogenic side effects from aromatizing steroids like testosterone. Its oral bioavailability and non-aromatizing nature make it a unique tool for physique enhancement.
How It Works
Proviron binds strongly to androgen receptors, amplifying androgenic effects like muscle hardness and libido without converting to estrogen or DHT. It also binds to sex hormone-binding globulin (SHBG), increasing free testosterone levels for enhanced anabolic activity. Its mild anti-estrogenic properties help reduce gynecomastia and water retention when used with aromatizing steroids. The half-life of 12–13 hours requires daily dosing, with detection times up to 5–6 weeks for drug-tested athletes.
Benefits
- Muscle Hardness: Enhances definition for a chiseled, vascular look.
- Libido Boost: Improves sexual drive and performance.
- Estrogen Control: Reduces gynecomastia and water retention risks.
- Increased Free Testosterone: Binds SHBG to amplify testosterone effects.
- Mild Anabolic Effects: Supports lean muscle maintenance in cutting cycles.
Who It's For
Proviron is ideal for male bodybuilders aged 21–40 using aromatizing steroids (e.g., testosterone, Dianabol) in bulking or cutting cycles, seeking muscle definition, libido support, and estrogen control. It's suitable for intermediate to advanced users. Not for: Women (due to virilization risks), individuals under 21, or those with prostate or liver issues. Medical supervision and blood work are essential.
How to Use
Dosage: Typical dosage for men is 25–75 mg/day (1–3 tablets), split into 1–2 doses. Beginners should start at 25 mg/day to assess tolerance. Women, if using, should not exceed 25 mg/day under strict medical supervision due to virilization risks.
Administration: Take orally with water, with or without food. Administer consistently at the same times daily for stable blood levels. Use throughout steroid cycles for estrogen control or as needed for libido support. Cycles typically last 6–12 weeks, aligned with the main cycle.
Results Timeline: Muscle hardness, libido improvement, and estrogen control are noticeable within 1–2 weeks, with peak effects by 4–6 weeks when paired with a proper cycle and diet.
Stacking Suggestions
Proviron is typically used as a supportive compound:
- Cutting Stack: Combine with Testosterone Propionate (100–200 mg/week) and Winstrol (25–50 mg/day) for enhanced definition.
- Bulking Stack: Pair with Testosterone Enanthate (250–500 mg/week) to manage estrogen and boost free testosterone.
- Support: Use with Nolvadex (10–20 mg/day) for additional estrogen control if needed.
Side Effects
Proviron is well-tolerated but may cause:
- Androgenic: Acne, hair loss (in predisposed individuals), or increased body hair.
- Hormonal: Minimal testosterone suppression; PCT may be needed if used long-term.
- Other: Rare headaches or mood changes at higher doses.
- Hepatotoxicity: Low risk, but monitor liver function with prolonged use.
Proviron has no estrogenic side effects. Regular blood work to monitor testosterone and liver function is recommended.
Post Cycle Therapy (PCT)
Proviron causes minimal testosterone suppression, but PCT is recommended if used with suppressive steroids. Use Clomid (25–50 mg/day) and Nolvadex (20 mg/day) for 4 weeks, starting based on the main steroid's half-life. Proviron is not typically used in PCT due to its androgenic activity. Monitor testosterone levels via blood work.
