What Makes Masteron Unique?

Masteron Propionate does not aromatize to estrogen, which helps reduce bloating and supports a dry, aesthetic physique. It's also mildly anti-estrogenic, often used alongside aromatizing compounds like testosterone to mitigate side effects. With an active life of just 2–3 days, this short-acting ester is ideal for advanced users seeking precise control over results and side effects.

Dosing Protocol

The standard dosage ranges from 100 to 150 mg every other day (EOD). Some competitive athletes may increase the dose to 400–600 mg per week, depending on individual goals and stacking strategy.

Stacking Recommendations

Stealth Labs Masteron Propionate works well in cutting stacks and pre-contest protocols. Consider stacking with:

• Stealth Trenbolone Acetate – for extreme muscle definition and strength
• Stealth Testosterone Propionate – synergistic hormonal base for short cycles
• Stealth Winstrol 50 mg – enhances muscle hardness and fat loss synergy
• Halotestin 10 – for last-week contest aggression and vascularity

Estrogen & Androgenic Effects

Masteron does not convert to estrogen, meaning estrogen-related side effects such as gynecomastia and water retention are virtually eliminated. Androgenic side effects are mild but may include oily skin or increased libido. It is not recommended for women due to high virilization risk.

PCT & Recovery

Because it is suppressive to natural testosterone production, proper post-cycle therapy is important. Begin PCT 4–5 days after the final injection using Nolvadex or Clomid for 4 weeks. Many users also include HCG mid-cycle to prevent testicular atrophy and aid faster recovery.

Scientific Background

Drostanolone was originally developed to treat breast cancer in women. Its anti-estrogenic and anabolic effects have since made it popular in the athletic community. For clinical data, see this review on DHT-based anabolic steroids.
