Masteroxyl 200, containing Drostanolone Enanthate, is an injectable anabolic-androgenic steroid (AAS) at 200 mg/ml in a 10 ml vial from Kalpa Pharmaceuticals. Known as Masteron, it's used in bodybuilding for muscle definition and hardness during cutting cycles, acting as a mild androgen with anti-estrogenic properties. It has low hepatotoxicity and does not aromatize, minimizing estrogenic effects with a longer half-life than its propionate counterpart.
Masteroxyl 200 enhances muscle hardness and density by inhibiting aromatase activity, preventing water retention and promoting a lean physique. It supports strength and lean muscle retention during calorie deficits, offering sustained effects due to the enanthate ester. Users notice improved muscle definition and a drier look within weeks, with effects lasting throughout the cycle.
Masteroxyl 200 can be safe when used responsibly under professional guidance, but it carries risks due to its androgenic nature and potential testosterone suppression. Side effects may include acne, hair loss, and cardiovascular strain. Regular bloodwork to monitor lipids, liver function, and hormonal levels is essential. Not recommended for beginners, women (due to virilization risk), or those with cardiovascular or prostate issues without medical oversight.
Common side effects of Masteroxyl 200 include androgenic effects (acne, hair loss, aggression), cardiovascular strain (high BP, altered lipids), and testosterone suppression. Less common issues include oily skin or mild injection site reactions. Manage with proper dosing, cardiovascular monitoring, and PCT; consult a professional if severe.
Drostanolone Enanthate has a half-life of approximately 7-10 days, requiring weekly or bi-weekly injections. It remains detectable in the body for up to 2-3 months, depending on dosage, metabolism, and testing methods. Bloodwork and professional guidance are advised for precise clearance timelines.
Drostanolone Enanthate binds to androgen receptors (AR), promoting muscle hardness and density while inhibiting aromatase to reduce estrogen levels. Its anti-estrogenic properties prevent water retention, enhancing a lean, defined look. The longer enanthate ester ensures sustained release and prolonged effects. Users notice muscle definition within 1-2 weeks. What doesn't happen: no significant mass gain or liver toxicity, but androgenic control is critical.
Masteroxyl 200 excels for bodybuilders in cutting cycles, requiring a calorie-deficit diet and strength training to maximize its aesthetic and anti-estrogenic effects with fewer injections.
Best for intermediate to advanced bodybuilders seeking muscle definition in cutting cycles; suitable for men. Not recommended for beginners, women (due to virilization risk), or those with cardiovascular or prostate issues.

Review labs with a professional where lawful to ensure authenticity and safe dosing.
Start PCT 7-10 days after last injection due to longer half-life; use tamoxifen (20-40 mg/day) or clomiphene (50-100 mg/day) for 4-6 weeks, possibly with HCG (500-1000 IU/week) for severe suppression. Bloodwork guides HPTA recovery, ensuring sustained gains and hormonal balance.
