Masteroxyl 100 mg

Masteroxyl 100 – Drostanolone Propionate by Kalpa Pharmaceuticals

Masteroxyl 100 is a potent injectable anabolic steroid from Kalpa Pharmaceuticals, featuring Drostanolone Propionate at a dosage of 100 mg/mL. Known by its trade name Masteron, this fast-acting DHT-derived compound is favored by bodybuilders during cutting cycles and contest prep for its unparalleled muscle hardening, anti-estrogenic activity, and ability to enhance physique definition.

What is Drostanolone Propionate Used For?

Drostanolone Propionate is widely used to improve muscle density, reduce subcutaneous water retention, and enhance vascularity. Because it doesn't convert to estrogen, it's especially useful for athletes seeking a lean, dry look. According to clinical references from the NIH, DHT derivatives like drostanolone help preserve lean tissue during hypocaloric states without inducing estrogenic side effects.

Key Benefits of Masteroxyl 100

• Dry, hard muscle gains without water retention
• Enhanced vascularity and physique definition
• Anti-estrogenic effects—ideal for contest prep
• Minimal risk of gynecomastia
• Preserves lean mass while cutting

How to Use Masteroxyl 100

Due to its short half-life (~2 days), Masteroxyl 100 is commonly injected every other day (EOD) or 3–4 times weekly. Recommended cycle length is 6–10 weeks. Dosage typically ranges from 300–500 mg per week for intermediate users, with advanced users sometimes going up to 600 mg/week.

To maximize results, Masteroxyl 100 is often stacked with:

• Testoxyl Propionate 100 – ideal for short ester cutting cycles
• Turanaxyl 10 – dry oral steroid for added strength and definition
• Clomixyl 50 – for recovery after the cycle
• Boldaxyl 300 – for lean bulking/recomp phases
• Arimixyl – optional estrogen control, especially in stacks with aromatizing compounds

Post-Cycle Therapy (PCT)

Even though Masteroxyl 100 has low suppression compared to some other anabolic steroids, it still inhibits natural testosterone production. Begin PCT approximately 4–5 days after your last injection, using Nolvaxyl 20 or Clomixyl 50 for 4–6 weeks.

Side Effects of Drostanolone Propionate

• No estrogenic side effects (no aromatization)
• Possible hair thinning in genetically predisposed individuals
• Mild suppression of natural testosterone
• Androgenic side effects (e.g., acne, oily skin)

Drostanolone Propionate is not liver toxic and is well tolerated in most healthy male users.
