MASTEROXYL 100 MG Detailed

Kalpa Pharmaceuticals Masteroxyl 100 – Drostanolone Propionate

What is Masteroxyl 100?

Masteroxyl 100 is an injectable anabolic steroid containing Drostanolone Propionate (100 mg/mL), a DHT-derived compound known for its potent anti-estrogenic and hardening effects. Produced by Kalpa Pharmaceuticals, it's commonly used during cutting phases for lean gains, strength, and enhanced muscle definition.

Benefits of Masteroxyl 100

Promotes dry, lean muscle gains
Zero estrogenic conversion – no water retention or gynecomastia
Improves muscle density and definition
May exhibit anti-estrogenic properties when stacked

Recommended Cycle & Dosage

Typical dosage ranges from 300–700 mg per week, split into injections every other day. Masteroxyl 100 is often stacked with Testoxyl Propionate or Trenboxyl Acetate for advanced cutting stacks. For best results, cycle duration is generally 6–8 weeks.

Stacking Advice

Many athletes combine Masteroxyl with compounds that aromatize to offset estrogenic effects. However, Masteroxyl itself has no conversion to estrogen, similar in behavior to Proviroxyl. This makes it ideal for hardening without added bloat.

Post-Cycle Therapy (PCT)

As with all suppressive AAS, include a proper PCT using Clomixyl or Nolvaxyl to restore natural testosterone function and maintain gains.
