Monster Mass Injectable – 50 mg/mL Oxymetholone + 25 mg/mL Methandrostenolone – 10 mL Vial

The Ultimate Bulking Stack in One Vial

Overview

Monster Mass combines two of the most legendary anabolics — Oxymetholone (Anadrol) and Methandrostenolone (Dianabol) — into one powerful injectable formula. Both compounds are traditionally used in oral form but are highly hepatotoxic due to their C17-alpha alkylated structures. By formulating them as injectables, Monster Mass delivers their extreme anabolic effects while bypassing first-pass liver metabolism, reducing hepatotoxic stress and improving bioavailability.

This combination is designed for advanced users seeking maximum size, strength, and performance in the shortest timeframe possible.

Key Benefits

• Reduced Liver Stress – Injectable delivery avoids much of the hepatotoxicity associated with oral Anadrol and Dianabol.

• Unmatched Mass & Strength Gains – Synergistic effect of two of the strongest bulking agents ever developed.

• Rapid Size Increase – Promotes glycogen storage and muscle cell volumization for dramatic fullness and power.

• Improved Bioavailability – Direct bloodstream delivery provides consistent blood levels and efficiency.

• Stacked in a Single Vial – Convenience of combining Anadrol + Dianabol in one injectable solution.

Typical Dosing Protocols

• Common Range: 1 mL per day = 50 mg Oxymetholone + 25 mg Methandrostenolone.

• Cycle Duration: Generally 3–5 weeks, due to the potency and high anabolic load.

• Stacking Use: Typically run with a testosterone base or other long-ester injectables in advanced bulking cycles.
