Mass 450 – Triple Blend for Extreme Muscle Gains
What Is Mass 450?
Mass 450 by Onyx Pharma is a high-potency anabolic steroid blend designed for serious bulking cycles. Each 10mL vial contains a powerful mix of three proven compounds:
-
Testosterone Enanthate (150mg)
-
Trenbolone Enanthate (150mg)
-
Nandrolone Decanoate (150mg)
That’s a total of 450mg per mL—making it one of the most concentrated mass-building blends available.
This injectable steroid is favored by bodybuilders and athletes looking to push past natural limits and build size, strength, and performance fast.
How Mass 450 Works
Mass 450 delivers a synergistic combination of long-acting anabolic steroids that work together to create an optimal muscle-building environment:
-
Testosterone Enanthate: Increases muscle protein synthesis and recovery.
-
Trenbolone Enanthate: Boosts muscle density, strength, and fat loss with zero estrogenic side effects.
-
Nandrolone Decanoate: Promotes joint health, lean muscle growth, and overall endurance.
These esters provide a steady release of active hormones into the bloodstream, ensuring stable anabolic levels throughout your cycle for maximum results with fewer injections.
