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.


Key Benefits of Mass 450

✅ Extreme Muscle Growth

The 3-in-1 steroid combination enhances hypertrophy, muscle fiber repair, and lean mass gains.

✅ Explosive Strength & Power

Experience rapid strength increases and train at higher intensities.

✅ Improved Recovery & Endurance

Enhanced red blood cell production leads to faster recovery times and better oxygen delivery to muscles.

✅ Fewer Injections

With 450mg per mL, you get powerful results with fewer weekly injections—convenient and effective.

✅ Trusted Quality

Manufactured by Onyx Pharma, a respected European lab known for pharmaceutical-grade, lab-tested compounds.


Recommended Dosage

  • Beginner: 300–450mg/week (0.7–1mL total, split into two injections)

  • Intermediate/Advanced: 600–900mg/week (1.3–2mL, split into 2–3 injections)

  • Cycle Duration: 8–12 weeks

To maintain consistent blood levels, inject twice weekly (e.g., Monday & Thursday).

⚠️ Always follow with a Post Cycle Therapy (PCT) to support natural testosterone recovery and maintain your gains. See our blog for full PCT guidance.


Is Mass 450 Right for You?

Mass 450 is ideal if you’re:

  • Focused on serious bulking

  • Looking to combine three compounds in one vial

  • Wanting to simplify your injection routine

  • Experienced in anabolic steroid use and looking to take it up a level

This product is not recommended for beginners or users unaccustomed to powerful blends.


Final Thoughts

Mass 450 offers elite-level performance enhancement for those who demand maximum gains with minimal hassle. Its high dose per mL, combination of synergistic compounds, and reputation for delivering real results make it one of the most effective bulking solutions on the market.

Whether you’re aiming to break a plateau, build mass faster, or transform your physique, Mass 450 is your go-to solution.
