Why You Should Buy Xeno Labs Omnimass – 500mg/10ml at Steroiduck?
What It Does
Omnimas 500 is a premium mass-building blend containing three powerful compounds at 500mg total per ml:
- Testosterone Enanthate 200mg – The foundation for all cycles, building muscle and strength
- Nandrolone Decanoate 100mg – For joint relief and quality muscle gains
- Boldenone Undecylenate 200mg – For lean mass, endurance, and appetite
This triple-compound formula is specifically designed for serious bulking cycles where maximum size and strength gains are the goal. Each compound works synergistically with the others – Testosterone provides the hormonal base and raw power, Nandrolone adds joint protection and nitrogen retention, while Boldenone increases red blood cells and appetite for eating the massive calories needed to grow.
Within 3-4 weeks once blood levels saturate, you’ll notice dramatic changes – muscles getting fuller, strength climbing weekly, recovery improving dramatically, and your appetite becoming insatiable for eating the food needed to fuel serious growth.
The Main Benefits For You
Maximum Mass-Building Synergy
By combining three proven mass-building compounds, Omnimas 500 creates synergistic muscle growth that exceeds what you’d get from any single compound. The testosterone provides raw anabolic power, nandrolone enhances nitrogen retention and joint health, while boldenone increases endurance and appetite. Together they produce explosive size gains.
Build 25-35 Pounds of Muscle
Over a 16-20 week cycle with proper training and nutrition, you can gain 25-35 pounds of solid muscle mass. This combination is designed for serious off-season bulking when maximum size is the goal. Your frame transforms as you pack on quality mass week after week.
Train Pain-Free
The Nandrolone Decanoate component makes your joints feel amazing. All that knee pain during squats disappears. Your elbows stop aching. You can train heavy without the joint pain that normally limits you. This is crucial for the intense training required to maximize growth.
Insatiable Appetite
The Boldenone component makes you hungry all the time. If you struggle to eat enough calories for serious mass building, this solves the problem. You’ll be ready to eat every 2-3 hours, making it easy to consume the 4000-6000 calories daily needed for maximum growth.
Convenient All-In-One
Instead of buying Testosterone, Deca, and Equipoise separately and drawing from three vials, everything is premixed in perfect ratios. One draw, one injection, all three compounds working together.
Enhanced Endurance
The Boldenone dramatically increases red blood cell production, improving oxygen delivery to muscles. You can train harder, longer, with better endurance. Your work capacity in the gym goes way up.
Only Inject Twice Weekly
All three compounds use long esters. You only need to inject twice weekly (Monday and Thursday) for stable blood levels. Simple, convenient dosing schedule throughout your entire cycle.
FDA DISCLAIMER: This product isn’t intended to diagnose, treat, cure, or prevent any disease. This product contains controlled substances and should only be used under proper medical supervision for legitimate medical purposes.

Recommended Dosage:
500-1000mg per week split into two injections. Beginners start with 500mg weekly (1ml total per week - 0.5ml Monday, 0.5ml Thursday). Intermediate users run 750mg weekly (1.5ml total). Advanced users go to 1000mg weekly (2ml total). This provides:
- At 500mg weekly: 200mg Test E, 100mg Deca, 200mg EQ per week
- At 1000mg weekly: 400mg Test E, 200mg Deca, 400mg EQ per week
Injection Frequency:
Inject twice weekly due to long esters. Monday morning and Thursday evening is most common schedule.
When to Inject:
Inject deep into muscle (glutes, thighs, or shoulders) using 1.5 inch needle. Rotate injection sites each time. The high 500mg concentration may cause more post-injection soreness initially.
Cycle Duration:
16-20 weeks for optimal mass building. The long esters take 4-5 weeks to fully saturate. Shorter cycles waste the compounds. Most serious bulkers run 18-20 weeks for maximum size gains.
Stacking:
This blend already contains everything needed for bulking. Can add oral like Dianabol or Anadrol weeks 1-6 for explosive start. Or add oral like Anavar final 6 weeks if transitioning to cutting phase.
Post Cycle Therapy (PCT):
Absolutely required. All three compounds suppress testosterone completely. Wait 3 weeks after last injection (long esters need to clear), then start aggressive PCT: Nolvadex 40/40/20/20mg daily + Clomid 100/100/50/50mg daily for 4-6 weeks. Consider Cabergoline 0.25mg twice weekly during cycle for prolactin control from Nandrolone.
Most Common:
- Complete testosterone suppression during cycle
- Moderate water retention from testosterone and nandrolone
- Prolactin elevation from Nandrolone (need Cabergoline)
- Acne on back, chest, shoulders
- Gyno risk from testosterone aromatization (need Arimidex)
- Testicular atrophy during cycle
- Significantly elevated red blood cell count from Boldenone
- Possible libido issues if testosterone ratio isn't adequate
Serious Side Effects:
- High hematocrit from Boldenone (blood too thick)
- High blood pressure from water retention
- Negative cholesterol profile
- "Deca dick" - erectile issues from prolactin
- Kidney stress with extended use
- Hair loss if genetically predisposed
How to Manage:
Use Arimidex 0.5mg every other day for estrogen control. Take Cabergoline 0.25mg twice weekly for prolactin management. Donate blood if hematocrit exceeds 54%. Get blood work at weeks 8 and 16. Do cardio 3-4x weekly. Stay hydrated.
