Strengthen Your Defenses with GPX Defense Mode
Support your immune system, optimize sinus comfort, and reclaim your energy with the all-in-one GPX Defense Mode protocol designed to calm an overactive immune response and restore resilience.
Do you feel like you’re constantly catching every cold that circulates?
Does sinus congestion or pressure seem to linger far too long? Is your energy always low, never fully “on,” no matter how much rest you get? These are classic signs that your immune system is stuck in Defense Mode overactive, overtaxed, and underperforming.
Your immune system is overreacting. It's time to reset it.
Start My Defense ResetCommon Signs of Immune Overload
- Catching everything that's going around
- Sinus congestion or pressure that never fully clears
- Slow recovery from illness or stress
- Seasonal allergies or inflammation causing brain fog
- Low-grade energy that never quite feels "on"
“This isn’t just bad luck. Your immune system is stuck reacting instead of protecting. It’s overtaxed, overexcited, and underperforming-and it needs a reset.”- Dr. Steven G.
The Defense Mode Loop (and How We Break It)
Stress, poor sleep, and constant irritants overstimulate the immune system Immune overactivation causes sinus pressure, congestion, and fatigue Chronic exposure keeps defenses overfiring Your system stays stuck in survival mode, not thriving. We can break it.
Immune Overstimulation
Stress, poor sleep, and constant irritants overstimulate your immune system.
Sinus Pressure & Fatigue
Immune overactivation causes sinus pressure, congestion, and fatigue.
Chronic Exposure
Food chemicals, environment, and irritants keep your defenses overfiring.
The GPX Defense Mode Reset
Reset your immune system to stand strong again. Calm overactivation and restore resilience.
We’re going to reset your immune system to stand strong again.
GPX Defense Mode is a 30-day immune reset protocol designed by Dr. Steven Geanopulos to calm overactive immune responses, strengthen resilience, and support faster recovery. This comprehensive formula combines 4 separate supplement blends into two easy-to-take daily sachets-one for the morning and one for the evening.
Morning Pack
Steadies your immune response for daily resilience and defense.
Evening Pack
Helps restore balance during rest, preparing your body for the next day.
What’s Inside GPX Defense Mode
Each sachet in the GPX Defense Mode pack contains clinically-proven ingredients that target multiple aspects of immune function to help your body stay resilient, recover faster, and breathe easier.
Supports Gut-Driven Immune Function
Your gut microbiome is essential for immune health. Biome-GPX helps balance gut bacteria, improving immune resilience and reducing overactivation.
Vitamins A, D, E, K2, Magnesium, and Zinc
These are essential nutrients to support the body’s natural defense function.
Acerola Cherry, Camu Camu, Rutin, Citrus Bioflavonoids
These natural sources of Vitamin C support antioxidant activity and enhance immune resilience.
Helps Break Down Mucus and Ease Congestion
Supports sinus function, helping to clear mucus and relieve sinus pressure, making breathing easier.
Dr. G's Recommended Protocol for Defense Mode
What You'll Do for 30 Days:
Daily Foundation: Take your Defense Pack (formulated to calm overactive immune responses and strengthen resilience).
2 Food Shifts: Add colorful veggies daily (phytonutrients help calm inflammation). Reduce processed “immune irritants” (such as excess sugar, refined oils, and preservatives).
1 Recovery Rule: Prioritize one 20–30 minute recovery practice (such as a walk, sauna, or breathwork) 3 times per week to support immune recovery.
1 Sleep Protector: Commit to a wind-down routine before bed-sleep is immune fuel and essential for daily resilience.
Start the 30-Day Reset"Huge difference! Clearer sinuses and stronger energy. Defense Mode works!"
- Sarah M.

What customers are saying
I live in the Midwest. My energy level seems to be higher since I started taking this.
Great product! I feel better and feel my resiliency improve with using this regularly. That I can even take colds away easily, and it's shelf-stable. What's not to love about this?!
Figured I would give this product a try to help with drainage and inflammation of my sinuses. I am very happy with both! I was amazed! Even told my husband to try it. He was amazed as well. Really works!
Very satisfied.
I am so impressed with this product! I have been using nasal sprays and other over-the-counter treatments to try and combat my allergies and sinus drainage problems. This and AllerAid together have alleviated most if not all of those issues. I have recommended this to everyone I know. Fantastic!
Years ago I went on two rounds of antibiotics for a sinus infection - it didn't do anything besides cause other problems. My chiropractor recommended this product and within a week I felt like myself again. I now recommend to all family and friends!
Helps with immunity.
I always feel good about taking this. It helps the GOOD bacteria in your intestinal tract thrive.
This helps keep my sinus clear and I recommend it.
I love this product. I can tell a difference in my immune system. It's only been 3 days and it's improving every day. Highly recommend this.
