The Quad Defense™ System

Four pathways. One protocol.

Each capsule delivers targeted compounds that address the primary drivers of cellular aging — not symptoms, but root causes.

Telomere Support

Preserves chromosome end caps with Cycloastragenol and Astragaloside IV to maintain healthy cell division limits.

Key compound Cycloastragenol 25mg

Mitochondrial Health

Enhances ATP production and biogenesis through PQQ and CoQ10 — the energy currency your cells depend on.

Key compound PQQ 20mg + CoQ10 100mg

NAD+ Optimization

Boosts NAD+ levels with NMN and Resveratrol to activate sirtuin longevity enzymes.

Key compound NMN 500mg + Resveratrol 250mg

Cellular Protection

Neutralizes oxidative stress with Spermidine and Fisetin while promoting healthy autophagy clearance.

Key compound Spermidine 10mg + Fisetin 100mg

Scientific Foundation

Member Outcomes

Real results. Real people.

Verified members report measurable changes in energy, recovery, and overall wellbeing within 60-90 days of consistent use.

"At 58, I assumed my afternoon energy crash was permanent. After 10 weeks on the protocol, I'm back to my morning workout routine — something I hadn't managed in five years."

Common Questions

Protocol clarity.

Evidence-based answers to your most important questions.

How soon will I notice results?

Most members report subjective improvements in energy and recovery within 3-4 weeks. Measurable biomarker changes — including NAD+ metabolite levels and inflammatory markers — typically appear at the 8-12 week mark. We recommend a minimum 90-day commitment for full cellular pathway engagement.

Are there any side effects?

Quad Defense™ ingredients are Generally Recognized As Safe (GRAS) by the FDA. In clinical trials, mild digestive adjustment was reported by less than 4% of participants during the first week. We recommend taking your packet with breakfast to minimize this. Consult your physician if you are on blood thinners, as high-dose Resveratrol may interact with these medications.

Can I take this with other supplements?

Quad Defense™ is designed as a comprehensive protocol. If you currently take a standard multivitamin, you may discontinue it — our formula covers all essential micronutrients at research-backed doses. Avoid stacking additional NMN, CoQ10, or Resveratrol supplements to prevent exceeding optimal therapeutic ranges.

What is your testing and quality process?

Every batch undergoes identity testing, potency verification, microbial screening, and heavy metal analysis by independent ISO 17025 laboratories. Manufacturing occurs in NSF-registered, FDA-inspected facilities. Final products are held in quarantine until all CoA results are approved by our quality team.

How does the 90-day guarantee work?

Take the full 90-day protocol as directed. If you don't experience meaningful improvements in energy, recovery, or overall wellbeing, contact our concierge team for a full refund — no return shipping required, no questions asked. We keep only 0.3% of our revenue from refunded subscriptions.
