Decode peak performance with bio-cellular precision.

Clinically-Proven Molecules
Urolithin A, spermidine, and SAC backed by gold-standard RCTs in strength, endurance, and mitochondrial health.

Triple-Pathway Activation
Supports mitophagy, autophagy, and antioxidant defense the three pillars of musclespan and cellular longevity.

Bioavailable Performance Doses
Clinical-grade formulation delivers 1000mg Urolithin A, 6mg spermidine, and 1mg SAC at efficacious levels.

Proven in Middle-Aged Adults
+12% muscle strength, improved peak VO₂, enhanced endurance, and reduced inflammatory markers vs placebo.

Unlike many muscle‑centric pseudoscience supplements, M3 is built for Musclespan the cellular capacity to produce energy, recover, and keep output high as you age.
These cellular batteries start wearing out in your 30s.

Peak Endurance
Benefits that build over time
Your cells adapt before your mirror does.
Cellular Programming Begins
- Urolithin A reaches target plasma concentrations
- PINK1/Parkin mitophagy signaling activates
- Skeletal muscle mitochondria prioritized for quality control
Cleanup Pathways Online
- Mitophagy clears damaged mitochondria
- Autophagy eliminates protein aggregates
- Training recovery becomes more predictable
Mitochondrial Efficiency Shifts
- OXPHOS protein expression increases
- Acylcarnitine levels begin declining
- Cellular adaptation accelerates with consistency
Performance Thresholds Move
- Muscle endurance improves (RCT: +20% contractions-to-fatigue)
- Fatigue resistance increases at intensity
- Musclespan capacity expands measurably
System-Level Optimization
- Inflammatory markers drop (CRP -40%)
- Mitochondrial stress signals decline (acylcarnitines, ceramides)
- Triple-pathway protection sustains cellular health
Compound Longevity Returns
- Muscle quality preservation across loading cycles
- Performance capacity maintained decade-over-decade
- Cellular aging rate slows at the mitochondrial level


How to Use:
Take 2 capsules daily, with or without food, day or night.

Day-to-day life can disrupt the balance of your muscle mitochondria, depleting your critical super defendermitochondrial quality control.
























Built on Celagenex’s Research
MP M3 emerged from mitochondrial health discoveries of Urolithin A, Spermidine, and S‑Allyl Cysteine strains that defend the muscle-span biome from aging, stress, and metabolic imbalances.

Patented M3 Delivery
M3 delivers patented, bioavailable actives with 95%+ cellular uptake, ensuring mitochondrial, muscle, and brain targets receive full clinical doses intact unlike standard capsules that lose 70–90% in digestion.
Urolithin A 500mg™: Clinically proven mitophagy activator; boosts endurance 41-95% in RCTs

Why M3 is Superior to NMN
M3 prioritizes mitochondrial quality (mitophagy biology) with human RCT signals in muscle endurance + mitochondrial biomarkers, while NMN primarily boosts blood NAD+ with mixed/limited functional signals and no meaningful body-composition change.
Urolithin A 1000mg
Clinically-proven mitophagy activator. RCTs show improved muscle endurance, reduced inflammation, and enhanced mitochondrial health in adults 40-65.*

ACTIVATION TIMELINE
Plasma levels peak at 2-4 hours. Mitochondrial remodeling occurs over 4 months.*
Spermidine 6mg
Autophagy inducer for cellular cleanup and muscle recovery. Synergizes with Urolithin A for complete renewal.*

ACTIVATION TIMELINE
Absorbed in 1-2 hours. Autophagy activates within 4-6 hours. Full benefits accumulate over 8-12 weeks.*
S‑Allyl Cysteine 1mg
Nrf2 antioxidant that enhances glutathione for vascular and neural resilience under training stress.*

ACTIVATION TIMELINE
Peak plasma at 30-60 minutes. Nrf2 activation begins within 2-4 hours.*
Clinically Validated Efficacy
Results from randomized, double-blind, placebo-controlled trials on M3 key ingredient Urolithin A:
Of participants established stable mitochondrial function (reduced acylcarnitines/ceramides)
Increase in mitophagy markers within 21 days use
Of participants maintained optimal muscle endurance gains
