CordyMax Cs-4® Bottle (USA)

CordyMax Cs-4® — Standardized Cordyceps for Stamina, Energy & Oxygen Utilization

Cordyceps sinensis has been one of the most valued medicinal mushrooms in traditional Chinese medicine for over 1,500 years — prized by everyone from Tibetan yak herders (who noticed their animals became more energetic after grazing on cordyceps-containing pastures) to Chinese Olympic coaches (who credited it for their distance runners' world records in the 1990s). CordyMax Cs-4 is Pharmanex's standardized cordyceps extract, produced using a specific strain (Cs-4) developed by Chinese Academy of Sciences researchers for verified bioactivity and consistency.

Wild cordyceps is extraordinarily expensive (over $20,000 per kilogram) and wildly inconsistent in quality. The Cs-4 strain solves both problems: it's produced through controlled mycelial fermentation that yields a standardized extract with documented levels of the bioactive compounds — cordycepin, polysaccharides, and adenosine — at a fraction of the cost of wild cordyceps. This makes therapeutic-dose cordyceps supplementation accessible for daily use. 120 capsules per bottle, 30-day supply.

Key Benefits

• Oxygen Utilization Support — Research shows cordyceps can improve VO2 max and how efficiently your body uses oxygen during physical activity. Better oxygen utilization means better endurance, less fatigue, and improved recovery
• Stamina and Physical Endurance — Supports sustained physical performance without stimulant side effects. Cordyceps works by improving your cells' ability to produce energy, not by masking fatigue
• Mitochondrial ATP Production — Supports the cellular energy factories (mitochondria) that power every physical and mental function. More efficient mitochondria = more available energy at the cellular level
• Adaptogenic Stress Resilience — As a true adaptogen, cordyceps helps your body maintain homeostasis under physical, mental, and environmental stress — performing more consistently regardless of conditions
• Respiratory Function Support — Traditional use for lung health is supported by research showing cordyceps may improve oxygen uptake and respiratory efficiency

Key Ingredients

CordyMax contains a single, well-characterized ingredient: standardized Cordyceps sinensis Cs-4 extract. The simplicity is intentional — this is a dedicated cordyceps supplement, not a multi-ingredient blend.

• Cordyceps Sinensis Cs-4 Mycelial Extract — The Cs-4 strain was developed through a Chinese Academy of Sciences research program to identify the most bioactive cordyceps strain for commercial cultivation. It's produced via submerged fermentation — growing cordyceps mycelium in a controlled liquid medium that produces consistent bioactive compound concentrations. The resulting extract is standardized for cordycepin (a nucleoside analog with documented biological activity), polysaccharides (immune and energy support), and adenosine (cellular energy currency precursor)
• Cordycepin — A modified nucleoside unique to cordyceps with documented effects on cellular energy metabolism and oxygen utilization. Research in the Journal of Dietary Supplements showed that cordycepin-containing extracts improved exercise performance markers in healthy adults
• Adenosine — A precursor to ATP (adenosine triphosphate), the primary energy molecule in human cells. Cordyceps is one of the few natural sources that provides adenosine directly, supporting the raw materials for cellular energy production

How Nu Skin's Approach Differs

The cordyceps supplement market is divided between cheap, unstandardized mushroom powder products and expensive wild-harvested cordyceps with inconsistent quality. Pharmanex's CordyMax occupies a different position: a rigorously standardized extract from a scientifically validated strain, produced under pharmaceutical-grade quality controls.

The Cs-4 strain selection is key. Not all cordyceps strains are equally bioactive — the Cs-4 strain was specifically selected after comparative analysis by Chinese Academy of Sciences researchers showed it produced the highest levels of the compounds responsible for cordyceps' traditional benefits. The fermentation process is controlled for temperature, pH, nutrient medium, and growth duration to ensure each batch meets standardized compound specifications.

Under the 6S Quality Process, each batch is tested for bioactive compound content (cordycepin, polysaccharides, adenosine), heavy metals, microbial contamination, and identity verification. For mushroom products, identity testing is particularly important — there have been documented cases of cordyceps products containing different (less effective) fungal species.

How It Compares

Comparison based on publicly available product information as of 2025. Features and formulations may change.

How to Use

Take 4 capsules daily — 2 in the morning and 2 in the evening with food. Consistent daily use over several weeks delivers the best results. Athletes and physically active people may notice improvements in stamina within 2-3 weeks. This supplement works gradually by supporting biological energy pathways, not through stimulation. The 120-capsule bottle provides a 30-day supply.

Who Should Consider This Product

CordyMax is well-suited for athletes and active adults seeking non-stimulant performance support, professionals who need sustained mental and physical energy throughout demanding days, adults over 40 experiencing the natural decline in stamina and exercise tolerance, and anyone interested in traditional Chinese medicine approaches to vitality backed by modern standardization and quality testing. Not recommended for those with mushroom allergies. If you're on immunosuppressant medications or blood thinners, consult your healthcare provider.

Frequently Asked Questions

Q: Is CordyMax a stimulant?

A: No. It contains zero caffeine or stimulant compounds. CordyMax supports your body's natural oxygen utilization and cellular energy production — it's an adaptogen, not a stimulant. You won't feel wired, but over 2-3 weeks you may notice better endurance and less fatigue.

Q: What's the difference between CordyMax and the cordyceps in ageLOC R2?

A: Both use the same Cs-4 cordyceps strain. CordyMax is a dedicated cordyceps supplement for stamina and vitality. R2 uses cordyceps as one component of a broader gene expression formula. They can be used together — CordyMax for additional stamina support alongside R2's cellular renewal benefits.

Q: Can competitive athletes use this?

A: CordyMax contains no banned substances. However, competitive athletes should always verify any supplement against their sport's current prohibited substance list, as banned lists are updated periodically.

Q: Why is the Cs-4 strain important?

A: Not all cordyceps strains are equally effective. Cs-4 was specifically selected by Chinese Academy of Sciences researchers after comparative testing showed it produced the highest levels of bioactive compounds among cultivated strains. Using a validated, standardized strain means predictable, verified potency in every batch.

Q: How long does one bottle last?

A: At the recommended dose of 4 capsules per day, the 120-capsule bottle provides a 30-day supply.
