Results Explained
  • Superior Purity: Our Cordyceps liquid contains less than 1% starch, while competitors range between 22–77%.
  • Better Absorption: Our liquid formulas are designed for maximum bioavailability, meaning your body absorbs nutrients more easily.
  • Trusted by Athletes: Certified safe by Informed Sports, giving you confidence in our products.

*lodine Grain Test: When iodine is added to a mushroom/water solution and if it turns black/purple, then the mushroom product is high in starch and doesn’t meet purity standards. You can even try this at home to see the difference!

*Purity Starch test %: Our products undergo three independent lab tests and achieve an average starch content of less than 1%. This industry-leading pass rate ensures you get the highest quality mushroom extracts.
