Cordyceps-MRL is sourced from Nepal's master strain of the species. Its powder contains a blend of mycelium and immature fruit bodies cultivated on a sterilised medium, ensuring purity and a lack of contaminants. Utilising a proprietary system, its production is standardised—not coming from a dead caterpillar like Cordyceps sinensis from the Far East. Instead, potential contamination by bacteria or fungi is avoided.
