Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
No. The $250 test covers identity, purity and quantity by HPLC-UV measurement of ganoderic and ganoderenic acids, with LC-MS identity. Full testing to the USP Herbal Medicines Compendium monograph for Ganoderma lucidum Fruiting Body is available and quoted.
The monograph standardizes reishi fruiting body to the sum of ten ganoderic and ganoderenic acids, which can be measured individually by HPLC. Polysaccharide and beta-glucan claims need a separate method and are quoted separately.
Mycelium grown on grain usually has much lower triterpene acid content and can contain a lot of starch from the grain. The triterpene profile helps tell fruiting body material from mycelium products.
Usually sliced or powdered fruiting body, hot water or dual extracts, or capsules. Water-only extracts tend to be low in triterpene acids, which shows up in the result.
