Dennis was showing off that vial at the biomass conference and at the HB counsel meeting, both times he said that little bit was worth 45K. IIRC at the biomass conf. he said it was the condensed product from 1 pound of spirulina. I was impressed!!!
Phycocyanin is available in different grades/quality indexes Right from the food grade to analytical grade. It could be as cheap as 500 USD per KG to 100,000 USD per gram. All depends on quality. Much like many other products.
