My only suggestion would be to have assays performed for microbiological content and USP heavy metals. Then I am sure everyone would buy this from you.
How much would that lab charge for these two tests? Analytical Labs in Anaheim charges only $80 for a USP heavy metal test. As far as microbiological, I am not sure of that charge.
