Ray,
I certainly understand a Company not wanting to reveal the percentages of each ingredient, how it is prepared, etc. but I do find the "contents" information on the MycoGrow and Biota Max website about what is in their products comforting and informative in purchasing their products. I am always leery when a Company doesn't even show their list of ingredients for the consumer to evaluate.
Nevertheless, let's see how the sample trials produce results. If the Thrive product exceeds that of the much less expensive Biota Max or Myco Grow at $6.00 including shipping - then I will be a "fan".
