3.       We note your response to prior comment 26 and revised disclosure.
Please revise to
         provide the basis for your belief that your "methods will enable [you]
to create new
         natural psychedelic medicines in the near term." Please also clarify
that these medicines
         will still be subject to the regulatory approval process and that
development of these
         medicines could fail. Finally, please tell us how your statement that
you will develop these
         new psychedelic medicines in the "near term" is consistent with your
statement that you
         do not have material research and development programs other than for
psilocin and
         psilocybin.

number of patients,
         how patients will be selected, the number of times that patients will

         patients will also receive psychotherapy as a part of the trial and
whether the trial will
         include a placebo component.

Please revise the

NeoLumina
       Bioscience and Reset Pharmaceuticals are both in the planning stage.
However, the status
       bar for each of these trials in the "Select Customer Contracts" graphic
