Field notes
The homepage separates a study’s questionnaire result from its objective group comparisons, noting that the two did not point to the same conclusion. It also contrasts a displayed $64.99 monthly charge and $195 three-month total with an $80 one-month offer, while cautioning that the supplied preparation’s percentage lacks a verified analytical definition. The publication says its work is based on public records, not assays, patient testing or clinician sign-off.
