Joachim nailed it. KCFA and CTAHR have both asked Symbiotic for their data to back up the stated results. No response. Most of the “testimonials” seem to come from people who have a financial interest in the product (either they were given it free or are marketing it).
I know people are willing to try anything that might work. As with any product, do the 30 Trees, try the product, then do the 30 Trees again.
