This year (2019) Promethease revised their report to delete many items. Reportedly his was due to FDA suggestion/pressure. Apparently they deleted some SNP's/reports that involved/suggested drug/supplement usage.
I found this when I went to update my Promethease report before their transition to the new company in November of this year. My 2015 and 2017 Promethease reports were similar with some updates. The 2019 report was substantially different with about 1/3 of what I considered the significant items deleted/not longer reported. Searching the 2019 Promethease report for the specific missing SNPs turned up nothing.
I also did the Rhonda Patrick report. I compared it to the 2019 Promethease report and it was different. This is what led me to check prior Promethease report and discover the differences. The reason for the differences ( i.e. FDA) was found on an internet blog, so it's not for sure.
I found the earlier Promethease reports to be useful and reasonably understandable - with further research. Two things I liked are their Magnititude rating and the Frequency value which are missing (as I recall) from Rhonda Patrick's report.
In short - don't discard your older Promethease reports.
