In general satisfied with initial and mid year tests and biomarkers provided. I live in a rural area and had to drive 2 hours for a Quest blood draw site. AI chat added midyear to the website was helpful in recommending supplements . Moving forward I feel I can do limited testing for out of range biomarkers elsewhere for more reasonable cost. without all the bells and whistles of the annual renewal. Removing my yearly auto renewal seems to be more of a process than it should be
