The basic info on my health, rating my health by age, and the details. But all the information on more blood tests surprised me and could have added another $1,500 to my cost. Needed to know about these " add-ons" before the second draw to better evaluate value and need.

Thank you for sharing this feedback and for being a member, John. We're glad the core health insights have been valuable, and we hear you on the surprise around add-on testing costs during your second draw. That kind of transparency matters, and we want members to feel fully informed before deciding on any additional tests. We'll make sure this is passed along to the team so we can improve how add-on options are communicated in advance.

I like the ability to get a lot of info via the blood testing, as well as getting recipes for all meals for a week and other perks, but it is IMPOSSIBLE to speak to a human. I guess not 100% impossible, but pretty close to 100% impossible. I tried to contact an actual person because I couldn’t get anywhere with the AI bot, and I was ‘told’ that an actual person would call me back. Nope, never happened, nor did the bot give me a time that the actual person would call me back. If you hate dealing with bots, you will probably be happier working with a company that employs actual humans. If I knew that they were using a bot to answer questions I never would have signed up. I prefer to work with companies that actually care about the future of our country and employ actual humans within our country.

Hi Sarah, thank you for sharing this, and we're sorry to hear about the frustration of getting in touch with a real person, especially after being told you'd receive a callback that never came. That's not the experience we want members to have, and we understand how discouraging it is when support feels out of reach. We've sent you an email directly so our team can assist you further.

One of my tests had to be redone, and the process for getting that done was seamless.

Fast results with details and clear explanations. I really appreciate the data point connection to my previous lab results. I also like the suggested ways to improve. Thank you FH. I am now 16.2 biological years younger and know what I still need to improve and now know how to continue to improve. Having clear data is the starting point of being intentional of optimizing one's health.
