Great Company, Excellent Customer Service, Reliable Results! I had lower expectations, but I received my report within two days and they were easy to read. They went out of their way to measure additional compounds for free. I’m so thankful to them for their affordable service.
SatisfiedCustomer –
Exceeded expectations. I was a bit hesitant especially since some reviews said they did not get their results, but it is May 2022 and I received mine. I also received a quick reply when I had checked on the status at around 2 weeks after sending my sample. It took about 3 weeks total for my results. They included more testing than I had expected, too. I am planning on taking the results to the doctor to look into some things more. I am very appreciative of this service and that they tested for more than what I had actually suspected, it is really helping me get some answers.
Stephanie –
Very good and fast test! Results come in my email in a few days and I took them to my doctor.
Alaina –
Amazing. They have good customer service and the test helped me so much
Mario –
After going to many doctors, including specialist and not being able to find why I was experiencing certain symptoms, I came across this test online. When I ordered it I had no idea how detailed it would be. My one level was very low and now I have an appointment in 2 weeks to try to get help for this. I recommend this to anyone because it was so easy and so worth the money spent.
Daria –
Excellent lab and customer service! They performed extra tests, and uncovered my mysterious illness that non of the 13 specialists I’ve been seeing could. I can’t thank them enough. I’m so thankful that self services like that exist. As a lesson, always do your own research and self tests, don’t trust your health to those who say you have anxiety or don’t care to investigate any further! 🙂
Holly –
Missed the results in my email but they re-sent them as soon as I requested.
Mark –
Unexpected professionalism. You receive a bunch of extra information that is extremely helpful. Very good communication with this company. I honestly don’t know what they could do any better for the money.
Jason –
The provider went above and beyond by providing me a report on other hormone levels as well as my cortisol level and did so in a very prompt manner. Unfortunately, I had a little issue with shipping because the provided stamp didn’t completely cover the shipping costs. Still, the value of this product was well worth the cost of the product and the shipping.
Sarah –
Impressive! The results are much more comprehensive than most at-home lab tests, especially for cortisol. They really break down in

I was unsure when I purchased it but when I got the results they were easy to read and understand. The results confirmed what there was something wrong with me when doctors kept telling me there’s nothing wrong. Thank goodness for this test.

I was surprised how easy it was to do this test. It’s very straight to the point in that you order it follow the simple instructions and send your sample back. Within a short period of turn around time they email you a detailed report of your results. Highly recommend due the simplicity of the process. 5 stars.

JP –
They did a nice job. The lab report is very detailed. In fact, the test and report provided information that my doctors never mentioned or tested for before. So, I highly recommend this service as it will save a lot of money for you and provide more detailed results than your clinic’s lab will usually provide. I will now go back to my doctors and show them these results.
