C4HXP Program Overview
Explore the choices, at-home experience, and result access that shape the C4HXP program.



Our offerings allow you to measure key health markers, such as hormone levels, heart health, essential vitamin levels, and liver and kidney function.
Once you decide what you want to test, you can complete your test on your time schedule without worrying about appointments or waiting rooms.
The price listed is the price you pay, with no hidden fees, insurance approvals, claims, or deductibles.



Eligible C4HXP kits use the Tasso device, a state-of-the-art upper-arm blood collection device designed to make collecting your sample at home more convenient and less painful.
Our at-home blood collection kits are discreetly delivered to your front door. Samples are returned with a prepaid shipping label for ultimate convenience.
Samples are processed by our CLIA-certified lab partners to ensure the accuracy of your results.



Your results will be available 1-3 business days after your kit is received by the lab.
Your results will be immediately uploaded to your private digital wellness dashboard after lab processing to be reviewed from anywhere, at anytime.
Your results belong to you. Share them with your healthcare provider to support a future conversation.
