At-Home Testosterone Test

Get quantitative testosterone results in just 10 minutes — no lab visits, no mail-in kits

Inside the CaDI Technology

10 Minute Results, No Lab Sendout

Move beyond one-time lab snapshots. Monitor your testosterone over time with fast, quantitative, fully at-home testing.

  • Each test produces a precise numerical result that you can track over time. The dedicated reader digitally analyzes the assay signal, reducing variability and eliminating the subjectivity common in visually interpreted strip tests. This allows for more consistent measurements across repeated tests, helping you monitor trends with confidence.

  • Our testosterone test runs on CaDI, a next-generation technology built for greater accuracy. It’s more than 100 times more sensitive than traditional rapid tests, enabling lab-quality results in an easy to to use format.

  • Testosterone levels shift with sleep quality, stress load, training intensity, nutrition, and hormone therapy. A precise numerical result allows you to monitor trends over time rather than depend on one isolated reading, making the system ideal for consistent tracking and lifestyle optimization.

  • No lab visits. No mail-in samples. No external processing.
    Everything needed to run the test is included in the kit. The assay runs inside a sealed cartridge, and the reader generates your result in minutes. This allows you stay in control of when and how you test, without depending on third-party labs or delayed reporting.

  • High sensitivity does not have to mean complicated. CaDI powers a straightforward, guided workflow that makes precise testing simple and efficient. The companion app walks you through each step, captures your results instantly, and helps you track changes over time, so advanced performance feels intuitive from start to finish.

  • The reader seamlessly pairs with a dedicated app, giving you instant access to your testosterone results from your smartphone. You can track trends over time, compare past tests, and visualize how your levels change. The app also allows you to log symptoms, sleep, training, nutrition, and other lifestyle factors alongside each result. By combining precise measurements with real-world context, you gain a clearer understanding of what is influencing your testosterone levels and how to adjust accordingly.

  • Each cartridge is inserted into a dedicated reader that captures the test signal and converts it into a precise testosterone value displayed in the app. Instead of relying on faint lines or visual guesswork, the reader measures the chemiluminescent signal produced by test, allowing for much higher sensitivity than traditional rapid tests.

    Because the result is precisely measured, not visually interpreted, you get a clear result you can trust with greater consistency.

Testosterone Changes. Your Testing Should Too.

Testosterone is a critical hormone in men’s health, influencing energy, body composition, bone density, cognition, mood, libido, sleep quality, and overall vitality. Because it plays a role in so many systems at once, even gradual shifts can affect how you feel, recover, and perform over time.

Testosterone levels typically peak during adolescence and early adulthood, then gradually decline with age for many men. Research suggests levels decrease on average by about 1 to 2 percent per year after age 30. For most adult men, total testosterone levels generally fall within a range of approximately 300 to 1000 ng/dL, though “normal” can vary based on age, health status, or other factors. Levels below 300 ng/dL are often classified as hypogonadal, which refers to clinically low testosterone and may be associated with symptoms such as fatigue, reduced muscle mass, lower libido, and decreased overall vitality.

Natural Fluctuations Overtime

Importantly, testosterone is not static. Levels fluctuate broadly with age, but they also vary throughout a single day. In most men, testosterone peaks in the early morning, typically between 7–10 a.m., and declines throughout the afternoon and evening. Various activities such as sleep quality, stress, or activity levels, can further influence production. Due to these natural fluctuations, aligning testing with peak timing is important for obtaining meaningful results.

Limitations of Traditional Testing

Despite natural variability, most testosterone testing is built around infrequent lab measurements. Getting tested through a lab often requires appointments, waiting rooms, time off work, and higher costs. As a result, many men only test a few times per year, if at all. This frequency makes it difficult to observe real trends or understand how lifestyle changes may be influencing hormone levels over time

CaDI: Better Hormone Insights

Many “at-home” kits still require lab send-out, cost $60–$150 or more per test, and take days to weeks for results. These barriers limit repeat testing, making frequent monitoring impractical.

Our fully at-home testosterone test eliminates these barriers. CaDI allows you to retest on your schedule, from home, and monitor how sleep, stress, training, and lifestyle choices are impacting your hormone levels.

Understanding The Impact of Testosterone

Energy

Testosterone helps signal the production of red blood cells and influences metabolic processes linked to energy. Testosterone also supports mitochondrial function, allowing the body to convert nutrients more efficiently into energy. Low testosterone levels are linked to sleep quality, which can contribute to fatigue in some men.

Muscle Mass

Testosterone plays a key role in building and maintaining muscle by promoting protein synthesis that supports lean body composition. Studies indicate that higher testosterone levels can increase muscle mass and decrease fat mass, whereas low levels are associated with muscle loss and increased fat mass.

Mood

Testosterone also influences the brain through its effects on neurotransmitters, which can play an instrumental role in mood and mental health. Research indicates that atypical testosterone levels may be associated with depression, brain fog, irritability, or reduced drive in some men.

Sexual Health

Testosterone has a significant influence on sex drive, erectile function, and even sperm production. In men with low testosterone, clinical studies show that bringing levels back into the normal range can significantly improve libido and mild erectile dysfunction.
