Testosterone/Cortisol ratio
The Testosterone/Cortisol ratio reflects the balance between anabolic (building) and catabolic (breaking down) processes in the body. Testosterone supports muscle growth, energy, and recovery, while cortisol is a stress hormone that can promote tissue breakdown when chronically elevated. A healthy ratio may indicate good resilience, recovery capacity, and hormonal balance, whereas a low ratio may suggest high stress levels, overtraining, or hormonal imbalance. This marker is particularly relevant for athletes, individuals under chronic stress, or those with fatigue-related symptoms. It helps provide context to both testosterone and cortisol values when interpreted together.
Description
There is no universally defined “ideal” ratio, as values can vary based on age, sex, time of day, and individual physiology. However, a relatively higher ratio is generally associated with better anabolic balance, while a low ratio may indicate stress dominance.
A low ratio may indicate increased physical or psychological stress, overtraining, poor recovery, or suppressed testosterone levels. It can signal that the body is in a catabolic state and not recovering optimally.
Yes, the Testosterone/Cortisol ratio is dynamic and can be influenced by factors such as sleep, stress, training load, nutrition, and recovery. Tracking changes over time can provide insights into how your lifestyle is affecting your hormonal balance.
Looking at the ratio provides a more holistic view of the body’s stress and recovery status than each hormone individually. It helps detect imbalances that might not be obvious when looking at just one hormone in isolation.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
