Find the right time of day for your training and exercise
This product includes four sampling vials to measure your anabolic/catabolic hormone ratio (Testosterone/Cortisol) across the day (total hormone analyses: eight). The aim is to identify a solution optimal for you to identify your optimal time of day for your workout.Learn more.
Good hormonal balance means good exercise routines. The Circadian anabolic/catabolic ratio test kit includes an analysis of Free (unbound) Cortisol and Testosterone across the day. Testosterone plays a vital role in creating muscle mass, improving bone density and increasing cardiovascular health. Cortisol, on the other hand, is known to have a catabolic effect on tissue with an associated decrease in anabolic (muscle growth) hormones and suppressed immune function. The optimal hormonal environment for maximal muscle growth (or minimal muscle loss) is when testosterone is high and cortisol is low. Both these two hormones follow a diurnal, or circadian, cycle whereby they sharply increase in the morning to their maximum peak, and then decrease throughout the day, reaching their minimum again at night. If you choose to use the test to assess your diurnal secretion, remember that cortisol increases in function of stress; and testosterone may also increase in some males during or after a competition, so try to choose typical days (one that is common in your current life situation) for your testing.
DHEA (Dehydroepiandrosterone) is sometimes dubbed the anti-aging hormone. It is an anabolic compound that can buffer the negative effects of cortisol on several bodily functions and illnesses and can protect against burnout, Alzheimer's, and migraine. DHEA-s (Dehydroepiandrosterone sulfate) is the sulfated form of DHEA, which represents close to ninety-eight percent of the total circulating DHEA in our body. DHEA-s also shows less of an inter-individual variance (both from one day to another, or different times of the day), and is not easily affected by stressors, making testing of DHEA-s more suitable than DHEA as a health biomarker. Correspondingly, the ratio of DHEA-s over Cortisol often has a stronger effect size on illness than either of the two hormones alone. To obtain saliva for this test, you provide one sample only. Your results will present a reference range as well as an overview of the importance of Cortisol/DHEA-s for health markers.
The testosterone to cortisol (T/C) ratio is used to assess physiological strain and recovery after exercise. As testosterone is an anabolic hormone and cortisol a catabolic hormone, this ratio is often referred to as the anabolic ratio, and measurement is pivotal for endocrine homeostasis during acute and chronic exercise. Indeed, it has been proposed to be linked to overtraining. Recent research also shows that this ratio is of importance to female athletes.
This test involves performing four saliva samples surrounding a work-out session (immediately before, immediately after, 1 hour after and finally 12 hours after a session). From your four samples, we extract both cortisol and testosterone, yielding a total of eight analyses. Benchmarking your levels before exercise, this test is above all to be used for intra-individual analysis. The reference range for overall testosterone and cortisol are provided, and your T/C parameter will be placed in relation to published literature using this ratio.
