Myths vs facts: Testosteron Test and Sport

Myths vs facts about testosterone testing in sports: A common myth is that a DNA test (e.g., from MyBody-X) can measure your current testosterone level. Fact: DNA tests analyze genetic variants, not blood hormone concentrations. A blood test is required. Another myth is that high testosterone automatically leads to better athletic performance. Reality is more nuanced: testosterone influences muscle growth and recovery, but factors like training, nutrition, sleep, and other genes (e.g., ACTN3) are equally important. Moreover, excessively high levels (e.g., from doping) can be harmful. The idea that testosterone tests are only for bodybuilders is also false; they are used medically to diagnose hypogonadism or other hormonal disorders. Evidence shows that genetic predispositions (e.g., in the androgen receptor gene) can affect sensitivity but not current levels. If you want to know your testosterone level, consult a doctor for a blood test. Direct-to-consumer tests do not provide reliable data for this purpose.
