Currently one of the most used and reliable ways in doping controls to detect exogenous testosterone consumption is the relationship between testosterone and epitestosterone (T / E RATIO).
The normal range for a person who does not exogenously introduce testosterone into her body is 1/1, and it can even be 4/1 depending on genetic factors.
The WADA in its doping controls uses the 4/1 marker to determine if a person consumes testosterone exogenously and when this ratio is higher it considers it positive in the test.
It is true that athletes consume a supraphysiological dose of testosterone to increase their performance, which produces an increase in the testosterone indicator, but by not altering the epitestosterone value, it causes the ratio to increase to very high levels (for example 17/1)
My question is this:
If a person who is currently on TRT, with a physiological dose of testosterone (for example 100mg weekly of testosterone cypionate) only uses it to maintain values in normal ranges in her body,
Would the E / T ratio be affected in a urine doping test?
By introducing any amount, even to maintain the normal ranges of testosterone in the body, of exogenous testosterone and to slow down natural production, would it also decrease the epitestosterone created naturally by the body and also increase the E / T range?
Could a person who is on TRT only to maintain normal values and not to increase her performance pass a doping test? Since despite introducing exogenous testosterone into your body, the free testosterone values in the body would not be different from those of a “natural” person and therefore would not have any advantage in competition.
Thanks a lot!
