33-1 refers to the ratio of testosterone and epitestosterone in the body. Epitestosterone is an inactive epimer of testosterone which produced in similar quan****** in most people.
The T/E ratio test is an outdated and cheaper way to test for exogenous T. The idea is when u add T to your body there won't be additional E so the ratio will rise.
A normal ratio is about 1.15:1 but some people naturally have much higher ratios up to around 5:1 but that's very rare.
Because of this, athletes are allowed to have a ratio up to 4:1 without failing.
The reason this test is outdated is that athletes can take T and get a boost and stay just below the 4:1 and you can take E to keep the ratio down anyway.
A much better but more expensive test is a carbon isotope ratio test, which can find even small amounts of artificial T because It's made from plants rather than natural steroids such as cholesterol. As plants have more C13 carbons than are found in natural steroids, there is a higher ratio in the T.
Thanks was trying to understand it all, when I read 33:1 I read it as Ana/Andro which made me think, wait what that's a terrible ratio. I don't know much on specifics on the testing in sports so your info was helpful.
