Can anyone explain the logic of using TMZ along with L-carnitine? Wouldn’t they counteract each other? And wtf is hypoxen?

I should say that she was recently banned for 4 years because she claimed the drug entered her system through a cake her grandpa made. Court didn’t find proof that she doped but the excuse was ridiculous so they banned her anyway.

Any Russian literature that promotes the use of all three for better endurance or is it all bullshit?
