To answer your question, externally administered Testosterone will send a signal to the HPTA that Testosterone is present, subsequently reducing ones LH levels. (Lut. Hormone)
SHBG (Sex H. binding globulin) will also be significantly reduced.
As for a test to “identify” exogenous testosterone, no, as it’s bioidentical. One could however take multiple tests during a span of time to examine fluctuations, but again it depends on what ester the Testosterone was.
Hopefully that helps!
Yes:

Thanks for the more scientific version of part of what I said.
It should make for some caution with regard to supplemental T, UNLESS the natural T readings, before any supplementation, are far far below normal for someone’s age.
