Esters and blood work. What are you really getting?

[Pantalones]

I was wondering if anyone could tell me if it is only testosterone and its chemical composition alone that is detected in a testosterone lab analysis. I'm talking for the specific purpose of testosterone replacement therapy, and the fact that the testosterone is attached to an ester to allow for a slower release. I'm wondering if the testosterone attached to the ester shows up, or only the testosterone free of the ester will show in the results. Especially when dealing with free T, I would assume the lab would need to be specific in their findings, and only the non-esterised T would be included.

The two differ in chemical composition, so I'm assuming they would.

Thank you.

Testosterone + esters are not detected in a lab analysis.

Testosterone + esters are not detected in a lab analysis.

So neither testosterone or the ester is detected. Or what you mean is, the testosterone is, esters are not?

Testosterone attached to the ester is not detected, remember the ester makes the Testosterone+Ester complex fat-soluble . Testosterone is detected as free or bound to SHBG.

Oh, I understand! So the t+ester remains in adipose until the ester is cleared.

It remains in "depot" yes. Unless you inject subQ but then I guess it remains in depot in the adipose.

Thank you!!! Very helpful
