You can always self-order a testosterone test. In our area CompuNet offers them for $40.

I did that on one occasion. (I recall telling my wife (in late January 2022), that I thought the Eligard was wearing off because I was beginning to lift heavier weights at the gym. Since I wasn’t due for another “official” bloodwork for another couple of months, I self-ordered another PSA & testosterone test (out of curiosity), and those came back as 0.13 & 403.0, respectively - meaning that everything was going exactly as expected (that is, testosterone increasing on schedule & PSA staying low).
