Hormonal test advice to track post-treatment changes

I’d like to start with finastride treatment but before I do that, I’d like to run some blood tests so I can track my changes after starting the treatment. However, I am unsure what kind of test I should do and what exactly I should track (I guess some hormones?). What should I look for?

Track DHT, testosterone, estradiol, and SHBG levels. These will show how fin affects your hormones. Each can give you insight into how the treatment is impacting your system.
