Below is a recommended hormonal panel to evaluate the effect the drug is/was having on your body, comprised of certain hormones typically affected by the Post-Finasteride Syndrome. Since nobody knows every single hormone the drug affects by inhibiting the 5AR pathway, it's important to get as big a picture as possible.

If you are considering taking Finasteride (not recommended), we advise you to get BASELINE blood tests so you'll have results to compare against in the future, should things go disastrously wrong while on or after quitting the drug.

... and hopefully LFT and CBC for overall health picture.
