What blood tests would be reccomended for someone trying to hammer out low testosterone issues? Obviously Test and Free Test. What kind of thyroid stuff should be check for? TSH? LH? Anything else?
TSH, LH, FSH, Lipid panel, you may want a complete blood count (CBC)
In addition to what has already been said, prolactin and maybe sex hormone binding globulin (SHBG) but you need to find a competent endocrinologist.
