Home hormone tests

Has anyone done a home test kit for hormone levels? I just read the “I Could Just Spit!” article by Joe Ailts and was wondering how the results of a saliva test would be analyzed and used to the benefit of a natural lifter. Also, thehormoneshop.com offers a Cortisol Rythum test which test four samples from four different times of the day. Wouldn’t this information be beneficial to measure once in the middle of the night, at wake-up, mid-afternoon and post training? Then someone could find out when they are falling short, right? Hey… if anyone can tell me IF this is worth it, please do.
