Dr. Charles Runels, MD
If you want your blood analyzed for optimum hormone and metabolic levels as suggested in my book, Anytime...for as Long as You Want: Strength, Genius, Libido & Erection by Integrative Sex Transmutation, or in my tape Fine Tune Your Female Body, then I can provide testing for you wherever you live in the USA (click here to find the closest facility). These are blood tests (which are more accurate than saliva testing).
For an example of some of the strategies that may help you, here's a sample of some of the strategies to optimize thyroid hormone replacement (which only works well if done in conjunction with the optimization of other hormones).
You can order the lab work here. You will receive a phone call within 2 business days of your order. This call will be to arrange for someone to come to your home or business to draw your blood (price includes this service). Results will be available within 17 business days.
