Saliva testing

Another disappointment for the Lee crowd. Seems saliva testing for progesterone like everything else about the miracle cure won't hold up when tested in a real laboratory.

Leigh,

I'm sorry, I don't know what site you mean. Can you be a little more specific?

RE: Saliva testing

I thought that you mentioned a site one time that shows about menopause without hormones......I could have the wrong person though.

RE: Saliva testing

Perhaps you mean tishy's site? That's at:

http://www.oxford.net/~tishy/beyond.html or you can just click below. This site is far more than just a site about dealing with menopause without hormones. It has a wealth of information and links to other places with more information. It is also totally non-commercial since it accepts no advertising and sells nothing.

I hope you find it useful

Here is a link that might be useful: http://www.oxford.net/~tishy/beyond.html
