I should report back my experience with using one of these products. After misreading one of TrainerDan's posts, I bought Thyrolean by Prolab (he recommended Thyroslim). It has 15 mg of ephedra in it and only 10 mg of caffeine from green tea, which is unusually low for a thermogenic. The thyroid supporting part is:

gum guggle extract
phosphorous
phosphatidylcholine
garcinia cambogia
L-Tyrosine
citrus aurantium

For a week before I bought it, I compulsively took my temperature throughout the day. It was usually between 96.5 and 96.8. A couple of times it went into the 95 range and once was as high as 97.1.

Once I started taking the stuff, I again took my temperature obsessively. Now I'm usually 97.8 to 98.1 degrees. I go as low as 97.0 and once I actually made it to 98.6! It seems like an improvement to me. I don't know that it will have any big fat-burning effect, but I think I'll keep it up for a while.

I also mean to try something without the ephedra and will let you know my results when I do.
