Thyrolean works by stimulating your body's thyroid ... a more active thyroid = higher metabolism.

The active ingredient in many of the thyroid boosting supplements is an Indian herb called Guggul.

Guggulsterones cause an uptake of iodine in the thyroid and increases the secretion of the thyroid hormones T3 and T4. Look for a preparation that contains 25mg of guggul per dose, and take it 3 times per day.

This will not make you "manly" ... just leaner.
