There are many hormones which work with growth hormone and can help it work more effectively in the body. They are Estrogen, Progesterone, Melatonin, DHEA, and Thyroid Hormone.

Estrogen: Slows the loss of minerals from bones and increases blood clotting, however, it decreases oxygen metabolism to the cells and is known to be a factor in breast and uterine cancer.

Progesterone: Essential for the metabolism of glucose and the proper formation of bones, progesterone stimulates the production of new heart cells in the body and supresses cancer growth.

Melatonin: Produced naturally in the brain by the pineal gland, it stimulates the production of growth hormone and reduces free-radical damage. Melatonin has the ability to stabilize the body's biological rhythms and stimulate the immune system.

DHEA: One of the most powerful hormones for improving brain function, DHEA (dehydroepiandrosterone) is the most abundant hormone found in the bloodstream. The function of DHEA is to serve as a precursor for all other hormones in the body by supplying the body with what it needs to maintain an optimum balance of all hormones that regulate metabolic functions. As we age, the level of DHEA declines dramatically. Low levels of DHEA are linked to such conditions as diabetes, obesity, high cholesterol, heart disease, arthritis, and many other symptoms associated with aging.
