The primary function of EstroQuench™ is designed to quench excessive production of estrogens and aberrant functions of them while supporting optimal function of androgens by maintaining the health of androgen producing glands. 

The ingredients inside EstroQuench™ is documented to have anti-aromatase activity as well as androgenic adaptogens which support the function of endogenous aromatase inhibitors. Collectively these herbs promote minimal production and function of estrogens, while promoting testosterone function, including optimal sexual function in both genders.
This Hormone Specific Formulation™ is provided by Douglas Laboratories® and formulated by Dr. Joseph J Collin. It is created to support the optimal function of specific hormones through the use of hormone specific adaptogens, hormone specific agonists and hormone specific functional mimetics.

How is EstroQuench™ used?

EstroQuench™ is used by healthcare professionals to reduce estrogens levels by inhibiting aromatase activity, which will decrease the conversion of androgens (testosterone and androstenedione) to estrogens (estradiol and estrone).
EstroQuench™ is used to decrease estrogen dominance while maintaining the levels of testosterone and other androgens. EstroQuench™ improves patients with many conditions including:

Women who want lower estrogen levels, to decrease breast cancer risks or with breast cancer therapy.
Men who want lower estrogen levels to, decrease prostate cancer risks or with prostate cancer therapy.
Women who want to overcome estrogen dominance, and improve their Progesterone to Estradiol Ratio.
Men who want to overcome estrogen dominance, and improve their Testosterone to Estrogen Ratio. Men who are infertile with a low serum testosterone-to-estradiol ratio can be treated with an aromatase inhibitor [11792932].
Patients who are on Testosterone Replacement Therapy (TRT) and want to decrease the conversion of testosterone to estradiol.
Men on TRT who want to prevent the development of gynecomastia or prostate disorders.
Male athletes who want to maintain proper Testosterone to Estrogen Ratio.
