Formulated by Dr. Joseph J. Collins, an experienced healthcare practitioner who has been directly involved in advancing the practice of supporting natural hormone health since 1993. TestoQuench® for Men is a Hormone Specific Formulation™ of herbal ingredients designed to help support prostate health and associated urological symptoms by moderating androgen activity. Saw palmetto has been demonstrated to moderate 5-alpha-reductase, an enzyme that converts testosterone to the more androgenic dihydrotestosterone, and may support the function of the urethra. It is used in Herbal Medicine to help relieve the urologic symptoms (e.g., weak urine flow, incomplete voiding, frequent daytime and nighttime urination) associated with mild to moderate benign prostatic hyperplasia. This formula also includes a patented extract of piperine (black pepper fruit), plus important extracts from hou po, stinging nettle, holy basil and pygeum.
