Endo-Test is the first testosterone hormone rebalancing serum of its kind. Specially formulated by the AQ Skin Solutions founder, Dr. Al-Qahtani, a professor, scientist and immunologist, Endo-Test works by activating the proteins in the body which are responsible for producing the testosterone hormone. While testosterone is commonly associated with men, a woman’s need for testosterone is of equal importance. As we age, the proteins which produce this hormone gradually switch off leading to depleted levels. This can have a significant impact on both the health and well-being of men and women.
