Hi Katherine! Thank you for taking the time to leave us a review! Qualia Senolytic should be thought of as a product that pays healthy aging dividends over time and with repeated cycles of use. In the pilot study we did of Qualia Senolytic prior to bringing it to market, most of the participants reported greater ease in comfortably performing activities and less of the occasional stiffness that can accompany aging after two dosing cycles of Qualia Senolytic (i.e., after taking a full dose of Qualia Senolytic for 2 days, taking a few weeks off, and then taking another full dose of Qualia Senolytic for 2 days). While this is one use case, we created Qualia Senolytic to support healthy aging in many areas (brain, muscles, immune function, joint, skin, etc.) so benefits may show up at varying speeds and in a variety of areas of function in different people depending on where aging is taking a toll. With that said, if you're not completely satisfied, please reach out to our team at [email protected] and we would be happy to assist you further!
