Hi Robert, what you feel from taking Qualia Senolytic can vary person-to-person: for some people it may be the skin, for other people it may be fat or muscle tissue, for others it could be the brain, joints, immune system, etc. Because of this, there is no one way that Qualia Senolytic is experienced. With the above in mind, the areas you should expect benefits are the areas that are typically most impacted during aging, so pay attention to signs of healthier skin, muscles, joints and brain functions, as well as overall health and energy, after two-to-three months of taking Qualia Senolytic.
