Testing and Supplements

Our goal is to help you achieve healthy human longevity. This can be done with the assistance of testing — which can give insight into what’s happening within your body so you can improve your health and lifespan — as well as supplements, which fight low energy, aging, body composition changes, depression, loss of libido, and much more. 

Look Great, Feel Great

Many of our patients first visit us feeling tired, defeated, and ready to make a change. After treatment, we are happy to see our patients transformed, confident, and ready for their next journey. Beauty Within offers much more than med spa services. We are a science-backed wellness and anti-aging center that is offering an entirely enhanced lifestyle. We incorporate Dr. Gretzula’s clinical experience with stress management, medication, nutrition, and diagnostic testing to get you looking and feeling your absolute best.


By understanding your body, you can create a treatment plan for how to feel your best and live life to the fullest. Our lab testing can provide insight into how your lifestyle affects your health; predict which chronic diseases you are susceptible to; give you a comprehensive knowledge of how your body functions, and can offer a clearer picture of your overall health and wellbeing.
