I cannot recommend Dr. Ethan highly enough! He has literally written the book on peptides, and his expertise shines through in every aspect of his care. After struggling with rheumatoid arthritis for five years, which left me with debilitating issues walking, I was beginning to lose hope. But thanks to Dr. Ethan’s treatment, just three months later, my feet are mobile again and my wrists are about 70% better. This truly feels like a miracle. My mood has perked up and I feel incredible.

Dr. Ethan is not only a genius in his field, but he also genuinely cares about his patients. It’s clear he’s motivated by a passion for healing rather than money. His dedication and knowledge have changed my life for the better, and I am incredibly grateful to him for giving me back my mobility and independence.

I’ve been working with The Catalyst Clinic for almost a year now, and I felt compelled to share my story. When I first came in, I was struggling with rheumatoid arthritis and a constant loss of energy. Honestly, I was skeptical and thought all of this was just “hocus pocus.” But I can honestly say—this stuff works! After almost a year, my blood levels are now stabilized, and what used to be chronic, daily pain has been reduced to just minor discomfort. Even more amazing, my hormone and immune system levels are finally normal—something I haven’t experienced in over ten years! I’ll never forget one of my first visits: I broke down in tears out of sheer frustration, and Dr. Ethan reassured me that he would do everything he could to help. He truly meant it. I probably shouldn’t mention this, but when money was tight, Dr. Ethan went out of his way to give me a significant discount so I could continue my therapy. That kind of compassion is rare. I am extremely grateful to Dr. Ethan and the entire team at The Catalyst Clinic. They’ve given me a quality of life I didn’t think was possible anymore. Words can’t describe how thankful I am for everything they’ve done for me. If you’re on the fence or feeling hopeless, I highly recommend giving them a chance. They changed my life! Show less »
