Hi, I’m Brian—a Registered Nurse and Army National Guard member. For 20 months, from September 2023 to April 2025, I battled crippling low energy and disabling brain fog from long COVID. My active life came to a halt, and my home felt like an assisted living facility, with my wife and kids taking care of almost everything around me. 

I went to dozens of doctors, read dozens of research papers, tried dozens of medications, dozens of supplements and tests, without any improvement. We did discover that I had mitochondrial problems through blood tests and looking at a piece of my muscle cut out of my calf by a neurosurgeon and viewed under a high powered microscope.

Everything changed the last week of April 2025 when I discovered methylene blue. With Methylene Blue, I regained my energy, mental clarity, and joy. By May 2025, I was back in action, running, jumping and swimming.
