Dr. Hugh McTavish is a scientist, innovator, and problem-solver—driven by personal experience to create solutions that work. A Ph.D. biochemist, he founded Square-Immune after developing a treatment for his own frequent cold sores. When it worked for him, he knew it could help others, so he started SquareX Pharmaceutical Corporation to bring the solution to more people. Squarex has since conducted three clinical trials on SADBE™, the active ingredient in Square-Immune—and it was effective in all three clinical trials!
