Here’s a little more about us. We created this website to reach even more people struggling with restless legs and to share our accidentally discovered ‘miracle weapon’ with them. Because behind our gel Kalter Bruder® there are actually two brothers - twins to be precise - And here, you can read our story. Enjoy! :-)



Hey there! You’ve probably read my little ‘story’ above—but what else is interesting to know about me? Well, for starters, I make music and am currently working on releasing my first album as a singer-songwriter. Like Stefan, I also enjoy sports—especially tennis—and love cooking for my family of four, usually something with lots of organic veggies. We live quite modestly in our small hometown of Salzkotten, trying to buy as few ‘new’ things as possible for the sake of the environment and our storage space. I also love dragging the family out into the great outdoors whenever I can, preferably on camping trips surrounded by nature.

Hi there! I’m Stefan, 37 years old, and I come from the beautiful town of Lüneburg. For many years, I worked in the medical technology field, advising specialists and surgeons in orthopedics, spinal surgery, and trauma surgery, before eventually transitioning to the pharmaceutical industry. This intense time, filled with countless professional discussions, training sessions, and hands-on experiences, has made the topics of sports and daily movement especially important to me. Not only is it my personal passion, but it’s also one of the key pillars of maintaining a high quality of life and treating various conditions and ailments.
