The face behind GRIND-RX
GRIND-RX is not a project by marketers or investors, but by athletes who are themselves in the middle of the box. From our own training and experiences with CrossFit and Hyrox, one thing became increasingly clear: the supplement market primarily revolves around standard fitness, not the hybrid athlete.
I am Marco Bosklopper – founder of GRIND-RX, CrossFitter, Hyrox athlete, and father of two. I know how important nutrition and recovery are to get the most out of your performance. Out of frustration with standard fitness supplements, I decided to do it myself: create supplements that I myself use every day — transparent, effective, and without unnecessary additives.
We believe: if it works for us, it will work for you too.
The drive behind GRIND-RX
GRIND-RX was born out of frustration. Too many supplements full of empty promises, under-dosed blends, and ingredients that only look good on a label. We wanted something different: products that actually work for the hybrid athlete.
Why? Because the market is flooded with standard fitness supplements, but offers little for athletes who demand more. Think CrossFit, Hyrox, and functional training—sports that combine strength, endurance, and focus.
