About Us
Our Story...
We’re Mark Gijsen (48) and Robert Peeters (52) – the team behind 24PEPTIDES and the creators of Grail Formula.
Both of us are fathers of two, and that makes one thing crystal clear: health isn’t just about ourselves, it’s about our families too. Every choice we make is driven by the belief that staying strong and healthy today builds a better tomorrow for the people we love most.
What connects us? A lifetime of entrepreneurship, a passion for high-intensity sports, and the mindset to keep pushing forward even when life throws challenges our way. From martial arts to motocross, we’ve both learned what it means to test limits, recover, and rise again.
Over the years, those challenges made one thing clear: standard options for recovery and performance often weren’t enough. Surgeries, rehab, and traditional approaches had their place, but results were inconsistent. That frustration pushed us deeper—into research, into alternatives, and ultimately into peptides.
Why We Started 24peptides
Our journey led us to research peptides—a field with incredible potential for performance, recovery, and vitality. The more we explored, the more convinced we became that this was the way forward.
But we quickly realized something: not all peptides were equal. Transparency was missing, COAs were inconsistent, and quality wasn’t guaranteed.
That’s why we founded 24PEPTIDES: a company built on trust, purity, and transparency—values we demand for ourselves and our families.
Why Grail Formula
Instead of relying on outside labels, we launched our own brand: Grail Formula.
For us, it’s simple—lasting results require purity, consistency, and quality without shortcuts. Step by step, we’re expanding independent testing and Certificates of Analysis to give researchers full confidence in what they’re working with.
What We Stand For
Trusted quality and transparency
Personal dedication & experience
Research peptides only – no shortcuts
Honest, reliable service
At 24PEPTIDES, our philosophy is clear: we don’t follow the standard—we set it. That mindset drives us in sports, in business, and in building Grail Formula.
