THE STORY BEHIND SLICZ.
It all started on the final day of the 26th “Mayfield 12” golf tour, when Bob Dyer, a seasoned golfer, and Ian Dempsey, a former professional triathlete and new to golf, struck up a conversation. Ian was shocked by how drained he felt after just a few holes. “How is golf more exhausting than a marathon?” he asked. That moment sparked an idea: what if golfers had access to the same kind of targeted, high-performance nutrition athletes use in endurance sports?
Using his background in elite training, Ian began testing adapted endurance supplements on the course - and the results were immediate. With clean energy, sharper focus, and better consistency, both he and Bob knew they were onto something. That’s how SLICZ was born.
FROM EXPERIENCE TO INNOVATION.
We used Ian’s deep knowledge of endurance nutrition, along with published research, expert consultations, and input from Loughborough University’s Peak Performance team, to build a formula specifically for the demands of golf. This wasn’t about generic supplements - it was about creating clean, effective, and precisely timed products to support focus and energy throughout all 18 holes.
Once we had our formulas, we tested them ourselves and with a group of 20 golfers - weekend players, low handicappers, and everything in between. Their feedback helped us fine tune every aspect, from taste to performance. When they reported feeling stronger and more consistent on the course, we knew we had something special.
PRECISION, QUALITY & THE 18 MONTH JOURNEY.
Bringing SLICZ to life at scale took time. We spent 18 months finding the right manufacturers, building in strict quality control, and making sure every product met the standards we set from day one. We refused to compromise - and that’s why you can trust what’s in every box of SLICZ.
FOR EVERY GOLFER, EVERY LEVEL.
SLICZ is designed for all golfers - whether you're a novice learning the ropes or a pro chasing birdies. Golf demands energy, focus, and endurance, no matter your skill level. Our three-stage system supports you throughout your round with clean, effective ingredients that just work.
WHATS NEXT?
Now, we're excited to relaunch SLICZ and bring it to even more golfers. But this is just the beginning. We’re committed to listening, learning, and continuing to innovate - so we can keep helping you feel and play your best.
