DF-18 — Make the Turn, Finish Strong
Steady Through All 18.
Not Just the Front Nine.
DF-18 is a caffeine-free, sugar-free pre-round drink mix — 25 ingredients, every dose on the label — built to support hydration, calm focus, and energy for the 4–6 hours a round actually takes.
Trusted on the lesson tee.
"Across the board it helps my players finish strong, especially on the last 5 holes."
— Stan Sayers · 2024 Colorado Teacher of the Year"It's my secret weapon and I now recommend it to all my students."
— Dave Bisbee · CEO, Back On Course Golf"I feel more 'in tune' and have been using it for rounds or long days of lessons. I can't imagine playing without it."
— Brian Jacobs, PGA · Director of Instruction, BallenIslesGolf is an endurance sport. Almost nobody fuels it like one.
A round takes four to six hours. Most golfers walk to the 10th tee running on a gas-station coffee and whatever the beverage cart is selling — then wonder why grip pressure, tempo, and decision-making slip on the holes that decide the score.
It isn't your swing failing. It's hydration, focus, and energy running down — three things you can actually do something about before you tee off.
Four systems. One stick. Every dose on the label.
Hydration Retention
Retention beats volume. DF-18's hydration matrix supports fluid retention so your body holds and uses the water you drink — deep into the back nine.
700mg potassium · full electrolyte panelCirculation
Supports blood flow and oxygen delivery through nitric-oxide pathways — the quiet work behind maintaining tempo and power on long walks and hot afternoons.
Nitric-oxide precursor blend, fully disclosedCalm Focus
Supports steady mental clarity without caffeine's spike-and-crash. Not a jolt of alertness — consistent decision-making from the first tee to the last putt.
0mg caffeine · 0g sugarRecovery
Supports your body's recovery processes so the round you played Saturday doesn't decide how you feel Sunday.
Recovery actives, transparently dosedThe same golfer. A different back nine.

Before you tee off.
Does DF-18 have caffeine?
No — DF-18 is caffeine-free. It supports steady focus and energy without the spike-and-crash cycle, and there's no caffeine to interfere with winding down after a late round.
What does it taste like?
Bold, not too sweet. Both flavors were rebuilt in February 2026 (same formula, new taste). It's built to be drunk on a golf course over 18 holes, not to taste like candy.
When should I drink it?
Mix one stick with 12–16oz of water and drink it shortly before your round. It's designed to support hydration, focus, and energy across the 4–6 hours a round takes.
How is this different from an energy drink?
Energy drinks lean on caffeine and sugar for a fast spike. DF-18 has neither — it's 25 transparently-dosed ingredients supporting hydration retention, circulation, calm focus, and recovery over a full round.
What exactly is in it?
All 25 ingredients with their exact doses are printed on the label — no proprietary blends. See the full ingredient panel on the product page.
