HOW IT WORKS
Three Steps. That's It.
Mix
Add one scoop (5g) to any drink: water, protein shake, coffee, your pre-workout. It disappears completely.
Saturate
Creatine saturates your muscles over 3–4 weeks at 5g/day. No loading phase required. Just consistency.
Get Stronger
More power. More reps. Faster recovery between sets and between workouts. Compounding gains, month after month.
WHY IT WORKS
Strength That Compounds
Creatine replenishes ATP, the energy your muscles burn during explosive effort. More ATP available means more reps, heavier weight, and faster recovery between sets.
The research is overwhelming: hundreds of peer-reviewed studies confirm 5–10% strength gains within the first month of consistent use at 5g/day.
THE PART NOBODY TALKS ABOUT
Your Brain On Creatine
Emerging research suggests creatine supports cognitive function under sleep deprivation and mental fatigue. The brain uses ATP just like muscles do, and creatine helps regenerate it.
If you work shiftwork, parent through sleep deprivation, or just need to think clearly after a brutal night, this matters.
DESIGNED FOR YOUR LIFE
Invisible By Design
Unflavored means it disappears into anything: your KtP pre-workout, your protein shake, your morning coffee, plain water. Zero taste interference. Zero extra sweeteners.
One ingredient. One job. One scoop per day. That’s it.

Frequently Asked Questions
WHY I BUILT THIS
From the Firehouse to Your Kit
I’ve been in the fire service for close to two decades. I’ve forced doors, humped hose up stairwells, and worked 24-hour shifts on 3 hours of sleep more times than I can count.
I built Keep the Promise because I watched too many good firefighters fall apart because the right systems didn’t exist. I started with training programs. Then I built the supplements I wish existed when I started.
Every product in this line is something I personally use. If I wouldn’t put it in my own body, I won’t put my name on it. That’s the promise.
— TJ, Founder of Keep the Promise
