HOW IT WORKS
Three Steps. That's It.
Scoop & Shake
Add one in 8-12 oz of water or milk in a shaker bottle. Shake for ten seconds. No blender. No clumps.
Hit Your Number
19g of pure whey isolate. Fast-digesting, low-lactose, easy on the stomach. Stack two scoops for 38g.
Recover & Rebuild
Muscle protein synthesis spikes within the hour. Show up stronger tomorrow: to the workout, the shift, the day.
THE SOURCE MATTERS
Whey Isolate, Not Concentrate
Whey protein isolate is the purest, fastest-digesting form of whey available. Higher protein per gram, lower fat, lower lactose. The extra processing step is what makes the difference.
If your current protein gives you bloating or GI issues, it’s almost certainly a concentrate or a blend. Isolate processes differently and most people with dairy sensitivity tolerate it fine.
Pure isolate. No concentrate filler. No compromises on what goes in your body.
WHAT SWEETENS IT
Stevia, That’s It
No sucralose. No acesulfame potassium (ace-k). No artificial sweeteners of any kind. Sweetened with stevia extract from the stevia leaf.
Your kids can drink this. Your wellness program won’t flag it. And your stomach won’t complain about it at 10 p.m. after a long shift.
The cleanest sweetener. Period.
ONE FLAVOR. EVERY USE CASE.
Vanilla That Actually Tastes Good
Natural vanilla flavor that works in water, milk, oats, coffee, smoothies, and baking. Not candy-sweet. Not chalky. The universal base flavor that doesn’t clash with anything.
One tub, multiple uses: pre-portioned scoops in a Ziploc in your locker, a scoop stirred into your morning oats, Protein pancakes on your off day.
Vanilla doesn’t limit you. It goes with everything you already eat.

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.
