Frog Fuel | Established MMXII
Pre-Workout Evolved for Reps, Miles, and Brick Sessions
Caffeine-free. Ready to drink. Built for every way you train.
Go Harder With Ultra
The Event Is One Day. The Work Isn’t.
If you’re stacking miles, intervals, climbs, bricks, and lifts, you can’t gamble with your fuel.
Ultra Pre-Workout Evolved gives you fast, clean performance support in one ready-to-rip shot — with carbohydrates and electrolytes for training fuel, plus beta-alanine, citrulline malate, and Nano Hydrolyzed Collagen® Protein in one ready-to-rip shot.
Developed by Navy SEALs who needed performance fuel that could keep up with combat training. Trusted by endurance athletes chasing new PRs.
BUILT FOR THE SESSIONS BETWEEN START LINES
A short-lived stim hit isn’t ideal for multi-hour sessions. If your training takes everything out of you, a quick burst of energy will only leave you hanging when the work gets heavy.
Caffeinated, junky ingredients throw you off your game. When your mind and body feel like they’re buzzing out of control, focusing on the work feels next to impossible.
Ultra Pre-Workout Evolved supports the effort window with clean, steady energy for sharp, focused performance that holds through runs, rides, swims, lifts, and more.
Recover Daily. Train Hard. Repeat.
Power Protein’s 15g Nano Hydrolyzed Collagen® is shown to digests fast to support joint and muscle recovery.
Made For Multi-Sport Work
Tempo runs to long rides, bricks, pool work, and strength days — Ultra gives you one clean fuel format for the many ways you train.
Fits Your Training Week
One ounce, ready to drink, shelf-stable. No shaker, no prep, no break in your routine.
Fuels Recovery While You Work
Ultra supports the joints, muscles, and connective tissue that take the hit from long runs, heavy lifts, and interval training.
Power Every Way You Train
Developed by Navy SEALs
Originally developed for Navy SEAL training environments, Frog Fuel was built for people whose bodies have to show up again tomorrow.
Ultra Pre-Workout Evolved brings that same standard to your training with clean, fast fuel that fits before or during demanding sessions, with Nano Hydrolyzed Collagen® Protein in a portable 1.2oz shot.

Most Pre-Workouts Calls For A Tub and Shaker.
NOT ULTRA.
Endurance training is hard enough. It’s even harder with pre-workout that hits too loud, makes your skin crawl, or feels like it belongs in a max-effort lift.
Some days you’re running long. Others you’re riding, swimming, lifting, or stacking a brick session on legs that already logged miles. Your training doesn’t stay in one lane, and your fuel shouldn’t either.
Rip It. Feel It. Go.
Ultra Pre-Workout Evolved gives endurance athletes a cleaner way to fuel the session—without the heavy stim hit, shaker-bottle routine, or weird full-body buzz that can throw off your performance. It’s portable pre-workout built for every way you train: long efforts, mixed-discipline days, and sessions where you need to feel ready, not overloaded.

Great product
I can definitely tell the difference when I run out of it. The first week of using it after my aerobic workout was amazing, it help me recover faster than normal in preparation for my weightlifting session. This product is a good must-have if you’re doing two a days for training or when doing cardio first than weight training later.

So convenient and easy to take. The taste is fine (Better than anything I have every tasted like this) and great ingredients for such a small serving. Now a part of my daily intake right after workout. Awesome product!

My favorite protein
It’s easy to digest, absorbs fast, and doesn’t require any mixing. The convenient packets make it perfect on the go. If you want a clean, efficient protein that actually delivers results, Power Protein is worth trying.

It’s a game changer no doubt
Just spent 8 days straight in the wilderness in NH with 60lb ruck. The day to day recovery was noticed with the use of Frog Fuel. 70 miles completed in some of the roughest terrain in the northeast. Clean, easy to use and effective. I won’t take on longer distance hikes without your product.

I’ve been using Power Protein for several weeks now and I’m not nearly as sore the day after going to the gym and also training martial arts 3-4 times a week!

What’s in Frog Fuel Ultra Pre-Workout Evolved?
While some pre-workout gels and liquid pre-workouts contain controversial ingredients, Frog Fuel pre-workout without caffeine is made from simple ingredients. The collagen protein in Frog Fuel is reduced to 1% of its original size, making it easy to digest.

When should you drink Ultra Pre-Workout Evolved?
Take one packet 15 minutes before and every 45-90 minutes of activity depending on the level of exertion.
How fast does Frog Fuel’s Nano Hydrolyzed Collagen® digest?
Fast. An in vitro digestibility study by Kennesaw State University showed no remaining proteins at the 15-minute mark, compared to 70% remaining of a leading whey isolate.
What does it taste like?
A tart berry flavor. Some people love the taste, some don't. What's consistent across 24,000+ 5-star reviews: people keep taking it because of how it makes them feel, and the positive results they get, regardless of how they feel about the flavor.
Do I need a shaker or blender?
No. Frog Fuel comes in a ready-to-drink 1oz pouch. Rip it open, sip it, done.
Does this replace my whey protein?
No. Frog Fuel is a complement to whey, not a replacement. It's built to support joints, tendons, and connective tissue in addition to muscle, so it pairs with whey rather than competing with it.
Is this backed by real research?
Yes. Frog Fuel's Nano Hydrolyzed Collagen® formula was developed by a Stanford biochemist and has been clinically tested. It's also used in over 4,000 healthcare facilities. Full study list here.
Who is Frog Fuel actually built for?
Everyday athletes make up most of who's actually using Frog Fuel.
