Key ingredients

Karbolyn®
A patented carb that refills glycogen fast, without the crash or gut bloat you get from simple sugars.*

Sustalyn®
Boosts glycogen production and pulls more water and electrolytes into your gut, so hydration and fuel absorb together instead of fighting each other.*

AminoZorbâ„¢
Supports muscle protein synthesis and helps limit breakdown over long efforts, so recovery starts before you're even done.*

Electrolyte blend
Replaces what you sweat out, so cramping and fade don't end your effort early.*

How to use

Mix 1 scoop in about 16oz of water before, during, or after your effort. Adjust up to 3 scoops (120g carbs) based on sweat rate, intensity, and taste. For training or events: drink 30 minutes before, sip through, drink after.*

FAQ

Epic Fuel FAQ.

Can't find what you're looking for? Contact us and a team member will get back to you.

Will Epic Fuel upset my stomach?

That's exactly what it's built to avoid. Karbolyn® absorbs like a simple sugar without the crash, and Sustalyn® pulls more water and electrolytes into your gut instead of leaving them to sit. No bloat, no cramping, no mid-race regret.*

How much water do I mix it with, and can I adjust it?

Start with 1 scoop in 16oz of water. If the effort runs long or your sweat rate is high, scale up to 3 scoops (120g carbs). Dial it to your race, not the other way around.*

Can I use Epic Fuel with Coffee Booster or Creatine?

Yes. They're built to work together, not compete. Coffee Booster covers the start, Fuel covers the middle, Creatine covers daily recovery. Stack what your day actually needs.*

How is this different from a normal sports drink?

Most sports drinks are sugar water with salt. Epic Fuel uses Karbolyn®, a patented carb that fuels like a complex carb but absorbs like a simple one, so you get steady energy instead of a spike and a crash.*

Distance Runner - Great Hydration and Fuel

I am a distance runner, and this product has simplified priming myself for a run with advanced hydration and fuel. The taste is pleasant but subtle so it doesn’t affect my water bottle and is easy to consume while on the move.

The tastiest!

This quickly became of my top favorite fuel options! I have tried so many different ones over the years, but the taste of this one takes the cake! It’s a perfect blend for any distance! Double up scoops for longer runs! Mixes really easily and goes down smooth. Not chalky, bitter or too sweet. Highly recommend!!

After Action Report - Epic Fuel

Date of Use: 20250412
Duration of Activity: 120-minute endurance run
Product: Epic Fuel - Lemon Lime
Protocol: 2 scoops pre-run, 1 scoop/hour during, 1 scoop post-run
Total Carbohydrate Intake: 160g–200g

⸻

1. Taste & Mixability
• Flavor: Very mild lemon lime flavor with no lingering aftertaste. While clean and non-offensive, the flavor could benefit from a bit more intensity. After prolonged use, lemon lime tends to feel played out — alternatives like mojito, piña colada, or mango could offer a refreshing twist.
• Texture: Slightly chalky when mixed with 16oz of water, though not off-putting. That said, it wasn’t gritty or clumpy.
• Mixability: Excellent. Unlike many electrolyte powders, Epic Fuel dissolves fully and remains in solution — no need to shake continuously to avoid settling.

⸻

2. Performance & Digestibility
• Energy Response: Felt a noticeable and immediate energy boost, especially with 80g of carbs taken first thing upon waking. Sustained performance throughout the session with zero crash or drop in energy.
• Carb Strategy: 2 scoops before, 1 scoop per hour during, and 1 scoop post-run proved to be a dialed-in ratio for a 2-hour endurance effort.
• Digestibility: No issues with bloating, gas, or GI discomfort — even with higher carb intake levels. This product is gut-friendly, even under intensity.

⸻

3. Overall Impression

Epic Fuel performed exceptionally well in terms of energy delivery, mixability, and digestive ease. While the lemon lime flavor was mild and clean, there’s room for more flavor variety and depth to improve palatability for longer training cycles. Its ease of use and performance make it a solid go-to for long efforts, especially for athletes dialing in high-carb fueling strategies.

Suggested Improvements:
• Stronger flavor profile
• Expanded flavor options (mojito, piña colada, mango)

Rating: 9/10

I haven’t used it long enough to see consistency

I haven’t used it long enough to see consistency, but so far with 1.5 weeks of use one thing I’ve noticed almost immediately is that I’ve not had the typical afternoon crash at work after hard workout mornings.

DO IT.

Do it. I’ve been using this product consistently for about a month and I can definitely tell days I’ve used it and days I haven’t. Really impressed with how it fueled my body on the trails, especially now that the heat is starting to show up. I’ve used it during a race and PR’d everything. I’ve used it day to day to help me reach my nutrition goals. Definitely part of my routine now! Big fan!

Great taste!

Really like the mild flavor of this. Mixed well and didn’t leave a crazy sticky film on my teeth. Could absolutely run for days using this!
