KARBOLYN IS FOOD-BASED, FAST-ACTING FUEL. ACCEPT NO SUBSTITUTES!
Karbolyn is a clinically studied (with peer-reviewed, published research), rapidly absorbed carbohydrate supplement powder sourced from potato, rice, and corn (GMO-Free). 

It’s designed for elite athletes looking for a fast, safe, and high-performance way to quickly and easily load muscles with sustained energy and recover faster

Karbolyn enters the bloodstream like a simple sugar, yet it still provides sustained energy without "crashing". 

Karbolyn is absorbed faster than dextrose, simple sugar, bread, pasta, rice, and other carbohydrate products sold in the marketplace - simple or complex. 

Pros worldwide use it for a reason!

"Carb load" with Karbolyn in minutes, NOT hours before your event or training session!

Dr. Jeff Golini - The Bodybuilder Turned Scientist Behind The One & Only "Supercarb" Karbolyn!
Once a behemoth weighing in at an awe-inspiring 272 pounds of jaw-dropping, sleeve-splitting size, Dr. Jeff Golini, renowned in the bodybuilding community as the "8th Wonder Of The World", took the stage as a guest poser, racking up various titles.

However, after exhausting all means necessary to achieve even greater size, Jeff sought out safer alternatives. Eventually, Jeff pursued a career in science and obtained his Ph.D. 

Even though, Dr. Golini is known for inventing Kre-Alkalyn®, the world's first fully stable pH-Correct Creatine® Monohydrate, he is especially proud of Karbolyn and the impact it's had on athletes everywhere.

“I invented Karbolyn Fuel for the sole purpose of carbohydrate loading. It was designed for Elite Athletes looking for a fast, safe and high-performance way to easily load the muscle with accessible muscle energy.”Dr. Jeff Golini, EFX Sports Chief Scientific Officer

"This is premium high octane fuel for your workout. Consistent energy, no sugar crash. Lasts for over an hour of weightlifting for me."
- Luke Ciccone
"Karbolyn is one of my favorite EFX Products! When I train fasted early in the morning the carb boost from Karbolyn helps keep me full and fuel my workout without a massive crash later from caffeine or energy drinks. Sometimes I'll even mix the unflavored with a scoop of isolate protein to make a quick meal replacement shake - mixes easy and tastes great!."
