Maximizes Strength and Power

Carbohydrates create a source of fuel for your muscles to feed on during high-intensity workouts. Without these nutrients, your body cannibalizes existing muscles to create fuel, stunting your goals and growth. Karbolyn supplies your body with the complex carbohydrates it needs to fuel your muscles and help you achieve your goals.

Fueling my harder days

I was crashing during my workouts, particularly on leg days, so this was recommended to me by both a friend and my coach. Feeling better and helps with a better pump as well. I like fruit punch, however my friend says Blue Razz is great too (that one tastes similar to cotton candy).

No need to go back to vitargo or glycofuse

Beyond happy with the pumps from these carbs. Much better than anything else I see on the shelf at Popeyes. Comparable to vitargo at a fraction of the cost.

Karbolyn for the win!

Best product I’ve ever consumed. I’ve recommended it to several people and have since purchased the larger container since. The increased glycogen stores without the ‘spike and crash’ is essentially instant carb loading and before during or after a workout allows for an all day full great feeling. Blue rasp watermelon is delicious and mixed well 10/10 Dr Jeff golini (creator) has a pod cast by efx sports that’s very informative if anyone wants more info on inportant fitness topics
