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
