I got the blue razz watermelon Karbolyn and it definitely delivers on performance. It gives me a solid boost of energy during my workouts and helps me push through longer training sessions without feeling drained. The flavor is strong and honestly a little too sweet for my taste, especially if I’m drinking it early in the morning or during a long workout. I usually dilute it with extra water and that helps a lot. Overall, it works great and I’ll keep using it for the energy and endurance benefits, just wish the flavor was a bit lighter.
