Harry Schwezler –
I recently tried Optimum Nutrition Amino Energy in Blue Raspberry flavor, and I’ve gotta say, it’s a game-changer for my pre-workout routine. This energy powder gives me a solid boost without the jitters or crash you get from some others.
Let me tell you, the taste is pretty good. The Blue Raspberry flavor is super refreshing and tasty, making it a breeze to drink before hitting the gym or starting my workout. It’s not too sweet or fake-tasting, which I really like.
