Best pre-workout I’ve ever had. I’ve tried transparent labs in the past and was disappointed with their peach mango, but they must have re-formulated their flavors because 10/10. Raspberry hibiscus is my favorite!!! Watermelon peach is also 10/10!!

The taste impressed me the most. I chose the Blue Raspberry flavor — absolutely perfect! Until now, I hadn’t found a product that doesn’t feel heavy on my stomach while I’m training. As for the stimulant-free version, I don’t really notice any effects yet, but we’ll see how it performs after using it for a bit longer. 🙂
