I am training pretty aggressively 2 times a day and mixing Crossfit and Bodybuilding during the week. This helps me maintain muscle levels while burning so much energy. Definitely a good part of the supplements I take.*

The flavor is an immediate hit once you take a sip. The mixability is also great, it mixes easily in water and there are no clumps. Regarding energy...WOW! This formula makes you blast through your workout with zero fatigue, and definitely more left in the tank.*

Gaspari makes excellent products. I dilute this times 4 and use it for during running long distances. The bottle that was free that came with this smelled so toxic and not right and it made the protein shake taste bitter after I washed it.*
