Title: Energy Boost!
Review: I do crossfit and I am an ectomorph by definition. I eat a lot and I just don't put on weight. When I workout intensely like in crossfit, I usually tend to puke or get exhausted very fast. This led to a lack of/slow muscle growth. I decided to give Gu a try after hearing about how it gives runners that endurance to for their runs. On my really heavy workout days, I take Gu right after my warmup and it kicks in about 15 minutes after that. I get to push myself further and harder and I do not leave the gym like a halfdead fish anymore. I am starting to see some gains and I really feel good after a workout. This product doesn't bulk you up and especially good for that endurance you need during an energetic workout.
