I just bought this product yesterday and tried it immediately. I absolutley love it. C4 Cellucor has always been my favorite pre-workout, and I was super excited to hear they were coming out with one that had a thermogenic in it. I was a little skeptical at first about the cherry limeade flavor because I've tried that flavor in a different brand of pre-workout and i was not impressed. Luckily, the C4 cherry limeade was very smooth and did not have a sour after taste. I am excited to see the "RIPPED" results, but as of right now it is my new favorite, i had a great workout, with a good sweat. I would definitely recommend this product, if you are a fan of the other C4 products.
