Orange dreamsicle was not my first choice but I like it. Great for that boost for a killer workout.

I have always used c4 I have tried other preworkouts and they don't compare. Not only does it taste good but it really gives you that pump and extra push to do more.

It was very clumpy and seemed like moisture had gotten in it. If it wasn't for a final sale I would've returned it immediately. Last time I ever order workout products from groupon.

The orange flavor reminds me of medicine. Love the other flavors of pineapple and green apple.

I just didn't care for the flavor. Taste more like baby aspirin and not dreamsicle. The supplement worked very well, but I'm just not a fan of the taste. Pity, I love dreamsicle anything and was looking forward to it.

It gives me a good boost prior to my work out without any jittery feeling. The taste is excellent in my opinion.
