I tried this once about a year ago and it was decent but just bought some recently and it's not good. The taste and the way it dissolves is fine but minimal energy, no itching (I typically enjoy with a good pre), finding myself with no focus and overall not motivated. I've had a tough time finding something without DMAA that is good and this adds to the list of mediocre pres. *

Preworkout was dried out and hard. I had to take a knife to break it up in chunks. *

The pumps on this are the some of the stronger pumps a guy can get from a pre. I’ve tried many varieties and brands and this one holds true- the extra price is worth it- esp on a bogo... the sour gummy flavor is pretty decent but can have a chemical-type taste... it’s still good though *

I like this preworkout. It has a good amount of Citrulline and Beta Alanine. Definitely gets me through me workouts. The Creatine is a plus. *

Flavor is NOT sour. Its pretty sweet and tasted very good. Pump and energy are great too. I typically do NOT buy c4 products but gave this a try based on the label, and price. It stacks up with other higher end pre workouts.*
