Are my ears burning? Man, this stuff is the absolute bomb! The flavors are solid but the effect is what I bought it for.
I recommend it for anybody looking for a pre-workout with an edge.*

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.*
