Pretty average. Relatively weak compared to some other more intense formulas, this is a good place to start if you're new to preworkout. Has everything you'd want in a preworkout with a relatively smaller dose of caffeine. Taste is acceptable.

Thanks for your feedback!

I tried "USN B4 bomb" before and I found that the "Optimum Nutrition Pre-workout" has a much better taste (at least i do not need to hold my breath when drinking, i just feel like drinking a weird juice). Although the "ptimum Nutrition Pre-workout" has less caffeine compared to the "USN B4 bomb" it does make me more concentrate on my workout like what the "USN B4 bomb" works on me. However, i sweat more when using the "USN B4 bomb". I think i would go back to prrchase "USN B4 bomb after i finish this bottle.

Thanks for your feedback!

Great pre-workout. The taste is probably my favorite.
