Pure power
Rated on performance - 5 stars.
Rated on price - 2 Stars.
It is a very good quality product and gives you good clean energy that keeps on going. The stims are not crazy so you may not get that tingly feeling from this. the strength boosters is not gona give you an instant 1000% increase but it will help you make progressive gains in size & strength in conjunction with the other components.

Great Value
Very effective pre-workout even though the price is quite high, really improves workout intensity as well as giving a strength boost for training sessions. Reasonable caffeine content means it does not make you feel like you are about to have a heart attack like some other pre-workouts and you don't crash so heavily once it starts to wear off, highly recommend.

All round quality
Although price is a bit high, you get what you pay for . Your energy doesn’t drop immediately like with most other preworkouts .

Very Good Quality
Optimum always do what they say. Again they've done it. Very nice pre. Makes for a nice change when I need something without creatine. Fruit punch flavor is lovely.

Not expensive for ON
For the price you pay and what you are getting this is a winner. I love ON, but their whey protein has become crazy expensive. This product does what it says and I know there is no funny stuff inside.

Good Healthy PreWorkout Supplement
This is a a great-tasting pre-workout with most of the nutrients which have been proven to be beneficial. Ordered the fruit punch flavour and it was very tasty and gave me nice clean energy and focus, with no overpowering rush or come-down, so sleeping is a breeze,
You could take this around 4 hours before bedtime and sleep fine. Great for those sensitive to caffeine.

Note that this does not have vasodilators, or an intense creatine complex, so strictly speaking, this isn't the best for insane weightlifting. If you're looking for an all-round sustainable increase in strength, focus and a bit of stamina, without the side-effects, this is for you.

Be sure to shake the container before use, as it seems bigger granules separate from smaller ones, which might affect how it hits you.

Fantastic
This is by far the best pre-workout i have used in years. Incredible prolonged energy and mental focus. Great vascular dilator.
I would recommend this to anyone, Whether you are a seasoned athlete or just starting out.
Start out with half a scoop and increase the dosage as you get used to the stimulants.
Great for any tested athletes as well, i have used this and passed drug tests.

Review by jemay (3 August 2015)
Great Taste
I have tried so many preworkouts that it takes a lot for one to stand out for me. I really like this one because it actually has enough beta-alanine in it that I can feel it without adding any additional and the flavors are awesome. Pineapple is subtly sweet but tart, which I love, and the fruit punch actually has some body to it. Instead of a weird "red flavor" the fruit punch actually tastes like fruit, I swear I can taste the pineapple in it. i got a lean muscle and good shape.

Quality product from a quality brand
No jokes, ON is one expensive brand. But you get what you pay for especially their Whey. Their new preworkout rocks. The price is very affordable for ON and the product works great.
Not crazy 'didn't sleep for 4 days' kind of stuff, just nice and smooth.
