Pure power
Review by Iron_Man (18 August 2021)
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.
Review by Beginner (16 April 2021)
this product works! but the price is crazy, ON come on now.
Great Value
Review by Jean-Pierre (6 March 2020)
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
Review by Jaco (13 April 2018)
Although price is a bit high, you get what you pay for . Your energy doesn’t drop immediately like with most other preworkouts .
Great Pre.. Tried it and I'm loving it
Review by Daddy J (23 July 2017)
The taste is awesome and no hectic tingling. I'll definitely recommend it to most people wanting a clear focus and it last a bit longer in the system
Review by King (1 May 2017)

Gold standard pre work out
Review by Lee (8 December 2016)
Too much money for nothing.....useless product.......
Very Good Quality
Review by Renzo  (4 July 2016)
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
Review by fitnezz (7 April 2016)
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
Review by Ameer (23 March 2016)
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.
good stuff
Review by Faheem (18 January 2016)
by far the best
Review by Luke (21 November 2015)
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.
Awesome Product
Review by Justin (12 August 2015)
Awesome pre workout!
It tastes great and gives a smooth and continuous amount of energy throughout a workout.
No crash
Great pumps
Great Taste
Review by jemay (3 August 2015)
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
Review by Brian (28 July 2015)
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.
