one of the best
Review by Gym Freak (24 October 2017)
gives me the extra kick no crash like other pre work outs
Very nice!
Review by Terry (16 September 2014)
Nice smooth energy without any crash and tastes great. Seemed to really help me on my bike rides, before and during the ride. A little pricey but I reckon it's worth it.
Good stuff
Review by scott (15 January 2014)
average taste, can be taken whenever you need it and gives you good energy for a workout
Need to overdose
Review by Shaun (22 October 2013)
The taste of this is awesome. BUT due to it not being that strong maybe go one extra scoop. Then it works nicely. No crashing at all. I am caffeine sensitive and needed to "overdose" - nice product overall
Good sustained energy release
Review by Jean-Pierre (26 April 2013)
The most effective pre-workout I have used so far. Great energy during my workouts. Helps me through my day. This also does not give me funny pins and needle like other pre-workouts. Blueberry taste like strong(Concentrated) Energade. Would like to try the grape.
Must Have
Review by Cuddles (11 March 2013)
Struggled with the long grind during the day at work and gyming but taking this either before or after really helped me feel great.. definitely an awesome product.
Review by Mike (11 February 2013)
Best Pre-workout and daily lift ever! No drop. Could live off this stuff!!!! Must be the best tasting supplement on the market. Grape is unbelievable!
Blue raspberry is the best
Review by Lauren (29 January 2013)
Another quality product from ON. Blue raspberry tastes great! No side effects of fatigue when it wears out. I had a great amount of energy and focus for my workouts - even intense cardio sessions.
Great energy, no crash
Review by Edwin (29 August 2012)
I do am workouts and the buzz this gives me is amazing.
Also great as a boost mid-afternoon before second training session.
Great taste (Blue Raspberry the better of the two) and most importantly NO CRASH or stomach upset.
Sustained Energy
Review by Mark  (22 May 2012)
Great pre-workout, sustained energy with no crashes. Blue rasberry tastes real good.

Review by Ian (17 May 2012)
I used it through out the day as I was training in the morning and had hard physical days at work and this really help me get through the days full of energy. And with no jitters like Jack 3d gives

Review by storm (31 January 2012)
most effective amino shake on the market
Instant Energy Boost
Review by Koles (7 October 2011)
This is the best pre-workout product I have used. The energy I have during my workouts has increased. No jitters either, and I've never had to use anything other than the minimal dose. Used the Concord Grape flavor, wasn't a big fan of the taste, tastes alot like Kool-Aid. I've heard the other flavours are better tasting though. Great product overall.
