From the manufacturer


The label looks dif­fer­ent com­pared to the pre­vi­ous one I got, is it still the same OPTIMUM NUTRITION product?

As you evolve, so do we. The part of our mis­sion is to help active indi­vid­u­als bet­ter under­stand OPTIMUM NUTRITION prod­ucts. Now choos­ing the right prod­uct for you is eas­i­er with more vis­i­ble prod­uct ben­e­fits, fea­tures and flavours on each tub.


Why my tube is only 2/3 full?

Due to vac­u­um pack­ing some of the tubs may appear to be two thirds full when opened. This is nor­mal as the pow­der set­tles and does not impact on or decrease the weight or num­ber of serves list­ed on the label.


What is the best way to pre­pare my sport nutri­tion drink?

For opti­mal use, fol­low serv­ing instruc­tions on pack.

Such pow­er shall surge with­in 30 min­utes of con­sump­tion and only then will you be unstoppable.

    POISONED AND HOSPITALISEDI took this once as instruct­ed and 12 hours lat­er I start­ed throw­ing up and had oth­er stom­ach issues. It’s been 5 days and I have only just start­ed feel­ing bet­ter to be able to pick up my phone and write this review! I have been admit­ted to hos­pi­tal for dehy­dra­tion and had to be put on 3 drips. They have also con­firmed that this was some sort of poi­son­ing from some­thing I took and this was the only thing that I did have that day that was dif­fer­ent to every­one else in my house­hold. This is just the start of this com­plaint, I will be tak­ing it much further!

    That tin­gling feel­ing!Was in the mar­ket for that well missed beta ala­nine after not hav­ing a pre work­out for many many years. I remem­ber tak­ing Jack3d back in the day (pre banned Jack3d) and it was amaz­ing. I’ve chased the feel­ing of that drink ever since and noth­ings come close — until now.I drink the whole 350ml in 2 or 3 big gulps, and with­in 5 min­utes I can start to feel the tin­gling. It starts in my head and spreads to my ears. If I dou­ble the dose I feel it in my fin­gers and run­ning through my legs and out through my toes. The only way to rid this excite­ment is to chase ‘the pump’ that only an excel­lent work­out can provide.This allows me to get those extra reps which we know are the ones that count. I put the pow­der into the cup and then add water and stir with a spoon. It mix­es okay this way. Not per­fect but hon­est­ly I’m here for the effects not the taste of tex­ture. Taste is okay but a bit over­whelm­ing, espe­cial­ly if you try to take this as a shot!Ultimately, this does what it says. Great pre work­out I can def­i­nite­ly recommend.

    I’m shocked!Let me just say this and get this off my chest.. today was chest day (see what I did there) as well as my first day using this pre-work­out shake. I’ve been reli­gious­ly push­ing myself for about 8wks now in the gym and today I thor­ough­ly sur­prised myself. I was push­ing weights I couldn’t even lift off the rack. Call it place­bo, call it what­ev­er but my body is on fire! I’ve nev­er felt more will­ing to go back in to the gym!If you’re scout­ing around look­ing for a pre­work­out shake and you’re seri­ous about push­ing some iron, please please just try this out and leave a review so I know I’m not going mad here!I lit­er­al­ly have ener­gy to do some push ups before I hit the sack! I’m very pleased! Thanks guys!I would say the taste is a lit­tle over­whelm­ing with a med­i­cinic like after taste but noth­ing wild. Good stuff!!

    Amaz­ing!This is the first time I try a pre work out ener­gy and it works very well. I have been going to the gym for months and recent­ly have not felt the moti­va­tion so I decid­ed to invest in this prod­uct. I take it 30 mins before my work out and mae my way to the gym. I start my work­out as per usu­al and realise I can push myself longer and hard­er than ever before. This prod­uct is very effec­tive and I will con­tin­ue to use each time I go to the gym. I am now look­ing to get the the BCAA from the same brand.

    Increased my lifts dra­mat­i­cal­ly.Per­son­al­ly I was nev­er a fan of pre work­out because I nev­er thought I need­ed it. Take what I say which a pinch of salt, this is my anec­do­tal experience.After tak­ing a 2 year long break from work­ing out due to injury, I decid­ed to take some of this pre work­out. I pre­vi­ous­ly peaked at 200kg dead­lift with­out the aid of pre work­out sup­ple­ments and boy did they work.I fig­ured that it would help me lift a bit more and enable myself to push hard­er in the gym with­out burn­ing myself out too quickly.Little did I know, that half way through­out my work­out I would be pulling 10 plates on the row machine when I was only used to 6 and dead­lift­ing 160kg with­in the 4th week of my gym rou­tine. I hon­est­ly felt like I was nev­er fatiguing.If you’re in need of a kick and require the ener­gy to get through your work­out, this will help you achieve that goal. It con­tains var­i­ous amino acids which con­tribute to the main­te­nance and growth of mus­cle and pre­vents the body mus­cle break down.The cre­a­tine in this will help pro­vide your mus­cles with ATP, the ener­gy required to lift more in the gym and you will start to fatigue less quickly.The caf­feine is 175mg and has an effect on the cen­tral ner­vous sys­tem, pro­vid­ing you with the ener­gy you need to lift.The sup­ple­ment is “gold stan­dard” so you know you’re get­ting the ingre­di­ents list­ed on the tub. I advise that you do not use pre work­out too often for every work­out as its easy to build a tol­er­ance to caf­feine, mean­ing you won’t get the same effect every time you workout.The pre work­out also tastes pret­ty good, quite sweet and chem­i­cal­ly but it doesn’t taste too bad, you get used to it.I high­ly rec­om­mend this.

  7. Daniel Eldridge

    Would only rec­om­mend for new­bies not old dogsNot sure I can say much about the effec­tive­ness of Thai prod­uct, it gave me a buzz for a while of 5 min­utes, if you are new to the gym world then yeah give it a go but if you are an old dog then i would advise using some­thing more potent, I main­ly bought this as it was on offer and real­ly wish I hadn’t.

  8. Otto

    great pre-work­out pow­dergreat prod­uct ; does the job ; taste nice and not chem­i­cal ; i love the fruit punch fla­vor ; much bet­ter than the water­mel­on which i tried as well. i take it approx 30 min before my work­out; just make sure you dont take it too late at night, oth­er­wise you might strug­gle to sleep with the caf­feine! def­i­nite­ly recom­mand this product

  9. YupYupH

    Great flavour, feel the boost, but do not use it long termthis is a great sup­ple­ment for when i want ot get a heavy work­out in. espe­cial­ly in morn­ings when i am tired. But do not use this often, it has a very high dosage of caffiene, so if you use it reg­u­lar­ly, after 2 weeks take a 1 week break. it is not rec­om­mend­ed for long term use so only use it rarely.

  10. Ðemô

    Dis­ap­point­edDoes noth­ing for me so I can’t give it any­thing above a 1 starNo increased ener­gy, focus or anything.I can imag­ine it will work for oth­ers but much more effec­tive PWO out there for me. Being a good brand I though I would try this and I am very dis­ap­point­ed indeed.The scoop is 11g so its a hefty scoop already, I might get some­thing from 2 scoops (as opposed to the rec­om­mend­ed 1) but then this becomes real­ly bad val­ue for money.The water­mel­on taste is alright though.
