  • Explosive training energy and razor-sharp focus from a high-impact pre-workout formula.
  • Push harder for longer—beta-alanine supports performance when the reps start to burn.
  • Powerful 6 g L-Citrulline supports nitric oxide levels for epic pump and drive.

Optimum Nutrition Platinum Pre-Workout: Advanced Power For Your Toughest Sessions

When you’re chasing PBs, average won’t cut it. Optimum Nutrition Platinum Pre-Workout is engineered for lifters, runners, and competitors who demand more from every set and stride. Each serving delivers 6 g of L-Citrulline, 3.2 g of Beta-Alanine, and 200 mg of natural-source caffeine—a serious line-up designed to prime your body and sharpen your mind before you even touch the bar.

Why you’ll love it

This is pre-workout done right. The formula combines research-backed dosages to support performance from multiple angles—energy, focus, drive, and pump. L-Citrulline supports nitric oxide levels for that locked-in, ready-to-go feeling; beta-alanine helps you keep pushing when intensity climbs; and natural caffeine delivers clean, reliable alertness without the faff. You’ll also get smart support from vitamins B6, B12, niacin, and pantothenic acid, which contribute to normal energy-yielding metabolism—ideal on heavy days, interval sprints, or long grind sessions.

Built for your kind of training

  • Strength & hypertrophy: Prime for volume and heavy sets with a formula tuned for performance.
  • HIIT & circuits: Stay switched on from first round to last with dependable focus.
  • Endurance work: Support sustained output when pace and effort matter.

Flavours you’ll actually finish

Choose your go-to from four bold flavours: Tropical, Sour Gummy, Fruit Punch, and Blue Raspberry. Smooth, refreshing, and easy to mix—so it’s one less barrier between you and a great session.

What’s inside the scoop

  • 6 g L-Citrulline to support nitric oxide levels and training performance.
  • 3.2 g Beta-Alanine to support high-intensity efforts.
  • 200 mg natural-source caffeine for increased alertness and improved concentration.
  • 3 g L-Leucine plus a blend of amino acids and B-vitamins to support your routine.

Its good but just not for me

As a user of ON's normal pre-workout I decided to give this a try, after all it the standard pre workout they do is excellent then I hoped this would excell it - for me that wasnt the case...

I have tried both the fruit punch and tropical varieties over the summer - no issues with taste and they mix all well as the original in a shaker bottle.

Time for them to kick into action is about the same - 20-25 mins so nothing different there.

Unfortunately for me all the positives of the original formula was kinda lost on this cos as good as it is, and I'll be honest and say its good, its perhaps not what I am looking for in a pre workout...

The main issue which really stood out for me is the excessive sweating this caused - even before I started working out, and if I was doing a cardio session then the feeling and sweating I got while warming up on the spin bike was bordering on uncomfortable . For some that might be what they want but not myself, I also had a issues with bloating about 5 mins after taking, even tried dialing down the dosage to see if that made a difference to the aforementioned issues I encountered but without success.

So I'll stick to the tried and trusted formula of the original for now!

Rocket fuel!

This was my first time trying pre-workout. I've previously avoided it as I've been trying to cut caffeine out of my diet but wanted to try taking my workouts to the next level, if only out of morbid curiosity. I made the mistake of not using enough water when I mixed the powder, so the resulting drink was VERY acidic when I drunk it; Optimum Nutrition recommends mixing one serving of three scoops into 400ml of water and this should be heeded.

My body's reaction to taking the supplement was immediate. Within minutes, I was having hot flushes and could not sit still, becoming restless and twitchy. I felt a tiny bit nauseous too but not anywhere near the level where there was even a remote risk that my body wouldn't be able to keep the pre-workout down.

Immediately wanting to put this sudden burst of energy to use, I began my workout. I'm a cardio person and my exercise of choice is cycling on the stationary bike, seeing how far I can go in an hour-long ride. As soon as I started peddling, I noticed how light my legs felt and very quickly found myself hitting a fast pace by my own standards. I was able to maintain and even slowly increase this pace for the full duration of my session, smashing my previous PB by half a mile.

Pre-workout is not a joke. It definitely increased my performance and I plan on using it semi-regularly as part of my exercise routines in such a way where I do not create a tolerance or dependency on it.

Strong. Very strong.

When they say advanced they mean it. If you're used to regular gold standard or other pre workouts try 1 or 2 scoops first and DO NOT BE A HERO with the recommended 3 scoops. I genuinely feel like a 2/3 scoop of this is more intense than a double dose of some others I've used. Everyone who I've given some to try has told me that night was sleepless and the workout was intense and focused, and I agree. This let's you push harder than you thought, and the pump is crazy. I recommend if you are used to your regular scoop and feel like you're up to it. Stay hydrated.

The taste however, it's safe to say that I won't be tempted to sip on this for the flavour. If the energy it puts into you had a taste, it's this. This tastes like a lightning strike and not in a good way, but the results are worth pushing through it and drinking it fast, if you're at this stage of buying advanced/expensive pre workouts you're probably more than used to bad tasting supplements anyway, but if flavour matters to you, this really is not the one for you.

Pre-workout

I used pre-workout for the first time for my after work training which is between 6-7.pm After about 10 minutes of taking it, I experienced itching all over my body, quite unpleasant, fortunately it only lasted about 5-10mins max. During my training I must say I did feel an increase in performances, I felt less tired and more able to push myself. Another down side to using in the evenings was I struggled to sleep . I went to bed about 11.30 and was tossing and turning until 3.30 ish. So feeling tired the day after. I only had 1 scoop, not sure if I could reduce the amount and still get the benefits whilst training. I think using this would be ideal if you are a morning trainer

Great flavour and really give you a boost

Great product and the taste of the blue raspberry is lovely, product arrived well packaged and sealed, so far I would say it's a very effective product and I have had no side effects, definitely found my brand and will continue to purchase them as the boost to energy and quality ingredients, just make sure you read the description correctly as it had a high strength of caffeine

The best pre workout available

I've tried a lot of different pre workouts from popular name brand ones to the random unknown non-label ones and this is the best by far.

It's expensive in my opinion for what it is, but you do get what you pay for. The levels of the various active ingredients are pretty high, better than most, so it is decent value for money in that sense.

It is less caffeine dependent than most formulations so you get less of the jittery, headachey buzz and crash of other products. It delivers a nice clear alert focused workout after about 20 minutes. You do get a bit of the signature alanine tingles but nothing escessive if you're used to it.

It gives a good pump and helps to push through those challenging workouts or early morning sessions we all dread. I'd recommend using sparingly for maximum impact and to not get to acclimatised to it's ingredients.
