Product Rating: 4/5 Writing this review after more than 5 months of consuming this same product after repeat purchases. FLAVOR: I have tried both the flavors, Green Apple and Fruit Punch. I would say Fruit Punch is almost like drinking a syrup. I don't mind the strong taste as much as I dislike the smell that lingers in your breath. Surprisingly that smell of Fruit Punch flavor stays in the shaker forever even after countless thorough washes. However, the Green Apple flavor is delicious. Both of them taste artificial but green apple is still pretty appealing and feels nice to consume daily. PERFORMANCE: The boost of energy it gives is decently good and there's no crash after the workout. DIGESTION: So far I have not faced any digestion issues. Infact, I must share that people who consume black coffee for similar caffeine boost face more bloating and stomach issues. AUTHENTICITY: Also the product can easily be verified for authenticity on the official ON website using the code on the box. Read more

Please rename the fruit punch flavour to Cough syrup flavour! P.s. Results are good though. Read more

So far so great, it is the original as the tag has been verified. ON is one of the most premium products and be sure to read the instructions before consuming. Fruit punch flavor is great but be sure to eat something before consuming or else it won't have any effect. Do not consume before going to bed. Read more

I recently decided to take Optimum Nutrition's Pre-Workout a try, and I have to say, it has completely transformed my workout sessions! As someone who often struggles with energy levels, especially during those late afternoon gym visits, I was on the lookout for something to give me that extra boost. First off, the flavor options are fantastic! I went with the Fruit Punch, and it was refreshing without being overly sweet. Mixing it was a breeze—no clumps or gritty texture, which is a huge plus in my book. Now, let’s talk about the performance. Within about 20 minutes of taking it, I felt a noticeable increase in my energy levels. I was able to push through my sets with more intensity and focus. The caffeine content is just right; I didn’t experience any jitters or crashes afterward, which is often a concern with pre-workouts. Instead, I felt energized and ready to tackle the rest of my day. I also appreciated the added ingredients like beta-alanine and creatine, which I know can help with endurance and strength. I’ve noticed that I can go longer during my workouts without feeling fatigued, and my recovery time seems to be improving as well. Overall, I highly recommend Optimum Nutrition Pre-Workout to anyone looking to enhance their gym performance. It’s effective, tastes great, and doesn’t leave you feeling wired or anxious. It’s definitely become a staple in my pre-workout routine! Read more

I am going to turn 40 this year. Every day my trainer comes to my home and makes me workout. I have some basic equipment. I have used some outstanding pre workout powders like Yeah Buddy and Kaged Preworkout. However, ON is a reputed brand and they are selling this for a very reasonable price so I had to find out what is going on. This review is being written after 4-5 uses. What does it taste like? It tastes very bad. If you don't mix well, the powder will make you want to throw up. It's very synthetic, strong. Flavour is not good. Does it mix easily? yes and no - since the serving size is quite big, the lumps inevitably remain when I use fork to mix it. Ideally you need a tall beer glass in which you should mix this with 400ml of water. Effect? No immediate high tension feeling. You will not get burning/itching sensation on your skin. Workout effect? Your focus improves. Your muscles feel ready to work. You will sweat within 20 minutes of using this. This is a standout feature. Other preworkouts may not make me sweat but this pre-workout always makes me sweat. I have managed to do 50-60 sessions with relative ease. I like this powder. Overall? For the price, quality, effect - I highly recommend it. But it could be a little more natural. But O.N does not make natural products. Kaged is way more natural than this. But it is not easily available and the sellers are suspect on amazon. **UPDATE 17th October 2024** I am on my second box and want to just say the taste improves over time. The effect is not as good as more expensive Preworkouts but on a single serving you will get a decent blast for 30-40 minutes. Don't expect to do 90 minute marathon sessions with this. For the price this could also be a 5 star product. Read more

I've been using ON Gold Standard Pre-Workout for a few weeks now, and it’s easily one of the best pre-workouts I’ve tried. It gives me a noticeable energy boost within 20–30 minutes without making me feel jittery or overstimulated. Perfect for early morning workouts or days when I need that extra push. The flavor (I got Fruit Punch) is surprisingly good—not overly sweet or artificial—and it mixes well with water. No clumps, no gritty texture. I also really like that it includes ingredients like beta-alanine, caffeine, and creatine, all in well-balanced amounts. The focus and endurance I get from this are excellent—I can push harder through my sets without feeling drained halfway through. No crash afterward, and no upset stomach, which is a big plus for me. Definitely sticking with this one! Read more
