Optimum Nutrition Gold Standard Pre-Workout Powder: I purchased this for my Son to use before lifting weights but he didn’t like it. My husband, who works out at the gym 5 days a week, decided to give it a try as he’s never tried such a thing. He loves it! I put one scoop in a 32 ounce water bottle the night before. I feel by doing this it gives the powder time to truly settle. It does call for mixing it in 6-8 ounces of water. I think the strong taste that some reviews write about is due to it being in too little water. 32 vs 6-8 is quite a difference but it works perfectly for my husband. He loves blueberries & says the taste is just right with it being in 32 ounces of water. He feels it would be too strong if it was in 6-8 ounces. He begins to drink it on the way to the gym. He tells me within less than 5 minutes he feels an energy boost like he never had before. The mixture of caffeine, creatine monohydrate & beta-alanine is just right to provide the necessary stamina to begin his workout routine. He finishes off the water bottle as he begins to work out & reverts to regular water. He loves the energy & focus this provides. What I love about this powder is the added supplements. My husband isn’t one to take a men’s multivitamin. I’m all for it. This powder has Vitamin D, Thiamin, Niacin, Vitamin B6, Folate, Vitamin B12, Pantothenic Acid & Calcium. All great supplements for a man who doesn’t take a multivitamin! For all the positives this offers the price is well worth it! This is now a permanent staple in his workout regime. He says he feels a workout high he hadn’t before. A win-win! I utilize Amazon’s subscribe & save so I save a little more $ & it comes automatically each month. I’m so happy this worked out to be such a great benefit. From my husband’s experience & from my love of the additional supplements I definitely recommend!

I have been taking this pre workout for about 2 months now and it has definitely made a difference. I do CrossFit and before I started taking this I was getting gassed out during my workouts and just felt like I needed an extra boost to help me out. Since I've started taking it I can push my self harder through my workouts and feel like I have more energy. It taste great just like sour green apple and I don't get any tingles or jitters. I am very happy with this pre workout.

This stuff is pretty good. The taste isn't horrible and best of all it works. It gives me a good boost before going to the gym. I just cant take it after 3pm or it will keep me awake all night.

Flavor Name: Fruit Punch
Size: 30 Servings (Pack of 1)
The Optimum Nutrition Gold Standard Pre-Workout has become my go-to supplement for enhancing my exercise performance and pushing my workouts to new heights. With its powerful blend of key ingredients, this pre-workout formula consistently delivers the energy and focus I need to power through intense training sessions. One of the standout features of this pre-workout is the inclusion of creatine, beta-alanine, and caffeine. The combination of these three ingredients is a game-changer. Creatine helps boost muscle strength and power, allowing me to lift heavier and perform better during resistance training. Beta-alanine minimizes fatigue and supports endurance, giving me the stamina to last longer during high-intensity workouts. The caffeine content provides a much-needed energy kick, improving mental alertness and focus, especially when I'm feeling tired or drained. The fruit punch flavor is absolutely delicious and refreshing, making it a pleasure to consume before each workout. I find that it mixes easily with water, leaving no clumps or residue behind. The 30 servings per container offer great value for money, especially considering the effectiveness of the product. Each serving provides just the right amount of energy without making me feel jittery or overstimulated. What sets this pre-workout apart from others I've tried is the absence of any unnecessary fillers or proprietary blends. With Optimum Nutrition, I know exactly what I'm getting, and the transparent labeling gives me the confidence that I'm fueling my body with high-quality ingredients. As someone who enjoys both weightlifting and high-intensity interval training, I can confidently say that this pre-workout supports my performance in both disciplines. I have experienced increased strength, endurance, and mental focus since incorporating it into my routine. I appreciate that this pre-workout doesn't lead to a crash after my workout. The clean energy it provides helps me finish strong and leaves me feeling energized throughout the day. In conclusion, Optimum Nutrition Gold Standard Pre-Workout is a top-tier supplement that lives up to its name. It provides a balanced blend of essential ingredients that enhance performance and keep me motivated during my workouts. The fantastic taste, quality ingredients, and noticeable results make it a must-have for fitness enthusiasts of all levels. If you're looking for a reliable pre-workout to take your training to the next level, this product is the gold standard!

I was using another brand, but I hated the jitters and tingles, so since I already use Optimum Nutrition protein, I decided to try this. First and foremost no Tingling or jitters, that alone is 5 star worthy. I usually make it the night before and put it in the fridge (I like cold drinks) I'll drink it on my way to the gym and by the time I have stretched you can feel it. I would recommend this and have recommended it to my friends, it is great and I do love the blueberry flavor.

The flavor is good, but does not fully dissolve. The more you shake it, the more foam sits on top, but still leaves grit in my teeth. Works well, I suppose, just can’t wait to finish it so I can buy something else.

This is the best pre-workout I've tried. I just feel like I have more energy to workout. Others make me feel jittery or on edge, but not this one. The fruit punch flavor is a bit strong, but I honestly like it a lot. It takes a bit of stirring with cold liquid, but it isn't gritty and it's easy to drink.
