Optimum Nutrition Gold Standard Pre Workout Advanced, with Creatine, Beta-Alanine, Micronized L-Citrulline and Caffeine for Energy, Keto Friendly, Berry Blast, 20 Servings

The delivery was outstanding. However, the product's price seems excessively high, making it appear overvalued. No real benefit.

Me encantó, me da muchas energías para entrenar, sin duda lo volvería a comprar

I had been purchasing the regular version of Optimum Nutrition Gold Standard for about a year now mainly because it's ingredient list is simple and to the point of what I wanted (caffeine and creatine) - when I saw this Advanced version on the site and decided to give it a try. Holy hand grenades this stuff is miles more effective (due to the additional caffeine and other ingredients) than the regular version. If you aren't getting the same kick from the regular version, I'd highly suggest giving the Advanced version a try. It kicks in fairly quickly, I'd say in about 15-20 minutes post consumption. A full scoop is 300 mg caffeine which instantly perks you up, but did not give me that jittery/tingly feeling. The full benefit of this pre-workout comes half-way through your workouts (I usually do 60-75 minute weight lifting focused workouts). Typically at about the 45 minute mark, I'm absolutely gassed and have to struggle through the last 15-30 minutes, but not with this stuff... you can just keep going, seriously. I definitely also am seeing the "pump" more and able to crank out a last rep or two better than before so all in all, this stuff seems to keep my energy levels at a coasting high throughout the entirety of my workout, allows me to feel the "pump" more in my muscles, and gets me one more rep... which all equate to more gainz per sessions. Damn fine product. I'm a relative noob when it comes to pre-workout supplements, but others have told me that the ingredient list in this Advance version of the product is the tride-and-true formulation of pre-workout powders that other (much more gimmicky and expensive) brands have been using for years. Buy this.

I've been using pre-workouts for years, but Optimum Nutrition's Gold Standard Pre Workout Advanced is a game-changer. This formula delivers the perfect blend of ingredients to take my workouts to the next level. Energy and Focus for Days: The 300mg of caffeine provides a clean, sustained energy boost that lasts throughout my entire workout. No jitters, just pure focus and drive to push myself harder. Power Through Every Set: The combination of creatine, beta-alanine, and L-citrulline is phenomenal. I'm noticing significant gains in my endurance and those last few reps on each set feel much stronger. Plus, the muscle pumps are incredible! A Delicious Bonus: Let's not forget the taste! I'm currently alternate between the Berry Blast and the Strawberry Mango Daiquiri flavors, and it's seriously delicious. It mixes easily in water and tastes refreshing, unlike some chalky pre-workouts I've tried. Overall, Optimum Nutrition Gold Standard Pre Workout Advanced is a top-notch pre-workout. It's effective, delivers great results, and even tastes fantastic. Highly recommend!

I have enjoyed the ON pre-workout mixes such as blueberry lemonade, green apple, and watermelon flavors. This berry blast flavor is not very good in my opinion. I believe that I have seen some benefits in workout performance from this mix. Be mindful that this is only 30 servings and not 60 that you would get with the larger size of ON pre-workout mixes.

My favorite pre-workout currently. I wish they had a slightly lower caffeine version that did not cut back on the other ingredients as well.
