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

This is my alternative to a coffee drink in the evening before a work out. Has a good kick and I don’t use the full scoop. It mixes very well with water and taste good and easy to take down.

Recently got into pre-workout and got the original C4 formula (silver/yellow) blue raspberry flavor, and it worked well for me since I wasn't used to pre-workout. But my friends were saying that one isn't that good and I should try something more hefty. Decided to try this brand out because I use their protein powder and it is good quality. Flavor I thought I wouldn't like (strawberry daiquiri), but it is actually pretty good. Gives a good boost, no negative side effects for me. More energy, tingly body feelings within the first 30 minutes. I would recommend.

If you’re new to pre-workouts or restarting your workout regimen start with 1/4 - 1/3 of the included scoop. Years ago I use the original/basic formula, and though it gave me a boost, it wasn’t enough to get me through my 2 to 2 1/2 hour workouts. Now that I’m starting over I’m only exercising for 30 minutes or so and find a whole scoop to be way too much. Hours after I was still feeling the intensity of the formula. Also do not take any afternoon or evening - mornings only. I took mine in the afternoon. It is now late in the evening and I am still feeling “wired” . If you found that you’ve taken too much don’t panic. Either eat something and/or drink a lot of water to flush out the pre-workout out of your system. It really REALLY gives you the umph you need to get through your workout. It isn’t the best tasting stuff, but as far as pre-workouts are concerned, the flavor is pretty good. Hope this helps!

First of all people keep complaining about the itchy and or tingling feeling you get. It has BETA- Alanine in it. Beta-alanine works by combining with histamine to create carnosine, a molecule that's stored in your muscles and brain tissue. Carnosine buffers the decline in muscle pH, which can result in greater muscle elasticity. Beta alanine causes a tingling sensation, often referred to as "paresthesia", because it activates specific nerve endings in the skin by interacting with certain receptors, essentially triggering a signal that is perceived as a tingling feeling; this occurs when the body ingests a high dose of beta alanine, which is often found in pre-workout supplements, and is generally considered a harmless side effect. So if your pre workout has this in it, you may get the feeling of itching or tingling. I happen to like the feeling because it lets me know that it’s time to start working out. After I really get my heart rate up and lifting, it goes away for me. I only take a half a dose and it works great for me but I’m also not a caffeine fanatic.

This stuff is great. has great kick and lasted me about 2 1/2 hours strong

Love this stuff. Works great.

Great product love the itch it gives!! Gets you amped everytime.

So I got this to use before going to the gym for weight training. I followed the directions to a T and was on my way to the gym and started shaking, felt hot, and was very very itchy. It may be that I am just not used to this type of product but after that I never used it again. Besides my reaction to it the flavor was good so it has that going for it.

tastes good best pre workout ive had in a while.

Powder came crystallized. Had purchased before and was fine. Got a faulty batch

I usually use strong pre-workouts (Total War worked great for me), but this one was not a good experience at all. I didn’t get any pump and the energy felt sharp and uncomfortable instead of motivating. During and after the workout I felt extremely irritated instead of calm focus, sharp spike- anxiety crash, emotionally bad, which has never happened to me before. I couldn’t calm down for a long time. My husband also tried just half a scoop and he said he felt weird and didn’t like the feeling either. Unfortunately, this just didn’t work for us.
