Flavor is good but it doesn't mix well and alway settles at the bottom. Been mixing and chugging followed by a chaser to get the gritty out of my mouth. Flavor is good though. Not noticing a ton of effect but still early. Really just wish it would mix well

I've used creatine for several years now, trying out both the capsulated and powdered versions. Always used before and after workouts with plenty of water and seen great results. with this product in particular, I've noticed that while it's easy to consume, I personally couldn't see much of a change in physique and energy compared to when I would take the standard powder scoops. perhaps it's the difference in ammount being taken. In conclusion I would recommend this product to beginners and pros alike but still push for the purchaser to consider trying the powdered versions.

Prefer the pills over powder

Like almost all perimenopausal women, I'm concerned about sarcopenia, brain fog and have been taking creatine. First I used powder in my breakfast smoothie but then got tired of only ever having a smoothie for breakfast. Then I put in my coffee, but I could taste it and missed actually enjoying my coffee. The gummies are too expensive and extra sugar, so these capsules fit the bill well. Easy to take, no weird after taste. Will continue to use them.

So far so good!

I've only used this a couple times but so far so good! Muscle mass is improving and recovery is easier. One less star because it doesn't dissolve as well in room temperature water as I had hoped. I definitely feel a difference when I take it before a work out.

Good from what I can tell

Started taking these a little over a month ago and noticed a slight difference in my workouts about 3 weeks in. It seemed to be most helpful on my bench reps specifically, but I am hoping it is benefiting my recovery as well as I was struggling with soreness. My training is a little dialed back currently but I am less sore and seem to be able to do a few extra reps in the gym. Only being able to order from them once every 90 days means I will need to find another source for my next batch which is annoying.

Verified Purchase

Creatine

It does what its supposed to do. Doesn't dissolve as much in water as other brands, but does the job

Pull this from the shelves Sam…

This stuff is absolute garbage. Crystals the size of sugar that doesn't dissolve. Terrible bloating feeling after drinking. By far the worst I have ever bought.

Creatine is a product that does not fully dissolve, so rest assured that this is completely normal. Note that creatine should be consumed immediately upon mixing.

I use this daily and with consistent use creatine is the best supplement you can take. Using Optimum Nutrition, I am confident that what is on the packaging is exactly what I'm putting in my body.

Where is the measuring spoon?

Am I the only one still looking for the measuring spoon? I would at least expect some sort of measuring apparatus. I have different sizes of spoons. Do I really need to weight it every single use?

As part of ON's effort to be environmentally conscious and reduce plastic, our Creatine Powder does not come with a scoop. The serving size for this product is one rounded teaspoon.
