Great deal on a great brand

Creatinine is so underused but is a great supplement supported by vast research. It's also not expensive to produce so I never like that companies mark it up so much. ON is generally a trustworthy brand and this price at Sam's was too good to pass up. I fear it was on clearance though, so I stocked up!

On Nutrition is a great product.

I’ve tried different brands, cannot honestly say there is a big difference if one works better than the other. What I do like better, ON is not actually a powder like the last brand I tried which makes it mix and dissolve better.

Excellent

Product does not include teaspoon. I understand environmental awareness but it could be a different material design (biodegradable) and always offer this to customers.

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. We've shared your feedback for biodegradable options with our internal teams!

Creatine

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

Rounded teaspoon?

Not exactly sure what a rounded teaspoon means.. otherwise, I love it.. I can definitely feel a difference in my body when I take it consistently.

Just OK

First time trying creatine but this one does not dissolve completely. Not sure if all creatine is like that or just this brand. Not sure I would purchase again.

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.
