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.

in my hot coffee or using a quality hand blender in my protein drink it blends just fine and no after taste to me.

Good deal, doesn't dissolve.

Great deal but creatine doesn't dissolve fully. Maybe 80% dissolves %26 the rest you have have to add more water and keep shaking

Wanted to love it but can't

Does NOT dissolve at all what so ever. I've tried everything and nothing works. You're left with a gritty texture

Gritty and doesn't dissolve

I've taken several brands of creatine. This is the worst creatine I've ever taken due to its grittiness. It doesn't dissolve at all, even when mechanically blended in. It's so bad I'm going to try to return it
