No proprietary-blend nonsense, just clearly dosed ingredients. Sleep quality went up almost immediately, which is exactly what I wanted. Finally one that doesn't taste artificial. The vanilla is subtle and pleasant.

Recovery between sessions has clearly improved; less soreness the next day. Arrived sealed and well packaged, with a scoop that was actually easy to find. Clumps badly no matter how long I shake it; gritty residue settles at the bottom.

Smooth flavor with no weird aftertaste, which is rare in this category. Sleep quality went up almost immediately, which is exactly what I wanted. Not worth the premium — comparable products cost less per serving.

Dissolves completely in water, even without a blender. Label is clear about dosing and the bottle doesn't take up much shelf space. Tastes way better than I expected for a supplement; I actually look forward to taking it.

Good value compared to what I was paying before, and the quality is at least as good if not better.

Bought this on a recommendation and I'm really impressed. Quality is obvious from the first use.
