No proprietary-blend nonsense, just clearly dosed ingredients. Great value for the serving count — works out cheaper per dose than the big brands. My energy through the afternoon is noticeably more stable since I started this.
Mixes clean with just a shaker bottle — no clumps and no grit at the bottom. For what you pay, the ingredient quality is excellent. My energy through the afternoon is noticeably more stable since I started this.
Blends smooth in seconds; texture is consistent every scoop. Started noticing better recovery after about two weeks of consistent use.
My energy through the afternoon is noticeably more stable since I started this. Blends smooth in seconds; texture is consistent every scoop. Label is clear about dosing and the bottle doesn't take up much shelf space.
Sleep quality went up almost immediately, which is exactly what I wanted. Honestly tastes like a treat rather than a chore.
Tastes way better than I expected for a supplement; I actually look forward to taking it. You can tell this is a quality formulation; transparent labeling and third-party tested.
