Started noticing better recovery after about two weeks of consistent use. Dissolves completely in water, even without a blender. Resealable tub keeps everything fresh and the scoop sits right on top.
Consistent quality across every tub I've bought so far. Sleep quality went up almost immediately, which is exactly what I wanted. Resealable tub keeps everything fresh and the scoop sits right on top.
Label is clear about dosing and the bottle doesn't take up much shelf space. The flavor is genuinely good — not chalky or overly sweet like a lot of others I've tried. The price-to-quality ratio here is hard to beat; I've already reordered twice.
Arrived sealed and well packaged, with a scoop that was actually easy to find. You can tell this is a quality formulation; transparent labeling and third-party tested. Cost per serving is lower than my old brand and the quality is at least as good.
