Great value for the serving count — works out cheaper per dose than the big brands. Packaging is sturdy and the freshness seal was fully intact on arrival.
Started noticing better recovery after about two weeks of consistent use. Smooth flavor with no weird aftertaste, which is rare in this category.
Sleep quality went up almost immediately, which is exactly what I wanted. Cost per serving is lower than my old brand and the quality is at least as good. Honestly tastes like a treat rather than a chore.
