For what you pay, the ingredient quality is excellent. No proprietary-blend nonsense, just clearly dosed ingredients. Zero clumping, which I appreciate since my old one needed a whisk every time.
Tastes way better than I expected for a supplement; I actually look forward to taking it. For what you pay, the ingredient quality is excellent. Consistent quality across every tub I've bought so far.
Label is clear about dosing and the bottle doesn't take up much shelf space. Honestly tastes like a treat rather than a chore. Great value for the serving count — works out cheaper per dose than the big brands.
Mixes clean with just a shaker bottle — no clumps and no grit at the bottom. Recovery between sessions has clearly improved; less soreness the next day. For what you pay, the ingredient quality is excellent. The seal was broken on arrival, which made me nervous about freshness.
Resealable tub keeps everything fresh and the scoop sits right on top. Saw a real difference in my hair and nails within a month — not placebo, measurable.
Clean ingredient list with no fillers I didn't recognize — exactly what I look for. Mixes clean with just a shaker bottle — no clumps and no grit at the bottom. Far too sweet, almost cloying. I have to mask it with extra liquid.
