Adam E. ★★★★★

The slow-digesting aspect is exactly what I needed—I drink it before bed and wake up feeling like I actually recovered overnight. It mixes thick and creamy with just water, which I’ve come to like as a dessert-like finish to my day.

Eli I. ★★★★★

I mix mine with a little warm milk about an hour before lights out, and the slow-digesting factor really does keep me feeling full until morning. It's become the last thing I reach for every night, no exceptions.

David ★★★★★

Stirred this into cold water before bed and it actually mixed clean with just a spoon, no clumps stuck to the glass. Three nights in and I'm waking up noticeably less sore after evening lifting sessions, which is exactly what I needed for the slow-release recovery.
