My post-workout coffee just leveled up.
"I use it after the gym in my black coffee. No shaker, no mess, no prep. Just drop and stir. The fact that it has 5g protein per cube and dissolves in seconds is wild."

Tastes like sweetener, works like protein.
"Honestly was skeptical. But it really does dissolve like a sugar cube and sweetens the drink while adding protein. My kids even love it in their milk."
