Zoe H. ★★★★★

I’ve been blending this with oat milk and a banana for extra calories, and the powder dissolves way better than I expected without clumps. The chocolate peanut butter flavor is actually enjoyable enough to drink every day.

Thomas ★★★★★

Mixing this with whole milk makes a thick, delicious shake that actually tastes like chocolate peanut butter, not artificial. I’ve noticed real improvement in my lifting recovery since adding it post-workout.

Chloe ★★★★★

Each scoop gives me 1,250 calories which is perfect for bulking without having to eat all day, and the creatine content is a nice bonus for strength gains. I’ve noticed a solid increase in my weight after using it for a few weeks.
