Customer Reviews (4.6 / 5 · 67 reviews)

Zoe ★★★★★

The chocolate powder mixes up surprisingly smooth with milk, and the 6-pound tub lasts me over a month of daily shakes. The creatine and zinc in the formula make it an easy all-in-one for my post-workout routine, and I’ve actually put on a few pounds without feeling overly bloated.

Adam ★★★★★

Took a while to get used to the thickness, but once I started blending it with milk instead of water, it went down easy. Six pounds lasts me about three weeks and the creatine in the mix means one less supplement to buy.

Penelope ★★★★★

The chocolate flavor mixes really smoothly with just milk, no clumps at all. Got me past a stubborn weight plateau after two weeks of consistent use.
