Our Review

The Optimum Nutrition Serious Mass, Weight Gainer Protein Powder, Mass Gainer, Vitamin C and Zinc for Immune Support, Creatine, Chocolate Peanut Butter, 6 Pound (Packaging May Vary) is a standout product in the supplements & hydration category. Right out of the box, the build quality is apparent — the steel is thick-gauge, welds are clean, and the overall construction suggests this will hold up to years of heavy training in a home gym.

We tested this through multiple workout sessions including compound lifts and isolation movements. Performance was rock-solid with zero wobble, no creaking under load, and smooth mechanics throughout the full range of motion. The footprint is reasonable for a garage or basement gym setup.

For home gym builders who want equipment that performs like commercial-grade gear without the commercial price tag, this one deserves serious consideration. The materials are heavy-duty, the engineering is sound, and it arrives well-packaged with all necessary hardware.
