Proto Size – Hardcore Mass Gainer With Creatine

Proto Size – Hardcore Mass Gainer With Creatine

Proto Size is a next-level mass-building fueling system created for lifters and athletes who are serious about size, strength, and performance gains. Developed under the Legacy Line of IFBB Pro William Bonac, this powerful formula goes beyond basic calories — it’s a scientifically advanced gainer designed to accelerate muscle growth, support hormone health, and fuel strength training from all angles.

Every serving of Proto Size is loaded with high-quality carbohydrates and proteins to help meet your caloric surplus goals without bloating or digestive stress. What truly separates it from generic gainers is its high-performance ingredient matrix.

Each serving delivers:

• 3000mg of Creapure® Creatine Monohydrate – clinically proven to boost strength, power, and muscle cell volume.

• 500mg of Tribulus Terrestris – a natural testosterone support herb that promotes strength and lean mass.

• 500mg of KSM-66® Ashwagandha – an adaptogen known to reduce cortisol, enhance recovery, and support natural anabolic hormone levels.

Combined, these ingredients don’t just help you gain weight — they help you gain the right kind of weight: dense, hard, lean muscle.

Available in a delicious Chocolate Hazelnut flavour, Proto Size blends easily, tastes great, and provides nutritional consistency in every scoop. With 38 servings in each 8.8 lb tub, it’s built for sustained use during heavy training cycles.
