The Bulk Protein Company, SERIOUS GAINZ – Whey Protein Powder – Weight Gain, Mass Gainer – 30g Protein Powders (Vanilla, 5kg)

SERIOUS GAINZ by The Bulk Protein Company is a high-calorie mass gainer protein powder designed for hardgainers and anyone who struggles to eat enough to stay in a calorie surplus. Delivering approximately 468 calories, 30g of protein and 81g of carbohydrates per serving, it is positioned as one of the high calorie drinks for weight gain, helping support size, strength and steady progress during bulking phases. Each serving combines soy protein powder, whey isolate protein powder, casein protein powder and oat flour to provide both fast and sustained amino acid release, supporting muscle recovery, lean muscle growth and improved training performance.
Formulated as a bulking protein powder, SERIOUS GAINZ can be mixed with water or milk, though many users prefer milk for a smoother, richer and more consistent texture. Adding liquid first, shaking thoroughly or using a blender helps reduce clumps and creates a creamier shake that is easier to drink during heavy bulking periods. Its naturally thick, dessert-style consistency can be customised to suit your preference—use more liquid for a lighter protein shake, blend with ice or fruit for added smoothness, or keep it dense for a more filling post-workout option. This flexibility allows you to tailor each serving to your taste, routine and daily calorie goals.
SERIOUS GAINZ is designed to support consistency, helping you meet increased nutritional demands throughout your bulking journey. The balanced combination of protein sources and slow- and fast-digesting carbohydrates helps refuel muscles, restore glycogen levels and maintain high protein intake across the day. Available in popular flavours including Chocolate, Cookies & Cream, Vanilla, Strawberry and Banana, it offers a smooth, sweet flavour experience that fits naturally into shakes, oats, smoothies and high-calorie recipes.
