Key Features

The information below applies to each unit in the pack

HIGH-CALORIE MASS GAIN FORMULA WITH 30G PROTEIN PER SERVING – SERIOUS GAINZ by The Bulk Protein Company is positioned as one of the high calorie drinks for weight gain, delivering approximately 468 calories, 30g protein and 81g carbs per serving to help hardgainers stay in a consistent calorie surplus. Designed for anyone needing extra calories to increase size and strength, it supports muscle recovery, training performance and progressive weight gain when paired with a structured eating plan.

SUPPORTS MUSCLE GROWTH & POST-WORKOUT RECOVERY – Each serving provides a balanced blend of protein and carbohydrates to replenish energy after training and support lean muscle growth. The combination of soy protein powder, whey isolate protein powder, casein protein powder and oat flour delivers both fast and sustained amino acid release, helping refuel muscles, restore glycogen levels and maintain a high daily protein intake for better recovery and improved performance between sessions.

MIXES BEST WITH MILK FOR A SMOOTHER, MORE ENJOYABLE SHAKE – As a bulking protein powder, SERIOUS GAINZ can be prepared 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’s easier to drink during heavy bulking phases. This preparation method makes each serving more enjoyable and supports daily consistency as calorie needs increase.

SMOOTH, SWEET FLAVOUR EXPERIENCE YOU CAN ENJOY DAILY – This whey protein powder delivers a rich, dessert-style taste that makes each protein shake enjoyable as part of your daily bulking routine. Available in popular flavours such as Chocolate, Cookies & Cream, Vanilla, Strawberry and Banana, it offers options suited to both classic and dessert-style preferences. Whether you mix it with water or milk, or blend it into oats and smoothies, the flavour stays satisfying across long bulking phases.

FILLING FORMULA DESIGNED TO HELP MAINTAIN A DAILY CALORIE SURPLUS – This mass gainer delivers a dense, satisfying shake that helps men and women stay on track with daily calorie targets during bulking phases. Its naturally filling consistency supports a sustained surplus, while starting with smaller servings, adding more liquid or spacing intake can help maintain comfortable, consistent nutrition throughout the day.
