What Is a Mass Gainer?

A mass gainer is a high-calorie supplement built to help you increase body weight and muscle size.
It combines carbohydrates, proteins, healthy fats, vitamins, and minerals to support intense training and recovery.
Perfect for anyone struggling to meet calorie demands through food alone — especially when paired with a consistent diet and training plan.

The CBUM Standard — What Sets It Apart?

Most gainers overload on maltodextrin and sugar. Not this one.
Here’s what makes CBUM Mass Gainer different:

• 1070 kcal per serving to fuel even the toughest workouts

• 196g of clean carbohydrates

• 53g of high-quality protein

• 2,500mg of Creatine for power and performance

• 2,500mg of Glutamine for recovery and muscle preservation

• Vitamin A and other essential nutrients

Instead of maltodextrin, CBUM Mass Gainer uses Carb10™ — a fast-digesting, plant-based carbohydrate derived from pea starch, delivering clean, sustained energy without sugar spikes or crashes.This makes it ideal for athletes, busy trainers, and anyone focused on clean bulking.

When to Take It

• Post-workout to replenish glycogen and fuel recovery

• Between meals to meet daily calorie goals

• Anytime you need extra fuel to support mass and muscle growth
