Collection: Mass Gainers

A mass gainer is a high-calorie shake that combines protein with carbohydrates, and often some fats. People who find it hard to eat enough food in a day use it to add calories between meals.

Our range includes Serious Mass by Optimum Nutrition, True Mass 1200 by BSN, R1 Clean Gainer by Rule 1 and Extreme Mass Gainer by International Protein. Mix with milk for more calories, or split a serve across the day.
