ON Pro Complex Gainer is designed to be a mass gain supplement. It contains faster absorbing whey proteins as well as slower absorbing casein and egg proteins, making it ideal for post workout or as a snack between meals/before bed.
Pro Complex Gainer claims to contain almost no sugar, and source its carbohydrates from complex, high fibre sources. This is slightly misleading as the source of carbohydrate in this product is maltodextrin, which is technically a complex carbohydrate but actually has a very high GI and acts like normal sugar (actually has a higher GI than sugar) and is not high in fibre. High GI carb sources are okay for post workout nutrition, but are definitely not ideal for snacks between meals or for taking before bed and will likely result in excess fat gain when consumed during those times.
Pro Complex Gainer only contains 5g of total fat (medium chain triglycerides and sunflower oil) per 165g serving, if being taken as a meal replacement or as a snack, this a poor balance of carbs, protein and fat. The ratios of protein, carbohydrate and fat and the type of carbohydrates in Pro Complex Gainer make it ideal for pre and post workout nutrition, but not to be used as a snack or meal replacement shake.
