Mass Gainers

High-calorie mass and weight gainers that combine protein with carbohydrates in a single shake, in tub sizes from small tubs up to bulk sacks.

The point of a gainer is that drinking calories is easier than eating them. Compare three numbers before choosing: calories per serving (often 400–1,300), the protein-to-carbohydrate ratio, and the serving size itself, because a "1,000 calorie" shake can mean four or five scoops and a lot of liquid. Lean gainers sit lower on carbs; classic gainers go heavier. Many people get the same result more cheaply by mixing their own protein powder with carbohydrates, which also lets you adjust the ratio.
