The Best Mass Gainers of 2022

When you’re on a mission to put on weight, you need a one-two punch of calories and protein. If you’re someone who struggles to put on weight, or who needs to gain it for a sport or a weight-classed competition, then you need both even more!

That’s when a mass gainer can be your best friend. Like the best protein shakes, mass gainers (also known as weight gainers or gainer shakes) are full of muscle-building amino acids and protein, but they also add carbs and other nutrients to maximize your calorie and macro intake.

Adding a high-quality mass-gainer powder can make a huge difference in your bulking regimen. Here are 10 of the best, according to our experts and community members.

How We Choose the Best Mass Gainers

Our picks are informed by our team of fitness pros—athletes, nutrition professionals, and editors—and backed up by reviews from the people who know gainer shakes the best: you!

There are a few things that matter when you’re looking for a good gainer shake:

Formula: It’s important to choose a formula that has the numbers you need to support your goal, not just a bunch of fillers and poor-quality ingredients. Yes, a gainer is far more decadent than a traditional protein shake, but the label shouldn’t make it feel like a candy bar in a glass.
Flavor: Gainers are there for you when you need nutrition but aren’t necessarily hungry, so the more appealing they are, the easier it will be to keep downing them every day. Plus, gainer serving sizes tend to be significantly larger than a normal shake, so one that doesn’t go down easily won’t cut it!
Customer Ratings and Reviews: Our Gym2k.com community members are some of the most discerning and honest anywhere, and that’s why our ratings carry more weight—so to speak—than most online storefronts.
Value: The lowest priced gainer isn’t always the best value! All of our best weight gainers factor in the price per serving.

Should I Take a Mass Gainer?

Anyone can go to the gym and improve their fitness, but adding significant muscle mass to your body can be surprisingly difficult. When it comes down to it, it’s just hard to shovel in the ultra-high levels of nutrients and calories you need from food alone—and in the right ratio of protein, carbs, and fats to grow muscle and not just pack on body fat. If you’re lifting weights but not feeding your muscles adequately, they probably aren’t going to grow.

Weight-gainer shakes make it easy to gulp down a lot of calories very quickly. (So do milkshakes and soda, but they won’t give you the clean gains you’re after.) Supplementing a healthy, plentiful diet with a mass gainer is your best bet to make sure your body is working up to its muscle-building potential.

Just remember, a well-designed muscle-gain training program is essential to help put those calories to good use. These are the ones our community swears by:
