Best Mass Gainers of 2022

If you want to build mass quickly, you need a mass gainer supplement.

Mass gainers are specialty protein powders packed with calories, carbs, and other ingredients needed to maximize muscle development.

Some people take mass gainers because they struggle to gain weight. Others take mass gainers to support a strenuous workout program and maximize muscle growth.

You have plenty of options for mass gainers. We tested the world’s best mass gainers. Here’s what we found.

Crazy Nutrition Mass Gainer


Crazy Nutrition Mass Gainer is one of the best-known names in the mass gainer supplement space. At around $35 per tub, it’s also one of the best-value options on our list.

Featuring 695 calories, 50g of protein, and 100g of clean carbs per serving, Crazy Nutrition Mass Gainer can help you pack on gains fast without erratic blood sugar spikes, gas, or bloating.

Mix six scoops (yes, six) of Mass Gainer with 15oz to 20oz of water, then shake and drink daily to optimize workout results. Whatever your goals are, you can gain mass using Crazy Nutrition Mass Gainer.

We also like how Mass Gainer contains ingredients specifically to help with digestion, including a blend of digestive enzymes like amylase, protease, cellulase, lactase, and lipase to help you process the carbs and proteins.

Although the price seems cheap, it’s important to note that there are only five servings per container (200g / 6 scoops per serving). However, that’s still a lot of protein powder for a reasonable price.

Transparent Labs Mass Gainer


Mass Gainer from Transparent Labs is another well-known and well-rated supplement company in the mass gainer space. Featuring 730 calories, 106g of carbs, and 51g of protein per serving, Mass Gainer seems to have been explicitly formulated to beat the top-ranked mass gainer supplement on our list, as it edges out Crazy Nutrition Mass Gainer in every category.

Available in two flavors (Sweet Vanilla and Chocolate Glaze Donut), Transparent Labs Mass Gainer contains 15 servings per container (2 scoops / 196.76g per serving).

Transparent Labs Mass Gainer uses grass-fed whey concentrate, coconut milk powder, natural chocolate flavor, cocoa, medium-chain triglycerides, fiber, creatin, prebiotics, and other proven ingredients to pack on the carbs and calories.

With a diverse blend of proven, natural ingredients and a surprisingly high-quality formula, Transparent Labs Mass Gainer is one of the best options available today.

Xwerks Grow


Xwerks Grow is a 100% New Zealand grass-fed whey protein isolate powder designed to help you build muscle mass. Although it’s not explicitly marketed as a high-powered mass gainer, it’s a good option for those who want muscle-building effectiveness in a proven blend.

By taking Xwerks Grow daily, you can enjoy superior muscle repair, muscle growth, and immunity, among other perks. Xwerks has also designed its formula to be easy to digest with no bloating. And, by using whey protein isolate instead of cheaper protein sources, Xwerks Grow maximizes absorption over more affordable mass gainer formulas.

If you’re looking for massive doses of carbs and calories, then Xwerks Grow isn’t the right choice. Instead, the company focuses on a maximum amount of high-quality protein, letting you get more carbs and calories through other dietary sources.

Each serving of Xwerks Grow contains 110 calories, 1g of carbs, and 25g of protein (from 27.8g of whey protein isolate). You also get vitamins, minerals, and other nutrients to support muscle growth and development.

Xwerks Motion


Xwerks Motion is the second Xwerks formula on our list. Motion is a synergistic blend of cluster dextrin carbohydrates, BCAAs, and electrolytes. Designed to boost energy with various short-term energy sources, Xwerks Motion is ideal for a pre-workout or intra-workout supplement while helping accelerate muscle development.

Xwerks motion contains 25g of carbs and 3g of BCAAs per serving. The formula is easy to digest with no bloating, and it mixes instantly into your formula. With 50 servings per bag, Xwerks Motion can help you push harder to the end of your workout – or accelerate recovery.

The critical ingredient in Xwerks Motion is cluster dextrin, also known as highly branched cyclic dextrin (HBCD). Developed in Japan, it’s a particular type of carb designed for rapid usage by your body. By combining Xwerks Motion with Xwerks Grow, you can create an effective mass gainer supplement stack.

D-Bal Max


D-Bal Max is a mass gainer that aims to replicate the effects of muscle-building steroids – but without the unpleasant side effects and legal concerns.

Described as “pure bodybuilding dynamite,” D-Bal Max aims to give you the raw power and insane gains you would get from Dianabol, one of the most popular and best-known steroids.

Featuring a blend of BCAAs, 20-hydroxy ecdysterone, and whey protein complex, D-Bal Max is designed to provide maximum mass gainer effectiveness with the added perk of steroid-like effects. Backed by a 60-day money-back guarantee, D-Bal Max could be the right choice for anyone seeking explosive performance.

Bulk Extreme


Bulk Extreme is one of the few mass gainers on our list found in a capsule – not a powder. Designed to help build muscle mass while supporting physical and mental performance, Bulk Extreme also claims to support testosterone optimization – something we don’t see with other mass gainers on our list.

Testosterone is crucial for muscle development. Studies show that men with higher testosterone levels can make larger muscles more rapidly than men with lower ones. Bulk Extreme claims to help using a blend of herbs and plants to optimize testosterone.

Key ingredients in Bulk Extreme include KSM-66, bitter melon extract (in the form of Momordicin), alfalfa herb extract, maca, saw palmetto, shilajit, and pumpkin seed extract. Many of these ingredients are found in other natural testosterone booster supplements, and Bulk Extreme contains significant doses of all components for maximum mass gainer – and testosterone boosting – effectiveness.


Gainful offers personalized supplements unique from any other company on our list. Designed by real experts (including Registered Dietitians), Gainful can build a customized protein powder, hydration formula, and pre-workout supplement based on your unique needs and physiology.

No two bodies are alike, so why are you taking the same mass gainer as someone else? With Gainful, you can create your mass gainer supplement (or let experts build it for you). If you want high protein levels and modest carbs, you can do that with Gainful.

You can also choose the type of protein you want in your formula – like plant-based sources, casein protein, or whey isolate, among other options.

You can create a Gainful mass gainer protein powder by taking the online quiz. Tell Gainful about your goals and diet, and fitness routine. Then, Gainful will create customized mass gainer formulas based on your unique needs. You can also chat for free with a registered dietitian to optimize your formula after release.

Optimum Nutrition Serious Mass


Optimum Nutrition Serious Mass is one of the best-selling supplements in the mass gainer space. It’s also one of the top-rated and best-value formulas.

Today, Serious Mass has an average rating of 4.5 stars out of 5 with 39,000+ reviews on Amazon, making it more popular than any other mass gainer supplement. With impressive macronutrient values and a dazzling list of ingredients, Serious Mass can help you gain muscle mass while providing substantial doses of vitamins, minerals, and other nutrients.

Serious Mass also has one of the largest serving sizes: you add two heaping scoops (336g) of formula to water or a shake, then drink it daily to gain mass. There are 16 servings per container.

Each serving of Serious Mass contains 1,250 calories, 253g of carbs, 50g of protein, and substantial doses of dozens of vitamins and minerals. If you want maximum macronutrient value, then Serious Mass could be the optimum choice.

MuscleTech Mass Tech Elite


MuscleTech Mass Tech is a muscle building mass gainer formula with 10g of creatine for optimal muscle development. While other mass gainers focus on hefty doses of protein, Mass Tech Elite uses a substantial amount of creatine to help build muscle mass further.

Mass Tech Elite also contains a ridiculous amount of protein and BCAAs. Each serving contains 80g of protein, 17g of BCAAs, and 1,000 calories for maximum mass gaining effectiveness (when mixed with two cups of skim milk).

MuscleTech is a trusted and well-known name in the bodybuilding supplement space, and Mass Tech Elite is one of the company’s most favored formulas. With some of the tastiest flavors and best mixability on our list, MuscleTech Mass Tech Elite can optimize your muscle development in multiple significant ways.

Naked Mass


Naked Mass uses just three premium ingredients to create a superior mass gainer formula. While other mass gainers dazzle you with dozens of components of all different types, Naked Mass uses just three ingredients in its unflavored formula and five ingredients in its chocolate and vanilla flavored formulas.

Each serving of Naked Mass contains 50g of protein, 11.5g of BCAAs, and 252g of complex carbs, along with 1,250 calories. Despite having just three ingredients, Naked Mass is one of the most potent options on our list.

You enjoy powerful effects with high-quality protein, whether taking Naked Mass before bed or after a workout. The three base ingredients in Naked Mass include organic tapioca maltodextrin, whey protein concentrate, and micellar casein.

BSN True-Mass Weight Gainer


BSN True-Mass Weight Gainer is a premium protein and carb matrix made by BSN, one of the more trusted names in the bodybuilding supplement space.

Available in unique flavors like a chocolate milkshake, cookies and cream, strawberry milkshake, and vanilla ice cream, BSN True-Mass Weight Gainer is a dominant and well-rated formula featuring 700 calories per serving.

BSN has crammed a lot of macronutrient value into a relatively small serving size. Each serving (3 rounded scoops) contains 165g of formula. That’s much higher than the average protein powder, but it’s smaller than competing mass gainers. Despite the smaller serving size, BSN True-Mass Weight Gainer contains 700 calories, 85g of carbs, and 50g (!) of protein.

We also like how BSN uses multiple types of protein with different absorption times, including whey protein concentrate, calcium caseinate, milk protein isolate, whey protein isolate, micellar casein, hydrolyzed whey protein, egg whites, and even glutamine peptides.

Labrada Muscle Mass Gainer


Labrada Muscle Mass Gainer is a value-packed mass gainer formula priced at just $35 per tub. Designed specifically for hard gainers, Labrada’s Muscle Mass Gainer contains 1,290 calories per serving (9 scoops / 341g per serving). You can also halve your serving size to enjoy powerful muscle building without the high amount of formula.

Each Labrada Muscle Mass Gainer serving contains 164g of carbs, 52g of protein, and vitamins and minerals to meet your needs.

However, Labrada uses more artificial ingredients than seen in higher-priced mass gainers. Each tub contains natural and artificial flavors and sucralose, for example. Although many mass gainer supplements use cheaper flavors due to high volume, some want to avoid these ingredients.

Labrada’s Muscle Mass Gainer could be the right choice if you don’t mind artificial ingredients and flavors and want a high-powered mass gainer at a discount price.

Dymatize Super Mass Gainer


Dymatize Super Mass Gainer is a high protein and carb blend from Dymatize, a top-rated bodybuilding supplement company.

Despite being one of the highest-quality mass gainer formulas on our list, Dymatize Super Mass Gainer is reasonably priced. You pay $45 per tub, with each tub containing around eight large servings (333g / 2.5 cups per serving).

Each serving of Super Mass Gainer contains 1,280 calories, 245g of carbs, and 52g of protein for maximum muscle development.

Dymatize is known for offering some of the best-tasting protein powders globally, and Super Mass Gainer is no exception. You can expect tasty flavors like cookies and cream, gourmet vanilla, and rich chocolate. However, be aware that Dymatize uses natural and artificial flavors and sucralose to create its delicious flavors.

MusclePharm Combat XL Mass Gainer


MusclePharm Combat XL Mass Gainer is a top-rated weight gainer protein powder featuring 1,270 calories, 252g of carbs, and 50g of protein per serving, making it competitive with other top-ranked protein powders on our list.

MusclePharm Combat XL Mass Gainer contains essential fatty acids, complex carbohydrates, and four protein sources to reach those macronutrient levels. It’s also banned substance tested and certified by Informed Choice, making it a more appealing choice to certain athletes.

If you want a high-quality mass gainer formula and trust the MusclePharm name, MusclePharm’s Combat XL Mass Gainer could be your right choice.

Rivalus Clean Gainer


Rivalus Clean Gainer describes itself as a “high protein lean gainer,” which means it emphasizes high levels of protein without overloading you with carbs and calories.

If you want serious muscle gaining power without feeling bloated or gaining too much weight, then Rivalus Clean Gainer could be the right choice.

Each serving (2 scoops / 130g) of Rivalus Clean Gainer contains 560 calories, 90g of carbs, and 30g of protein. Rivalus reaches these macronutrient values using a clean carbohydrate blend (with glucose polymers/maltodextrin, organic quinoa, and blueberry powder), a clean protein blend (with whey protein concentrate, whey protein isolate, micellar casein, and milk protein isolate), BCAAs, and natural and artificial flavors.

If you’re looking for a delicious lean mass gainer with premium dairy proteins, then Rivalus Clean Gainer could be the right choice.

How We Ranked The Top Mass Gainers

Every mass gainer supplement claims to provide substantial muscle gains with the highest quality protein.

However, we sifted through the marketing using the following ranking factors:

Mass Gainer Macronutrient Value

The best mass gainers provide high numbers of calories, protein, and carbs. You’re trying to gain mass and build muscle – not lose weight. If you’re serious about gaining mass, you want a mass gainer that provides the macronutrient intake you need.

Quality Ingredients Instead of Cheap Fillers

It’s easy to add calories and carbs to a supplement. Just add simple, cheap sugars and carbs. The best mass gainers use quality ingredients without cutting corners. We considered not just the macronutrient value of each mass gainer’s components but also the quality of the ingredients.

Limited Side Effects (Like Erratic Blood Sugar Spikes, Gas, and Bloating)

Any nutritional supplement company can add calories, carbs, and protein to a formula and call it a mass gainer. However, the best supplement companies take specific steps to limit side effects like erratic blood sugar spikes, gas, or bloating. If you’ve ever had a cheap mass gainer supplement, you know how uncomfortable these side effects can be. Good mass gainers pack on calories, carbs, and fat without making you feel gross.

Taste, Flavor, and Natural Ingredients

We preferred mass gainer supplements that used natural flavors and sweeteners. We also ranked mass gainers based on their taste. Some mass gainers have a sickly sweet flavor, while others taste naturally good.

Money-back or Satisfaction Guarantee

Reputable supplement companies stand behind their mass gainer supplements with money-back or satisfaction guarantees. We liked companies that stood behind their products with some promise. If you’re unsatisfied with the formula or did not gain significant muscle mass as advertised, you should be able to request a refund.

Digestive Enzymes

Some of the best mass gainers contain complementary ingredients like digestive enzymes to offset bloating. Digestive enzymes help your body break down specific elements, including carbs and protein, helping you get more protein without unpleasant digestive issues.

Other Complementary Ingredients

Some mass gainers also contain creatine to accelerate muscle growth. Creatine is one of the most popular and proven ways to boost the development of muscles. Others contain herbs, plants, and other ingredients to help build muscle mass. We considered these complementary ingredients in our rankings, assuming they were science-backed ingredients at potent dosages.

Protein Sources

Some mass gainer supplements use whey protein isolate. Others use a blend of multiple types of whey protein for maximum absorption, including protein your body absorbs short-term and long-term. We preferred mass gainers that used diverse, high-quality protein sources for maximum absorption and muscle building.

Honest Advertised Benefits

We were wary of mass gainer supplements that claimed to replicate the effects of anabolic steroids. We were also mindful of dishonest advertised benefits – like the ability to add 20lbs of muscle in a month. These claims aren’t realistic, and we preferred mass gainer supplement companies that were open and honest with their advertised benefits.

Carb to Protein Ratio

Most mass gainers aim for a 2:1 carbohydrate to protein ratio, ideal for gaining mass and muscle. We preferred mass gainer supplements at this ratio or closer to it.

Texture and Mixability

Texture and mixability are essential for all protein shakes, but they’re vital for mass gainers. Some mass gainers require you to mix 50g to 200g of powder (3 to 6 large scoops or more) of formula into a shaker cup. If your formula has a poor texture or isn’t very mixable, it can clump together and create a chalky texture. You don’t want that. We ranked mass gainers based on their consistency and mixability.

Manufacturer Reputation

Some top-ranked mass gainer supplement companies have made quality supplements for decades. Others are new to the scene. We preferred mass gainer supplement companies with a proven reputation for creating quality products. We also liked transparent manufacturers’ ingredient sources, manufacturing location, and contact information.

Ingredient Transparency

Mass gainers tend to have a large number of ingredients. Some manufacturers save time by bundling all components into a proprietary formula, making it tough to view individual dosages. Others take the time to disclose each dose for maximum transparency. The more ingredient transparency a supplement had, the higher we ranked it.

Doctor or Dietitian Formulated

Medical doctors (MDs) and registered dietitians (RDs) formulate the best mass gainers. Some supplement companies have a medical advisory board, while others do not. The more professional certification went into creating a mass gainer supplement, the higher we ranked it.

How Do Mass Gainers Work?

Mass gainers provide your body with the ingredients to add lean muscle mass. A good mass gainer contains high protein, carbs, and fat levels to aid muscle development.

Mass gainers are like high-powered protein powders with added fats, calories, and carbs.

An average protein powder gives you the highest protein without overloading you with carbs and calories.

Meanwhile, a meal replacement protein shake may have more calories, fats, vitamins, and minerals than a protein powder, but it’s not as hefty as a mass gainer.

Finally, a mass gainer protein powder provides high levels of everything to help you gain weight, pack on lean muscle mass, and support your body while following a strenuous workout program.

If you want to gain as much lean mass as possible as quickly as possible, then a mass gainer supplement is the best option.

What Does a Mass Gainer Do?

A good mass gainer should:

  • Help build lean muscle mass
  • Help you meet extra calorie requirements
  • Contain specially-built carbs and proteins, including multiple protein sources with different absorption times
  • Contain vitamins, minerals, healthy fats, and other ingredients to support an active exercise routine
  • Contain fibers, digestive enzymes, and other digestion-boosting ingredients to reduce bloating and boost absorption

Mass gainers are not the same as weight gainers. Mass gainers are designed to boost lean muscle mass, while weight gainers are designed to gain weight, regardless of muscle mass.

You can boost the effects of a mass gainer further by mixing it with milk. Many mass gainer manufacturers recommend mixing the formula with skim milk, for example, to boost calorie and protein intake.

Who Should Take a Mass Gainer Supplement?

People take mass gainers for a variety of reasons. Some of the reasons to take a mass gainer supplement include:

  • Anyone Wanting to Add Lean Muscle: Mass gainers are popular because you can add lean muscle without gaining fat. A mass gainer could be the right choice if you want to add lean muscle and bulk up without feeling bloated.
  • Skinny People: Some people are slim no matter what they eat. You might have an overactive metabolism, for example. Many young people struggle to add lean muscle and bulk up. If you’re a skinny person working on adding lean muscle, then a mass gainer could be the right choice.
  • Someone Who Struggles to Add Muscle or Gain Weight: Some people struggle to add muscle and gain weight. They may have medical issues, a strong metabolism, or other characteristics that make it hard to add muscle and weight.
  • Anyone With an Imperfect Diet: If you’re exercising regularly, you need an excellent diet to repair your body. If you don’t have a perfect diet, you may feel sluggish, and your muscle development could suffer. A mass gainer can help fill nutritional holes, supplementing your diet to support your active routine.
  • Anyone Who Works Out Heavily: Even if you’re not trying to add muscle mass, a mass gainer supplement could be the right choice to support your active training or workout routine.

Pros and Cons of Mass Gainers

Mass gainer supplements are associated with a range of different benefits. It’s no secret that mass gainers can boost muscle mass and weight gain. However, many are surprised that mass gainers can help with insulin levels, lean muscle development, and other effects.

Here are some of the pros and cons of mass gainer supplements.


Thousands use mass gainers daily for different benefits. Some of the benefits of a good mass gainer include:

  • Gain lean muscle quickly without adding fat
  • Repair muscles after intense workouts
  • Give your body the healthy fats, BCAAs, proteins, carbs, and calories it needs to fuel an active lifestyle.
  • Get on-the-go nutrition when you don’t have time to cook big meals
  • Maximize muscle development and pack significant lean muscle onto your body


There aren’t many downsides of mass gainers. When used correctly, they’re a powerful and effective supplement. However, some cons to consider include:

It’s easy to go overboard. Some people take a mass gainer supplement daily, for example, without exercising enough. You might think you’re working out a lot. But if you’re not working out correctly and burning many calories with every workout, you could go overboard with a mass gainer and gain weight.

They’re not an instant solution. Mass gainers are like protein powders: they don’t work overnight; instead, they play a crucial role in a healthy diet and exercise routine by helping you gain muscle mass over time. If you’re expecting an instant solution to your weight loss problems, mass gainer supplements may not be the right choice.

Cheaper mass gainers may have weird ingredients. It’s not hard to add calories and carbs to a formula. Some cheap mass gainer supplement companies add weird ingredients – like cheap sugars and carb sources. You might as well eat a scoop of instant potato mix. Watch for more affordable mass gainer supplements and be wary of cheap ingredients. In many cases, you’re better off buying a higher-end mass gainer.

Mass Gainer Side Effects

Mass gainers could lead to bloating, upset stomach, weight gain, and other side effects. However, when taking a good mass gainer and following the recommended instructions, you should be able to limit mass gainer side effects.

Some side effects associated with mass gainer supplements include:

  • Upset stomach
  • Bloating and cramping
  • Digestive issues
  • Flatulence
  • Allergic reactions (if you’re dairy or lactose intolerant)
  • Weight gain (especially if you aren’t exercising regularly while taking the mass gainer)

Your chance of experiencing mass gainer side effects increase when taking lower-quality formulas. You can find plenty of mass gainer supplements with different prices and ingredients. If you’re buying a budget mass gainer, you might discover artificial ingredients, cheap ingredients, and other ingredients that increase the chances of experiencing all the side effects listed above.

How to Avoid Mass Gainer Stomach Aches

Mass gainers contain as much as 50g of protein per serving. Even 20g to 30g of protein is enough to give you significant stomach pains and bloating.

Fortunately, there are ways to prevent mass gainer-related stomach aches. Here are some tips:

Buy a Better Mass Gainer

Some of the best-rated mass gainers contain digestive enzymes like proteases that help your body digest protein. If your gut doesn’t have proteases, you’ll struggle to process protein. A good mass gainer contains digestive enzymes, higher-quality proteins, and blends of proteins with different digestion times to maximize absorption and minimize stomach pain.

Take a Half or Quarter Serving Size

Some mass gainers have enormous serving sizes (250g to 350g of powder per serving). Consider taking a half or quarter dose to let your body adjust.

Drink More Water

Your body needs water to process everything you consume. However, drinking water is essential when taking protein, creatine, and other ingredients in mass gainers. Water helps push everything through your digestive tract more efficiently. Drink more water if you’re experiencing bloating and constipation from mass gainers.

Use a Blender Bottle or Mixer

You can mix an average protein shake with a few good shakes of your bottle. Mass gainers, however, require more mixing and effort. Use a blender bottle or a powered mixer to make your mass gainer supplement. It breaks up the active ingredients, making them easier for your body to process.

Drink a Mass Gainer Over 1 Hour

Instead of drinking your mass gainer all at once, drink it for over an hour. Start drinking your mass gainer towards the end of your workout, for example, and finish it after your workout. Instead of giving your body 50g of protein in 3 minutes, you’re giving your body a more gradual dosage of protein.

Scientific Evidence for Mass Gainers

There are plenty of studies on protein powders. However, there are few studies specifically on mass gainers. We’ll review evidence below on protein powders, muscle mass, and strength gains to determine if mass gainers work – or if it’s all just junk science.

In this 2015 study, researchers analyzed the effects of protein supplements on muscle mass, strength, and aerobic and anaerobic power. Researchers analyzed dozens of studies on protein powders. After this analysis, researchers concluded that protein supplementation might enhance muscle mass and performance when paired with a good training routine and following an active diet. In other words, protein supplements can help develop lean muscle mass in physically active individuals.

Similarly, this 2018 study analyzed the effects of protein supplementation on performance and recovery when following an active training routine. Researchers gave participants protein powder or a placebo after a workout, then measured the effects. Researchers found dietary intake was more critical for boosting muscle mass and development after a workout. However, protein powders could help fill those holes in individuals with a less-than-perfect diet.

Many of the best mass gainers contain branched-chain amino acids (BCAAs). Studies show BCAAs are crucial for muscle mass and muscle development. In this 2017 study, for example, researchers found BCAA supplementation reduced protein breakdown after a workout and boosted protein synthesis. In other words, your body might lose muscle mass after a workout if you’re not taking a BCAA supplement (or getting BCAAs from your diet).

Many people feel bloated after taking a mass gainer – and that’s okay. Mass gainers contain high protein levels, and protein can lead to bloating. Many mass gainers contain proteolytic enzymes (also known as proteases, peptidases, and proteinases). Your body uses these digestive enzymes to break down the protein into a usable form for your body. If you’re struggling with bloating and other digestive issues after taking a mass gainer, consider picking a mass gainer with proteases.

Overall, the best mass gainers use science-backed ingredients to help you gain lean muscle mass without getting fat. If you want to maximize muscle gain while following a healthy workout program, then a good mass gainer supplement can help.
