Gaining weight sounds simple on paper:
Eat more calories than you burn.
In practice, consistently eating enough food can be one of the hardest parts of building muscle — especially for people with high activity levels, demanding training schedules, smaller appetites or naturally lower body weight.
That’s where mass gainers can help.
A mass gainer is a high-calorie nutrition powder that typically combines protein and carbohydrates, often with additional fats, vitamins, minerals or performance ingredients.
Instead of forcing down another full meal, a mass-gainer shake can add anywhere from a few hundred to more than 1,000 calories to your day.
But bigger isn’t automatically better.
Some products provide approximately 250 calories per scoop and let you gradually increase your intake. Others provide more than 1,200 calories in one manufacturer-defined serving.
Choosing the right product therefore depends less on finding the biggest calorie number and more on determining how many additional calories you actually need.
A review of intentional weight-gain recommendations for athletes notes that sports-nutrition guidance commonly starts with an additional 300–500 calories per day, together with adequate protein, carbohydrates and resistance training.
That is important because gaining body weight faster does not necessarily mean building muscle faster.
The best mass gainer is therefore the product that helps you consistently reach an appropriate calorie and protein target without pushing your surplus unnecessarily high.

Best Mass Gainers in Canada
1. MUTANT Mass — Best Overall
MUTANT Mass takes our best overall position because it delivers serious calorie density without relying on a single protein or carbohydrate source.
A full serving provides approximately 1,100 calories and 56 grams of protein.
The protein comes from six sources, including whey protein concentrate, hydrolyzed whey, whey isolate, micellar casein, milk protein concentrate and milk protein isolate.
MUTANT also incorporates carbohydrate and fat ingredients such as rolled oats, barley, sweet potato, avocado, coconut and seeds alongside more conventional mass-gainer ingredients.
That makes it particularly useful for someone who wants a genuinely calorie-dense shake but still values some variety in the macronutrient sources.
The key is not assuming you must take the entire serving.
If you only need roughly 500 additional calories, a partial serving may fit your diet much better than consuming all 1,100 calories at once.
Why We Like It: A large calorie load, 56 grams of protein from multiple sources and enough serving flexibility to scale the shake according to your needs.
Best For: Lifters who genuinely struggle to consume enough calories and want an all-around bulking product.
Possible Downside: A full 1,100-calorie serving can create an unnecessarily large calorie surplus for many users.
Chrisima Verdict: Our best overall choice. Start below the maximum serving and increase only if your body-weight trend shows that you need more calories.
2. Mammoth Mass — Best for Hard Gainers
Mammoth Mass is designed for people who have a genuinely difficult time consuming enough food to gain weight.
The current Canadian nutrition information lists approximately 1,250 calories, 60 grams of protein and 230 grams of carbohydrates per four-scoop serving mixed with water. The same serving contains only about 9 grams of sugar.
Mammoth also incorporates carbohydrate ingredients such as quinoa, sweet potato and rolled oats alongside MCTs.
For someone with a physically demanding lifestyle, very high training volume or low appetite, that calorie density can be useful.
For someone who only needs an extra 300 calories per day, it is probably excessive.
Why We Like It: Very high calorie density, 60 grams of protein and relatively little sugar compared with the enormous total carbohydrate load.
Best For: Serious hard gainers and people with unusually high calorie requirements.
Possible Downside: A 1,250-calorie shake can easily turn a controlled bulk into an unnecessarily aggressive one.
Chrisima Verdict: One of the strongest high-calorie Canadian options, but splitting the serving into two smaller shakes will make more sense for many users.
3. PVL Clean Mass XL — Best Clean Mass Gainer
PVL Clean Mass XL approaches weight gain differently from the classic “maximum calories at any cost” strategy.
PVL currently describes the formula as providing 1,120 calories and 60 grams of protein across two daily servings, using 25 food-derived ingredients.
Protein sources include whey, milk, fermented pea and pumpkin seed.
Carbohydrate sources include fermented pea starch, quinoa, brown rice and sweet potato, while the fat blend includes ingredients such as MCTs, avocado and flax.
This does not magically make calories “clean” or eliminate the possibility of fat gain.
What it does give you is a more diverse ingredient profile than many traditional mass gainers based heavily around maltodextrin.
Why We Like It: Diverse protein, carbohydrate and fat sources with a formulation aimed at controlled bulking rather than simply maximizing calories per scoop.
Best For: People who want additional calories while placing more emphasis on ingredient quality and a gradual bulk.
Possible Downside: Premium ingredients generally make products like this more expensive than basic carbohydrate-heavy gainers.
Chrisima Verdict: Our preferred option for a cleaner, more controlled bulk and a natural cornerstone for our future Clean & Lean Mass Gainers category.
4. ALLMAX QuickMass — Best for Flexible Dosing
ALLMAX QuickMass solves one of the biggest problems with mass gainers:
Oversized servings.
The current Canadian nutrition panel provides approximately 250 calories, 16 grams of protein and 43 grams of carbohydrates per scoop.
Four scoops provide approximately 1,010 calories, 64 grams of protein and 172 grams of carbohydrates.
That makes QuickMass exceptionally easy to adjust.
If you need approximately 250 extra calories, take one scoop.
If you need around 500, use two.
Only someone with a much larger calorie requirement needs to move toward the full four-scoop serving.
QuickMass also uses carbohydrate ingredients including maltodextrin, sweet potato, quinoa and oat fibre.
Why We Like It: Extremely easy calorie scaling and a full serving containing 64 grams of protein.
Best For: Beginners and anyone who wants tight control over how much additional energy their mass gainer contributes.
Possible Downside: The impressive 64-gram protein number applies to the entire four-scoop serving. One scoop provides 16 grams.
Chrisima Verdict: One of the smartest products for someone new to mass gainers because you can increase calories gradually instead of jumping immediately to 1,000.
5. Dymatize Super Mass Gainer — Best Maximum-Calorie Option
Dymatize Super Mass Gainer is designed for people who need an enormous amount of additional energy.
Depending on flavour, the current formula provides up to approximately 1,310 calories, 52 grams of protein and 252 grams of carbohydrates per serving.
The Rich Chocolate version, for example, currently lists 1,280 calories, 52 grams of protein and 245 grams of carbohydrates per serving.
View Dymatize Super Mass Gainer
Its protein blend includes whey and milk-derived proteins with both faster- and slower-digesting characteristics.
The formula also includes creatine monohydrate along with vitamins and minerals, and Dymatize identifies the product as banned-substance tested.
The calorie number is impressive.
But impressive does not automatically mean appropriate.
Someone who only needs 400 additional calories should not consume 1,300 merely because that is the manufacturer’s full serving.
Why We Like It: Extremely high calorie density, 52 grams of protein and a broad protein blend.
Best For: Highly active hard gainers with genuinely large calorie requirements.
Possible Downside: More than 1,200 calories and roughly 250 grams of carbohydrates in one serving can dramatically overshoot the needs of an average recreational lifter.
Chrisima Verdict: A powerful tool for genuine hard gainers, but excessive for many people trying to build muscle gradually.
6. PERFECT Sports HULK — Best Canadian Controlled-Bulk Option
PERFECT Sports HULK is another product that makes controlling the calorie surplus easy.
One scoop currently provides approximately 260 calories, 12.5 grams of whey protein, 42 grams of carbohydrates and 3 grams of fat.
The formulation also contains concentrated fruit and vegetable ingredients.
PERFECT Sports identifies HULK as independently tested for sport and Informed Choice certified.
That makes it particularly interesting for competitive Canadian athletes.
Like QuickMass, HULK allows you to build your calorie intake one scoop at a time instead of automatically consuming an enormous shake.
Why We Like It: Flexible calorie dosing, Canadian availability and credible banned-substance testing.
Best For: Canadian athletes and anyone wanting a more controlled calorie surplus.
Possible Downside: Protein per individual scoop is relatively modest compared with a dedicated whey protein serving.
Chrisima Verdict: A strong option for controlled bulking and one of the most practical products for people who don’t need 1,000 calories every time they make a shake.
What Is a Mass Gainer?
A mass gainer is a high-calorie powdered nutrition product designed to make increasing calorie intake easier.
Most combine three basic macronutrients:
Protein supports muscle repair and growth.
Carbohydrates supply most of the calories in many weight-gain formulas and help support demanding training.
Fat may be added because it provides a highly concentrated source of calories.
Mass gainers can therefore range from relatively moderate products providing a few hundred calories to enormous formulas supplying well over 1,000 calories per serving.
Some also contain creatine, amino acids, vitamins, minerals, digestive enzymes or other ingredients.
The defining characteristic is not a particular ingredient.
It is calorie density.
Mass Gainer vs Weight Gainer: Is There a Difference?
There is no standardized nutritional distinction between a “mass gainer” and a “weight gainer.”
The terms are generally used interchangeably.
“Mass gainer” tends to sound more appealing to bodybuilding audiences because the goal is usually muscle mass rather than simply seeing the scale increase.
But the powder itself cannot determine whether the weight you gain becomes muscle or body fat.
That depends on factors including:
Resistance training.
Protein intake.
Calorie surplus.
Training experience.
Recovery.
Genetics.
Rate of weight gain.
This is why Chrisima treats Mass & Weight Gain as one category, rather than building separate Mass Gainer and Weight Gainer silos that would compete for almost identical searches.
Do Mass Gainers Actually Build Muscle?
A mass gainer does not independently create muscle tissue.
It solves a different problem:
insufficient nutrition.
Resistance training provides the primary stimulus for muscle growth.
Protein supplies essential amino acids.
Calories provide the energy required to support training, recovery and tissue growth.
The NIH Office of Dietary Supplements guide to exercise and athletic-performance supplements emphasizes that adequate calories, carbohydrates, protein, fat, fluids and micronutrients form the nutritional foundation for athletic performance.
Protein is particularly important.
The International Society of Sports Nutrition position stand on protein and exercise states that approximately 1.4–2.0 grams of protein per kilogram of body weight per day is sufficient for most exercising individuals seeking to build or maintain muscle.
A mass gainer can help you reach those requirements when ordinary meals aren’t enough.
That’s very different from saying that drinking a mass gainer automatically produces muscle.
Without an appropriate resistance-training stimulus, a large calorie surplus can simply increase body weight.
How Many Extra Calories Do You Need to Gain Muscle?
You probably need far fewer additional calories than the front of many mass-gainer bags suggests.
A critical review of weight-gain recommendations for athletes reports that commonly recommended strategies start around 300–500 additional calories per day, alongside resistance training and sufficient protein and carbohydrate intake.
That doesn’t mean everybody needs exactly 400 calories.
It gives you a sensible starting framework.
Your actual calorie needs depend on body size, training volume, activity level and current intake.
A practical strategy is to determine roughly how much you’re currently eating, introduce a moderate calorie surplus, monitor your body-weight trend and adjust from there.
That approach is far more useful than automatically taking four scoops because four scoops happen to be called “one serving.”
How Fast Should You Gain Weight?
For muscle-focused bulking, faster is not necessarily better.
A commonly cited evidence-based bodybuilding approach is to aim for approximately 0.25–0.5% of body weight per week for novice and intermediate trainees, with experienced lifters often benefiting from an even more conservative approach.
You can review those recommendations in this evidence-based review of bodybuilding nutrition.
For someone weighing 80 kg, a 0.25–0.5% weekly rate would equal approximately 0.2–0.4 kg.
Daily scale weight will fluctuate because of:
Water.
Food volume.
Carbohydrate intake.
Sodium.
Glycogen.
Bowel contents.
For that reason, monitor the weekly average rather than panicking over individual weigh-ins.
What Should You Look for in a Mass Gainer?
Calories That Match Your Needs
This should be your first filter.
If you’re currently maintaining your weight and only need another 300 calories, buying a 1,300-calorie gainer doesn’t mean you have to use its entire serving.
Products with flexible scoop sizes can be especially useful.
Adequate Protein
Protein is essential for muscle-building diets.
The ISSN protein position stand places a useful general range for exercising adults around 1.4–2.0 g/kg/day.
How much protein you need from your mass gainer depends on how much you’re already getting from food.
Carbohydrate Sources
Carbohydrates are not inherently a negative feature in mass gainers.
In fact, high carbohydrate content is often exactly how a gainer provides enough energy to help someone increase body weight.
Products vary substantially, though.
Some rely heavily on maltodextrin.
Others incorporate oats, rice, quinoa, sweet potato, pea starch or several carbohydrate sources.
Know what you’re buying rather than assuming every carbohydrate is identical.
Fat Content
Fat contains approximately nine calories per gram, making it an efficient way to increase calorie density.
Some gainers therefore incorporate ingredients such as MCT oil, coconut, avocado, flax or other fats.
Sugar
Sugar content is useful to examine, but don’t use it as the only measure of quality.
Compare it with total carbohydrate, overall calories and the entire ingredient profile.
Serving Flexibility
This is one of the most underrated criteria.
A product providing 250 calories per scoop gives you much more control than a formula that is difficult to divide into realistic portions.
High-Calorie vs Clean Mass Gainers
These represent two distinct buying intents, which is why we will eventually treat them as their own Chrisima subcategories.
A high-calorie mass gainer prioritizes getting as much energy as possible into a convenient shake.
Products such as Mammoth Mass and Dymatize Super Mass Gainer fit this role.
A clean or lean mass gainer generally emphasizes more controlled calories, diverse carbohydrate sources, lower sugar positioning and a broader food-derived ingredient profile.
PVL Clean Mass XL and PERFECT Sports HULK fit more naturally here.
Neither category is automatically better.
A highly active person struggling to consume 4,000 calories may benefit considerably from an extremely calorie-dense gainer.
Someone needing only another 300 calories probably doesn’t.
What Is a Hard Gainer?
“Hard gainer” is a fitness term rather than a medical diagnosis.
It usually describes someone who struggles to increase body weight despite believing they eat a lot.
There are many possible explanations.
Some people have high physical activity levels.
Some have physically demanding jobs.
Others have low appetite or become full quickly.
Some naturally move frequently throughout the day.
And many people simply underestimate their energy expenditure or overestimate their calorie intake.
This is where liquid calories can be particularly useful.
The athlete weight-gain review specifically identifies strategies such as energy-dense foods, larger portions and liquid calories as practical methods for increasing total intake.
Mass gainers are essentially a convenient commercial version of that strategy.
Should Beginners Use Mass Gainers?
They can.
You don’t need years of bodybuilding experience before calories and protein start mattering.
But beginners should be especially careful about blindly using the full serving.
If someone only needs approximately 300 additional calories, starting with 1,200 additional calories is unnecessary.
A more sensible approach is to begin with a smaller amount, track the scale trend for a couple of weeks and adjust.
Products such as QuickMass and HULK work particularly well for this because you can add one scoop at a time.
Mass Gainer vs Whey Protein
These supplements solve different problems.
Whey protein is primarily designed to help increase protein intake.
Mass gainer is primarily designed to help increase total calorie intake, while also contributing protein.
A typical whey shake may provide approximately 20–30 grams of protein for relatively few calories.
A mass gainer can contain hundreds or more than 1,000 calories.
So if you’re already eating enough calories but struggle to consume enough protein, whey is usually the more logical choice.
If you’re getting enough protein but can’t reach your calorie requirement, mass gainer may solve the bigger problem.
If you’re short on both, a gainer can address both simultaneously.
Mass Gainer vs a Homemade Weight-Gain Shake
You do not need commercial mass gainer powder to gain weight.
A homemade shake can easily combine whey protein with ingredients such as oats, milk, banana, peanut or almond butter and fruit.
Depending on portions, a homemade shake can provide 500–1,000 calories without using a dedicated gainer.
The advantage is ingredient control.
You decide exactly how much protein, carbohydrate and fat goes into the shake.
The disadvantage is convenience.
A commercial powder can be measured into a shaker in seconds.
A homemade shake usually involves several ingredients, refrigeration and often a blender.
Neither approach is universally superior.
When Is the Best Time to Take a Mass Gainer?
There is no magical mass-gainer timing window.
The primary purpose is helping you reach your daily calorie and protein targets.
Useful times can include between meals, after training, during a busy workday or whenever eating another solid meal is difficult.
The NIH sports-supplement guidance emphasizes the broader importance of sufficient daily energy and macronutrient intake for athletic performance rather than treating one supplement timing window as the foundation of progress.
Post-workout is convenient.
It is not mandatory.
Should You Take Mass Gainer Before or After Training?
Both are possible, but serving size matters.
Drinking 1,200 calories immediately before heavy squats may produce an unpleasant training session.
A smaller shake before exercise may be completely fine.
Large servings generally make more practical sense after training or between meals.
Your digestive comfort matters more than following a marketing rule.
Milk or Water?
Water keeps the calorie total closest to what appears on the product label.
Milk adds additional calories, protein and carbohydrates.
That can be useful for a serious hard gainer.
It can also accidentally turn an already enormous shake into a calorie bomb.
For example, a 1,200-calorie gainer mixed with several cups of milk can easily become a much larger meal than the user realizes.
Calculate the complete shake, not just the powder.
Can Mass Gainers Make You Fat?
Yes.
Any sustained calorie surplus can contribute to body-fat gain.
Mass gainers simply make it easier to create that surplus because they’re extremely calorie-dense.
The goal during a muscle-building phase should therefore not be:
gain as much weight as possible.
It should be:
consume enough additional energy to support training and gradual weight gain without unnecessarily accelerating fat accumulation.
This is another reason the 300–500-calorie starting range discussed in the athlete weight-gain literature is more useful than automatically consuming a manufacturer’s maximum serving.
Are Mass Gainers Safe?
For most healthy adults, mass gainers are primarily concentrated sources of familiar nutrients such as protein, carbohydrate and fat.
But formulas can also contain creatine, vitamins, minerals, botanical ingredients, sweeteners and allergens.
That means you should read the complete label.
Canadian consumers can also use the official Health Canada Licensed Natural Health Products Database to search licensed natural health products and review their current licence information.
People with diabetes, kidney disease, digestive disorders, food allergies or other medical conditions should discuss major dietary or supplement changes with an appropriate healthcare professional.
Do Mass Gainers Contain Creatine?
Some do.
Others do not.
Check the ingredient label rather than assuming.
Dymatize Super Mass Gainer, for example, currently lists creatine monohydrate among its ingredients.
If your gainer already contains creatine and you’re also taking a separate creatine supplement, account for your total intake.
For a detailed comparison of creatine products, see our Best Creatine Supplements in Canada for Muscle Growth and Strength guide.
Do You Need Mass Gainer and Creatine Together?
You don’t need either supplement.
But they perform different jobs.
Mass gainer primarily helps increase calories, protein and other macronutrients.
Creatine helps increase muscular creatine availability and can improve repeated high-intensity exercise capacity.
The NIH exercise-performance supplement guide notes that creatine can increase strength, power and work performed during maximal muscular efforts and identifies creatine monohydrate as the most widely studied form.
Someone trying to gain muscle may therefore reasonably use both when appropriate.
Can Women Use Mass Gainers?
Yes.
Calories and protein are not male-specific.
A woman trying to build muscle or increase body weight may use a mass gainer if consuming enough food is difficult.
The serving size should simply match her individual energy requirements.
That principle applies to everyone.
Use your calorie requirement — not gendered supplement marketing — to determine the serving.
Are Mass Gainers Good for Skinny People?
They can be extremely useful for someone who genuinely struggles to eat enough calories.
Liquid calories can make increasing energy intake easier because drinking calories may feel less filling than consuming another large solid meal.
But the goal should still be gradual, structured weight gain.
Being naturally thin does not mean the smartest strategy is immediately adding 1,500 calories per day.
Start with the amount required to create progress.
How to Use a Mass Gainer Without Gaining Too Much Fat
The simplest approach is to start below the maximum serving.
Track your morning body weight under similar conditions and focus on your weekly average.
If the average is not increasing after sufficient time, add calories.
If it is increasing much faster than intended, reduce them.
Continue resistance training and maintain adequate daily protein.
And keep most of your overall diet based on nutrient-dense foods.
A mass gainer should fill nutritional gaps.
It should not become your entire diet.
Who Should Consider a Mass Gainer?
A mass gainer becomes especially useful when insufficient calorie intake is the actual problem.
That commonly includes people with low appetite, very high daily activity, intense training schedules, physically demanding jobs, difficulty preparing enough meals or deliberate muscle-building goals that require more calories than they comfortably consume.
Who Probably Doesn’t Need One?
If you’re already gaining weight at an appropriate rate, adding a mass gainer provides little benefit.
Likewise, if your only problem is insufficient protein, a normal protein supplement may be much more efficient.
Someone actively trying to reduce body fat also generally does not need a product designed specifically to make consuming extra calories easier.
How to Choose the Best Mass Gainer in Canada
Start by estimating the size of your calorie gap.
Then check calories per scoop, not only the giant serving printed on the front of the bag.
Look at the amount of protein, the carbohydrate sources, fat content, sugar and the complete ingredient panel.
Consider whether the serving can be scaled easily.
Competitive athletes should also pay attention to meaningful third-party banned-substance testing.
Finally, calculate the cost according to the portion you will actually use, not necessarily the manufacturer’s maximum serving.
Canadian shoppers can verify applicable licensed products using the official Health Canada Licensed Natural Health Products Database.

Final Thoughts
The best mass gainers in Canada for muscle growth and weight gain aren’t necessarily the products with the largest calorie numbers.
The right product is the one that fills the calorie gap in your diet without pushing your surplus unnecessarily high.
MUTANT Mass is our best overall option because it combines approximately 1,100 calories with 56 grams of protein and multiple macronutrient sources.
Mammoth Mass is particularly useful for true hard gainers who need an exceptionally calorie-dense shake.
PVL Clean Mass XL is our preferred cleaner-bulking option.
ALLMAX QuickMass stands out for extremely flexible 250-calorie-per-scoop dosing.
Dymatize Super Mass Gainer provides one of the largest calorie servings for people with very high energy requirements.
And PERFECT Sports HULK offers another flexible Canadian option with meaningful sport-testing credentials.
The principle that matters most is simple:
Don’t let the serving size printed on the bag determine your calorie surplus.
Start with your actual nutritional requirements.
Use the gainer to fill the difference.
Combine an appropriate calorie surplus with progressive resistance training, enough protein and sufficient recovery.
That’s when a mass gainer becomes a useful muscle-building nutrition tool rather than simply an easy way to consume excessive calories.
