Mass Gainer Buying Guide
Mass gainer supplements are high-calorie, high-protein, high-carbohydrate meal replacements that are meant to help you pack on weight fast!
Thanks to their nutritional density and often pleasant taste, they’re a godsend for those who have small appetites and fast metabolisms (sometimes referred to as “hard gainers”). They’re convenient and help to save you time and headaches, particularly if you lead a very busy lifestyle.
However, there’s a catch!
Many of the mass gainers on the market today are full of low-quality fillers, additives, and cheap carbohydrates just so that they can fill the container as well as line their pockets. But no worries, we’re here to help you rummage through the B.S. and get to the good, high-quality stuff.
We’ll tell you what to look for in a mass gainer supplement so that next time you’re in the market for one, you’ll know just what to look for.
Qualities of a Good Mass Gainer
Value
Does the mass gainer you’re considering contain high-quality ingredients that will help you pack on clean weight primarily composed of muscle? Or is it filled with cheap crap that’s marked up extremely high?
Also, how does the price of the mass gainer supplement compare to others on the market? If it lies in the extremely low range, it’s most likely composed of low-quality, cheap filler ingredients, additives, and preservatives.
If it’s very expensive, it better have high-quality ingredients you’ll find here in this guide, or else it’s definitely not worth your money.
Servings Per Container
Servings in mass gainer supplements are often very big. What I mean by that is the scoop size itself is very large in order to accommodate all of the macronutrients and calories that are in the supplement.
So usually mass gainers will come in very large bags or plastic tubs. Even though this is the case, it’s still important to look at the supplement facts label to see what the serving size is exactly (in grams) and how many calories and macronutrients are contained within each serving.
I bring this up because sometimes companies will state that the product has an enormous amount of calories in a statement on the front of the packaging, but if you look in tiny little letters next to an asterisk, it states that it contains that many calories in two scoops, which just happens to be 2 servings, not one.
This is of course just an example, but it’s, unfortunately, more common than one might think. Therefore, it’s imperative that you be on the lookout for marketing tactics such as this that try to mislead you.
Also, a serving of a mass gainer is often multiple scoops-worth, not just one. So make sure to properly read the nutritional label before taking the mass gainer.
User Feedback
Have your friends heard of the product? Have you looked it up online? Oftentimes, looking at product reviews that aren’t on the manufacturer’s own website (i.e. Amazon, Bodybuilding.com) will give you a pretty good idea of the quality of the product.
Brand Reputation
Have you heard of other supplements from this brand before? Maybe you’ve tried them yourself with a different product of theirs? Give them a look up on TrustPilot or Better Business Bureau to ensure that the company you plan on doing business with deserves your money and hasn’t been doing anything sketchy.
Things to Consider when Buying a Mass Gainer
Macros
What is the total macronutrient profile of the mass gainer you’re looking to purchase? Although there are no hard and fast numbers to abide by and look for, we’ll provide you with some general guidelines so that you can sniff out the good stuff from the bad.
You want to make sure that the mass gainer has a sufficient amount of protein compared to the carbohydrate content it has. While carbohydrates can certainly help to build muscle, they are the cheapest of ingredients (whether low or high-quality) compared to proteins and fats (particularly if they are of high quality).
Because of this, sometimes companies will skew the ratio of carbs to fats way too much in the favor of carbs since it is much cheaper to do so.
When looking for an optimal macronutrient ratio of a mass gainer, there are a few figures that you should consider, depending on how much weight you’re looking to gain from taking this supplement.
| Weight Gain Goal | Carbohydrate:Protein Ratio |
| 0.5 lbs/week | 2:1 |
| 1 lb/week | between 2.5:1 to 3.5:1 |
| 1.5 lbs/week | between 3:1-4.5:1 |
Calories
You’ll see mass gainers that vary widely in calories. Some will be as low as 600 calories per serving while others will be over 2000 calories per serving. It’s really up to the manufacturer to decide how many calories go into a serving of their mass gainer supplement.
So it’s up to you to decide how many calories you need to supplement with in order to reach your calorie goals that support your muscle-building efforts.
Just make sure not to let the mass gainer comprise the bulk (no pun intended) of your diet. Remember, this is a supplement, not a crutch. Make sure your diet consists primarily of whole foods that are minimally processed and then use the mass gainer supplement when you need it most, such as when you’re on a time crunch.
Ingredient Quality
As we’ve stated earlier in this guide, you have to make sure that in order to get the most value for your money, that the mass gainer supplement you decide to purchase has high-quality sources of protein, carbohydrates, and fats.
While the following list isn’t meant to be exhaustive, it’ll give you a good reference to look back to if you ever get stuck when you’re looking at the nutritional label of a mass gainer supplement.
| High-Quality Protein Sources | High-Quality Carbohydrate Sources | High-Quality Fat Sources |
| whey isolate and/or hydrolysate | oats | medium chain triglycerides |
| egg/albumin | sweet potato | any type of nut butter |
| beef | bran | flax |
| casein | quinoa | hemp |
| pea | buckwheat | egg yolk |
| brown rice | tapioca | chia |
| hemp | any fruit-based source | coconut oil |
You want to avoid mass gainers that have “maltodextrin” as one of the first ingredients on the ingredients list. This is because maltodextrin is a simple sugar that companies often use as a filler to make up a significantly large portion of the carbohydrate content.
You want a majority of the carbohydrate sources to be from whole food sources so that you have a nice, gradual, steady energy throughout the day, rather than getting a “sugar high” essentially and coming way up and then crashing down rapidly. Not a good time, trust us. Plus, it won’t do you any good for your performance or body composition either.
Protein Type & Quality
You want to make sure that the type of protein being included is high-quality protein; as this is arguably the most important component of the mass gainer. You want to avoid mass gainers that are primarily composed of cheap proteins like soy and whey concentrate. Other than that, as long as you stick to the types of proteins listed in our Ingredient Quality section above, you’ll be good to go in the protein department.
Other Active Ingredients
Some other ingredients that mass gainers will often have in them are digestive enzymes. These enzymes, such as protease (digests protein), amylase (digests carbs), and lipase (digests fats) are already present in our gastrointestinal tracts.
But when we’re eating a large amount of food with the goal of gaining muscle in mind, our digestive systems can take a huge hit. Because of this, the added digestive enzymes have the potential to aid in digestive processes, particularly in those with digestive issues [1].
Creatine is also another common addition to mass gainer supplements, and for good reason. Creatine has been proven time and time again to improve gains in strength and muscle mass [2,3].
Along with creatine, many companies will also provide particular amino acids, such as L-Glutamine, which increases the effects of skeletal muscle protein synthesis, potentially improving your gains and recovery [4].
Along with this, branched-chain amino acids (BCAA’s) may also be added to improve gains in strength and lean muscle mass [5]. If your mass gainer or protein powder doesn’t provide BCAAs and you’d like some, you can add a high-rated bcaa supplement to your routine.
As a way to “round out” the supplement and make it a true “meal replacement”, many companies will provide a comprehensive array of vitamins and minerals (which we all know of course are good for us [6]), just like you would see in many high-quality, whole-food meals.
Artificial ingredients and additives
If you are prone to digestive upset when consuming high amounts of calories or supplements in general, then you’ll want to avoid artificial ingredients and additives such as:
- sucralose
- acesulfame potassium (sometimes referred to as “Ace K”)
- gums such as xanthan gum, guar gum, and carrageenan
- high fructose corn syrup
- hydrogenated oils
Even if you don’t have any specific food sensitivities, eating a high-protein diet with the goal of gaining muscle takes a toll on your digestive system after a while. So you don’t want to make it worse by bombarding it with a myriad of synthetic ingredients that your body will have more trouble processing compared to more nutritionally wholesome sources.
Thickness & Mixability
A mass gainer will definitely be thicker than a standard protein shake just due to the sheer volume of the supplement. Although this is a given, the mass gainer should still be mixable with a standard shaker bottle and blender ball, as many people use this as a convenient, portable food option.
But if you prefer to use a blender instead, then that’s perfectly fine and you don’t really need to worry about mixability too much. But if it won’t even mix well in a blender, then you really have a low-quality product on your hands!
The best way to tell a product’s thickness and mixability is to check out user ratings and reviews, which are often found on the websites they can be purchased from. Some more helpful info on this can be found in our Brand Reputation and User Feedback sections at the start of this guide.
Taste and Flavor Options
There are many mass gainers out there. There are also a lot of different palates and tastes out there. The good thing is that there are many flavors to choose from, such as:
- Chocolate
- Strawberry
- Banana
- Chocolate Peanut Butter
- Peanut Butter
- Vanilla
- Cinnamon Toast Cereal
- Cookies n’ Creme
- S’mores
Need I say more?
Of course, each company will have different flavors (some more than others) and they’ll all taste different, even if they’re the same flavor but just happen to be from two different companies. While the best way to tell is to try it for yourself, you can also use our tips from our Brand Reputation and User Feedback sections of this guide to help you make the best decision for your taste buds!
Mass Gainer Ingredient Breakdown
Whey Protein
Now, this is perhaps the most common ingredient that you’ll find in a mass gainer. Although whey protein is a great way to pack on muscle mass, there are different types that you should be aware of [7].
The three main types are concentrate, isolate, and hydrolysate. The latter two are of the highest quality; going through a more tedious filtering process, thus having virtually no lactose or fats.
Concentrate is the less superior of the two, making it cheaper than isolate or hydrolysate. Having less lactose in your mass gainer supplement will help you to absorb more of it, as lactose often causes digestive issues in people when taken in high amounts [8].
Milk Protein Isolate/Casein Protein
These proteins are very similar, so we’re lumping them into one category here. These proteins are slower-digesting compared to whey protein, which is often what makes mass gainer supplements have such a thick consistency. It’s a great addition to whey protein in order to balance out the faster-digesting nature of the whey protein.
Vegan Proteins (Brown Rice, Pea, Hemp)
Vegan protein powders have been gaining popularity very quickly and for good reason. The best types of vegan protein powders provide you with a solid dose of protein using only plant sources which can help you avoid digestive problems (and moral ones) that come with dairy products.
These types of vegan proteins are the highest quality proteins you’ll find in mass gainer supplements. They’re the closest you’ll get to their animal protein counterparts if you’re a vegan, and you really can’t go wrong.
Maltodextrin
This is another common ingredient found in mass gainer supplements. This is a fast-digesting sugar and is often added to provide flavor, as well as a quick boost in energy and a non-filling source of easy calories. The inclusion of this ingredient only becomes an issue when it’s one of the very first ingredients on the list. This means that it’s very prominent in the supplement and that it’s used in an amount that’s much greater than necessary. Some is fine, but too much is just a way to waste your hard-earned money.
Low Glycemic Index (GI) Carbohydrates
Carbohydrates that rank low on the glycemic index (GI), which means that they don’t cause a rapid spike in blood sugar, are increasingly being used in mass gainer supplements. These include foods like oats, brown rice, sweet potato, bran, and buckwheat. This is because they provide a more stable release of energy from the calories that they provide, as opposed to high GI carbs like fast-digesting sugars, that’ll leave you essentially crashing and burning in just a short amount of time.
Nuts and Seeds
Nuts and seeds are a great source of heart-healthy fats [9]. Not only that, but along with the low GI carbs, provide a stable source of energy throughout the day. Fats are also very dense in calories (9 calories per gram as opposed to only 4 calories per gram for proteins and carbs), so it’ll help you to reach your calorie goals faster and easier. So look for flax, hemp, chia, peanuts, almonds, or cashews (just to name a few) the next time you’re in the market for a mass gainer supplement.
How to Get the Most out of Mass Gainer Usage
In order to get the most out of your mass gainer supplement, you must use it properly. This means that you shouldn’t take it when it’s not necessary.
What I mean by this is that it’s best to take it when you actually need it, like when you’re crunched for time and don’t have the means to make a substantial meal or you’re at work and you don’t have time to take that lunch break. But if you’re just sitting at home and you have the food necessary to make a high-quality meal for yourself but you just drink a mass gainer shake instead, that’s honestly just being lazy. And also, you’re just throwing your money down the drain, because although these supplements can help save you significant amounts of time, running through them faster than necessary will drain your wallet fast.
Now the proper way to go about consuming them is up to the individual, as everybody has different preferences as to how they like their shakes. Some people like to use a blender, some people like to use a shaker bottle. Some people prefer using milk, others prefer using water. It really doesn’t matter at the end of the day. Whatever’s most convenient and preferable for you, then that’s the option you go with.
As for timing, this also doesn’t matter too much either. But if we had to choose one “special” time to take this supplement, it would be post-workout, as the flood of protein, carbs, and amino acids would really help expedite the recovery process.
