Mass gainers are excellent for those of you that are currently underweight, but they should not be taken lightly. If you are looking to build muscle but don’t mind a bit of body fat accretion then these are the products for you, just remember that you need to increase your exercise to match this.

Below we are going to examine ten of the best mass gainers that are out now, we will take a brief look at the company, the product, the ingredients, and the advertised benefits, and review them based on that.

Our Best 10 Mass Gainers – Weight Gainers for 2020

1. Optimum Nutrition Gold Standard Gainer

Optimum Nutrition Gold Standard Gainer

As always Optimum Nutrition are in the top ten, probably the most consistently reliable company out there, Optimum Nutrition have got an excellent Mass Gaining supplement for you with the Optimum Nutrition Gold Standard Gainer. Each serving (2 scoops) contains 770 calories, 55g of protein, 110g of carbohydrates, and 11g of fat.

The protein is mostly from isolates, but it is a mix so will be partly made from concentrate. The carbohydrate sources are oats, peas, and potatoes. Whilst the fat comes from chia seeds, flaxseed, and MCTs (usually found in coconut oil).

There are four flavors available: Cinnamon Bun, Colossal Chocolate, Cookies & Cream, and Vanilla Ice Cream. This product will seriously help you to maximize your recovery and results after a high-intensity weight training session.

2. MTS Nutrition Epic Gains

MTS Epic Gains

MTS Nutrition have tried to do something unique here with Epic Gains, creating a lean mass gainer. So whilst the other mass gainers out there are focused on high calories whatever the cost, MTS are trying to prevent fat gain. So a serving of MTS Epic gains is much lower calorie (296), whilst still containing a decent level of carbohydrates (36g of brown rice based carbohydrates).

The protein is a little on the low side at only 20g, but remember that two scoops would still be fewer calories than either Optimum Nutrition Gold Standard Gainer or Isopure Mass at only 592 calories with 40g of protein. MTS’ Epic Gains is a great choice for someone looking to build a bit of muscle, but trying to keep body fat low.


3. Nature’s Best IsoPure Mass

IsoPure Mass

Nature’s best Isopure range is well known for being of excellent quality. They have low carb, no carb, and regular carb protein shakes, and they also have the Isopure Mass that is definitely high carb! Each serving (6 scoops) contains 600 calories, 86g of carbohydrates, 53g of protein, and 5g of fat. Out of those 86g of carbs only 3g are sugar and 4g are fiber.

What’s nice about Isopure Mass is that it has roughly the same amount of protein as Optimum Nutrition Gold Standard Gainer but is 170 calories less. This shake is better suited to people who are looking to build muscle with minimum fat gain, while Optimum Nutrition have created a mass gainer for people who need to gain a lot of muscle and don’t mind as much about the fat.

4. Dymatize Super Mass Gainer

Dymatize Super Mass Gainer

While the last supplement we looked at was aimed at people trying to build muscle without any fat gain, Dymatize Super Mass Gainer could not be any different. This supplement is aimed at people who want to gain as much muscle as possible in as fast a time as possible, who will deal with fat build up later.

If you are the classic “Hard Gainer” then Dymatize Super Mass Gainer may be the answer to your prayers. Each serving contains 1300 calories! There are 52g of protein in each serving so the majority of these calories come from carbohydrates of which there are 254g per serving. This is huge. This is more carbohydrates in one serving of a supplement than most people get in their diet full stop. Whilst fiber is quite low at 5g, the fat content is also relatively low (10g per serving) meaning that you should still have a lot of flexibility in your diet afterward.

The protein comes from a combination of sources: egg protein, whey concentrate, whey isolate, whey hydrolysate, and casein protein. The shake is also absolutely packed with vitamins and minerals, something that a lot of mass gainers neglect.

5. Optimum Nutrition Serious Mass

Optimum Nutrition Serious Mass

We’ve already looked at an Optimum Nutrition Mass gainer with our first entry, and whilst “Serious Mass” comes from the same company, it couldn’t be any different. Whereas Gold Standard Gainer contained 770 calories per serving Mass Gainer contains 1259. Mass Gainer actually has 5g less of protein per serving, but it has 142g more carbohydrates! That’s more than double the serving (252g compared to 110g). There is also only half the fat content with 5.3g per serving rather than 11g.

Optimum Nutrition Serious Mass also has 25 vitamins and minerals, Creatine, and Glutamine contained in each serving. As always with Optimum Nutrition, there is a variety of fantastic flavors available.

8. Muscletech Mass Tech

Muscletech Mass Tech

With 840 calories per serving, 63g of protein, 132g of carbohydrates, 10g of creatine, and 7g of fat, Mass Tech is a very well balanced mass gainer. The carbohydrates come from multiple sources (millet, quinoa, buckwheat, and oat bran) as does the protein (egg, whey concentrate, whey isolate, whey hydrolysate). Five grams out of nine grams of fats are omega-rich, which is very decent.

This is a great mass builder for those of you who want to build a little bit of muscle but are worried about gaining too much fat. The protein per serving is absolutely massive, whilst carbohydrates are medium and fat is relatively low. The creatine is quite high but is still within your daily limits, but just pay attention to your body. You might benefit from dropping to 2-3 scoops rather than 5 to keep creatine to 5g per day.


9. Cellucor Cor-Performance Gainer

Cellucor Cor-Performance Gainer

Cellucor’s mass gaining supplement is a little different to the others on this list.

There are only 340 calories in each serving, and as a result, Cor-Performance Gainer would work well as a pre-workout (most others would be way too heavy for this).
