The 7 Best Mass Gainers Reviewed

Are you struggling to put on weight? Have you been working out with no marked increase in muscle mass? Do you envy large, hulking muscles on other people at the gym, only to be disappointed with your lean gains? You’re not alone. While many people focus on cutting weight as part of their workout journey, an equal portion of people struggles to bulk up. Not only does this slow your performance and contribute to lesser muscle mass, meaning fewer gains and less strength, it can also significantly drop your morale, making you feel like working out isn’t worth your time. While you may have reached for protein shakes and tried packing on the carbs, for some people the weight just won’t stick. That’s where mass gainers come into play.

If you find yourself struggling to gain muscle mass, or are fighting against a fast metabolism and low protein levels, mass gainers can give you the competitive edge you need to push yourself to the limits and see real results. Some mass gainers can help you gain up to 10 pounds in just a month with consistent use, allowing you to build those strong, defined muscles you’ve always dreamed of. But what are mass gainers, and how do they work?

If you are in a hurry, our pick for the best mass gainer is Transparent Labs ProteinSeries Mass Gainer.

What are Mass Gainers?

Anyone who has tried to bulk up knows you need to consume more calories than you burn to see real weight results. But for some people, consistently getting the right number of calories through your traditional diet can be hard to balance and ensuring that these extra calories don’t come from harmful sources like sugars or junk food can leave you feeling exhausted. Mass gainers offer you carbs and proteins, as well as additional calories and amino acids, in a convenient beverage form, allowing you to simply drink those extra calories and beneficial nutrients right down before and after your workouts.

Unfortunately, not all mass gainers are created equal, which is why we’ve gone ahead and found the best mass gainers on the market, so you can partake with confidence knowing you’re getting the best of the best. Without further ado, here are our top picks for the best mass gainers out there.

Frequently Asked Questions About Mass Gainers

Still have questions about mass gainers? Don’t worry, we’ve gone ahead and answered some of the most common questions for you, so you can make an informed decision about what’s right for your body.

How Do Mass Gainers Work?

The simplest way to put it is that mass gainers give your body added calories to burn, but the real answer is more complicated than that. By offering you a combination of carbohydrates, which your body can burn for energy, as well as protein, which your body can use to build larger muscles, as well as sustain your energy levels longer, you can boost your body’s natural processes to new heights. When combined with exercise and a healthy diet, mass gainers allow you to intake more calories than you could usually get from meals alone, allowing your body to have the fuel it needs to take on harder and longer workouts, without losing muscle mass. For those with faster metabolisms, the added calories allow your body to start storing body fat, as well as have the building blocks it needs to create larger, stronger muscles.

What is the Difference Between a Mass Gainer and a Protein Shake?

In general, the real difference between mass gainers and protein shakes is the number of calories present in each. Many protein shakes focus on giving you a boost in protein levels, while still keeping your calorie count low. While this is ideal for anyone looking to lose weight or counting their calories, it is not ideal for anyone looking to bulk up quickly. Mass gainers, on the other hand, offer you protein in conjunction with a high carb count and an even higher calorie count, allowing you to fuel your body for your next workout while still getting the nutrients you need.

Who Can Benefit from Mass Gainers?

Mass gainers are ideal for anyone with fast metabolisms, or who are looking to add on higher levels of muscle mass quickly and efficiently. Mass gainers can help you maintain a healthy weight while still increasing your overall muscle mass and burning excess fat. As with any supplement or dietary change, it is best to talk to your doctor before making any changes, as some people will not react well to swapping out a meal with a mass gainer or may experience digestive issues as a result of the change.

How Soon Will I See Results?

As with any supplement, it can take up to two months to see results. Consistent usage is the best way to ensure you get the most out of your mass gainer, and any protein supplement should be paired with exercise routines and a healthy diet to see the best results. If you have not seen any changes in two months you may need to switch to a different muscle gainer or may be better served to revisit your exercise routine or diet to see what works best for you. As with any health decision, it is best to consult your doctor or nutritionist before making a large change to your lifestyle.

Mass Builder Buying Guide

When shopping for a mass builder, the number one thing to keep in mind is the ingredients present in each option. While most mass builders will rely on whey protein or other dairy ingredients as a consistent source of both proteins and carbs, this may not be ideal if you have a dairy sensitivity, so it may be best to find another product that will work for you.

Your body can perform best when you give it good, natural fuel, and the same applies to any supplement you take. Ensuring that the ingredients in your mass builder are natural and sustainably sourced will ensure you get the best of the best for your body every time.

Keep in mind your caloric goals before starting a mass gainer, as it is easy to misjudge the number of calories your body needs in a day. Don’t swap out a mass gainer for every meal of the day, and be careful about running a calorie deficit while taking a mass gainer, as it may lead to vitamin deficiencies depending on the product you are taking and how balanced your overall diet is.

Finally, if you are stuck between two different mass gainer options, reach out to your trainer or a nutritional specialist to find out what will work best for you. As everyone has different body types, different formulas can have unique impacts on your body. It is always a good idea to consult with your healthcare professionals before changing your diet, and it can be helpful to keep a daily log of any symptoms or changes you feel while on the supplement to better track your results.

Remember: as with any supplement, you need a combination of a healthy diet and exercise to see the best results.
