7 Best Weight Gainers Review In 2022 [Review and Buying Guide]

Best Weight Gainer

Increasing muscle mass and strength can be difficult if you’ve never tried gaining weight before, especially if you have a fast metabolism and a high-calorie nutrition goal.

Weight gainers are a supplement that provides you with protein, fats, and carbohydrates that your body needs without needing to stuff your body with food every hour. They are great for individuals with lackluster appetites or schedules that don’t allow them to cook healthy meals.

However, understand that not all mass gainers are healthy. Some products are loaded with filler carbohydrates, and low-quality whey protein concentrates. If you choose the wrong mass gainer protein, you’re going to end up getting fat and have constant unwanted stomach upsets.

We’ve reviewed the top 7 best weight gainers found on Amazon and have concluded that Chocolate Less Naked Mass is the most delicious and healthy weight gainer we’ve ever had. With only five ingredients and no additives, GMOs, growth hormones, artificial flavors, or sweeteners, it’s a great alternative if you need a clean meal on the go.

Although a bit more expensive than the rest, Chocolate Less Naked Mass is healthier and will be more beneficial to your body in the long run.

Weight Gainer Buying Guide

What Is Your Reason For Purchasing Mass Gainers

Different body type
Different body type

Before you purchase any Mass Gainers, make sure you understand your body type.

Are you a person looking to gain weight, keep the weight, or find a meal replacement for your busy life?

If you’re a person looking to gain weight, looking for a mass gainer with more carbohydrates can be beneficial.

If you’re looking to keep the weight, looking for a mass gainer balanced with carbs, proteins, and carbs can be beneficial.

If you’re looking to find a meal replacement for a busy life, looking for a healthy mass gainer alternative can be beneficial.

Common Ingredients Found in Mass Gainers


To build muscle, you need to have protein. When you lift weights and exercise, you create tiny micro-tears in your muscles. Protein helps aid the recovery and repair the tears to make your muscles bigger and stronger.

Mass Gainers are packed with different types of protein. Whey, Casein, Soy, Rice, or Eggs are some blends that you may find. If you are lactose intolerant, casein and whey protein may not be good for your digestive system so choose a plant-based protein such as soy or rice.


Carbohydrates provide you with the energy and fuel to run your body during intense weight training and cardio workouts. This allows you to work harder and accelerate your muscle-building process. Weight Gainers are packed with carbohydrates so you’ll be able to recover quicker and have more energy to crush your workouts.


Creatine provides additional phosphocreatine in your muscle helping your body create more ATP. This provides you with the energy and strength in your muscle to get that extra rep when you’re lifting and that little energy boost when you’re running.

What to Look for When Buying Mass Gainers

Carb and Protein Ratio

The better mass gainers contain a 3:1 or 4:1 ratio of carbs and protein. This is because it provides enough nutrients to help replace the glycogen levels (energy levels) and refuel your body so it can begin repairing your muscles. Without it, you’re using your own body’s nutrients to help repair your body.


It takes weeks to gain the necessary healthy weight. If you increase your weight too fast, you may face some health problems. That is why for long term results, research and find a mass gainer that works on your budget.


Authentic and Well-Known Brands are always the way to go. Fake and cheaper brands often contain harmful ingredients and are processed with bad chemicals. Do not compromise your health for a cheaper alternative.

Mixability and Taste

Mass Gainers come in a variety of flavors. As you will be drinking a lot, make sure you can switch up the flavors from time to time. Also understand that some mass gainers don’t mix well with standard blender bottles or a spoon. You may need an electric blender so it doesn’t get chunky. Find one that is easy to mix and drink.


Understand the micronutrients and macronutrients that you’re ingesting into your body. Not all weight gainers are healthy and often use cheap ingredients to get you the calories you need. Usually, this results in more bloating, sickness, and cramps.

Serving Size

Some mass gainer supplements have six scoops of powder per servings and often more. This makes it very difficult to blend and drink. Make sure you look at how many scoops you need to get the right amount of calories, minerals, and vitamins.

How Do Weight Gainers Work?

Weight gainers are a supplement powder that contains a ton of calories and nutrients in each serving. Like a protein shake, you’ll mix up the powder in milk or water but usually, they are thicker than protein shakes.

To gain weight you need to consume more calories than you consume. The leftover calories that are not consumed are stored in your body as fat and protein that is used to build your muscle. This is called caloric surplus.

However, if you consume too much you may store too much fat which may cause health problems. That’s why it’s crucial to find the right weight gaining powder to consume.

Mass Gainers are a replacement for a regular meal, as it takes a few seconds to digest all the calories. This saves hours cooking, meal prepping, cleaning, and eating.

What Is the Difference Between Weight Gainer Powder and Pill?

Weight Gainer Shakes provide an immediate increase to your calorie intake while Weight Gainer Pills provides a natural boost to your appetite. This increases your food cravings, making you eat more and take more calories throughout the day.

Weight Gainer Pills also has the ability to slow down your metabolic rate or the rate your body burns calories. This allows you to gain weight more easily.

How Do You Take Weight Gainers Properly?

To gain weight, you need to consume more calories than your body burns. Here is an indicator to help you measure how many servings of weight gainers you need:

To gain around 3 lbs of muscle per month: Two servings of weight gainer each day (One serving during breakfast and One serving after workout or at least four hours after the first intake)

To gain around 5 lbs of muscle per month: Three servings of weight gainer each day (One serving during breakfast, One after workout, and One before going to bed)

To gain around 7 lbs of muscle per month: Four servings of weight gainer each day (Two servings during breakfast, One after workout, and last before going to bed)

To gain around 10 lbs of muscle per month: Five servings of weight gainer each day (Two servings during breakfast, One after workout, and Two servings again before going to bed)

FAQs for Weight Gainer Shakes

How Long Till I See Results Taking Mass Gainers?

You can see results within a few weeks. Understand that you have to be eating a calorie surplus to increase your weight. Make sure you’re eating nutrient-dense foods and healthy meals and taking mass gainers to see an increase in weight.

What Is The Difference Between A Mass Gainer Supplement and A Protein Powder?

Traditional protein powder is mostly protein (10 g to 30 g) with little carbs and calories. Traditional mass gainers have more protein (30 g to 60 g), carbs, and fats.

Will Mass Gainers Make You Fat?

If your diet consists of only carbs and calories without exercising, you’re more than likely to gain fat weight. Make sure you’re getting enough exercise to burn off the excess fat from your body.

Are Mass Gainer Supplements Safe?

Mass gainers are safe if you take the recommended dosage. If you’re unsure and worried, we recommend you to talk to your doctor before taking any supplements. If you’re taking medication or in a treatment plan, it might have side effects when taking weight gainers.

Can You Mix Other Supplements With Mass Gainers?

Yes, you can mix protein, creatine, or any other supplements you need to your shake. You can also add peanut butter, berries, and other superfoods to increase your calorie intake.


Most weight gainers are loaded with bad carbs, ingredients, and chemicals, making your body feel bloated, inflamed, and sick. Out of the six mass gainers that we research, we recommend Chocolate Less Naked Mass.

With only five ingredients and no growth hormones, artificial flavors, sweeteners, gluten, or say, it is healthier and filling weight gainers on the market. With BCAAs and other essential nutrients, your body is going to feel great with the faster recovery.

The other mass gainer that was very close was Muscle Milk Gainer. Its Milkshake-Like taste makes it easy to consume and get the calories you need to gain weight. Combining fast and slow-release proteins in the weight gainer, Muscle Milk ensures your body always has protein assisting muscle growth.

We chose Chocolate Less Naked Mass and Muscle Milk Gainers because they are healthier alternatives than the other weight gainers.

Muscle Milk is Lactose and Gluten-Free. While Chocolate Less Naked Mass has only five healthy ingredients in its powder. Although they are a bit more expensive, it is worth the investment in eating higher quality foods.
