1. NutraBio Extreme Mass 6 lbs

Our rating: 9 / 10

NutraBio Extreme Mass 6 lbs

Check Price on Amazon

Pros:

  • Very effective at helping achieve results
  • Build lean muscle easily and effectively
  • Provides sufficient calories for a mass gainer
  • Losing weight improves energy levels, which helps with building muscle

Cons:

  • Lacks many of the amino acids that are needed to build muscle
  • May not be suitable for most diets

This is a mass gainer that contains many essential bodybuilding nutrients for men, including a great deal of calories. It also contains so many carbohydrates that it has a very undesirable taste that’s not perfect for most tastes, but many who want to gain weight have said that it’s easily worth the bad taste if it means they’ll increase their mass.

Some users have also noticed that they have to take two servings per day in order to get the calories that they need. There are only a few calories in each serving, so that’s why it’s important to divide it twice. It’s usually taken first thing in the morning with the goal of building muscle during the day.

If you prefer to take one serving at time, and you still want a big number of calories, this is probably not the right mass gainer for you.

Frequently Asked Questions (FAQ)

What is the best mass gainer for skinny guys?

There are two types of mass gainers you need to know about: high protein mass gainers and regular (or light) mass gainers. A high protein mass gainer will help you build lean muscle mass quickly and fatigue less easily.

I suggest you start off with a high protein mass gainer until you put on some muscle weight and then switch to a regular mass gainer. A regular mass gainer is appropriate for those of you that have already gained some weight and want to bulk up.

A high protein mass gainer is ideal for those who are young (between 16 and 30 years old), skinny, or just beginning their fitness journey. We have included the best high protein mass gainers in our post.

What is the best tasting mass gainer?

Optimum Nutrition Serious Mass Gainer is the most purchased mass gainer and this is because of it’s flavor and effectiveness in supporting muscle growth. The suggested use is to mix one scoop of powder with 18+o fluid ounces of liquid and drink in between breakfast and lunch. Serious Mass Gainer contains enough calories and protein to support muscle growth without causing fat gain, a feat most competitors will not attain.

How can a skinny guy build muscle fast?

When you are skinny, your energy and muscle building efforts will likely be better spent adding lean muscle mass directly. The easiest way to do this is to gain weight, as you will also gain some muscle mass along with it.

The best way to do this is to consume a high calorie diet, eating at least 3 meals per day with healthy snacks in between meals. Take in a lot of whole foods with fiber and protein, using natural fat in moderation, and try to eliminate processed foods from your diet. Follow a reasonable exercise program, doing compound exercises that use a lot of muscle at a time. Try to supplement with a quality multivitamin and protein powder.

In general, you might try to follow a combination of the same strategies that are recommended for skinny guys, focusing on nutrition. You also might try to focus on some very basic muscle building exercises like bench presses, chin-ups, deadlifts, squats, push-ups and dips.

Which is best mass gainer or super gainer?

Within todays market there are literally hundreds of different Protein Powder and Mass Gainers which are specifically designed to help people gain reduced weight and build muscle, some are better for some people than others, here you can find the top 15 best mass gainers for skinny guys:
