MuscleTech 100% Mass Gainer Benefits

MuscleTech 100% Mass Gainer offers the following potential benefits. 

It can increase muscle growth

It’s no secret that protein is important for muscle growth. Made of amino acids, protein helps to grow, maintain, and repair muscles as well as shorten recovery time after exercise. However, protein alone will not increase your muscle growth. You must combine protein consumption with a workout regimen containing strengthening exercises in order to see results. 

It can help you gain weight

Every serving of MuscleTech 100% Mass Gainer contains 1,500 calories, which is three-fourths the recommended daily caloric intake for women and half the recommended amount for men. When combined with appropriate exercise, the ingredients in this calorie-dense protein drink can help you put on mass or maintain a healthy weight. 

It can provide a sustainable energy boost

The complex carbohydrates in MuscleTech 100% Mass Gainer can provide a steady stream of energy throughout the day. This can not only improve your overall well-being but also give you the energy you need to crush your workout routine.

MuscleTech 100% Mass Gainer Ingredients

MuscleTech 100% Mass Gainer contains the below ingredients. 

Protein blend 

MuscleTech 100% Mass Gainer contains 60 grams of whey protein in every serving. Whey protein contains amino acids like L-leucine that provide bursts of energy for the body and play a major role in muscle growth. 

Complex carb blend 

MuscleTech 100% Mass Gainer contains a complex carbohydrate blend containing a mix of oat bran, quinoa, and buckwheat. Complex carbohydrates are digested by the body more slowly than simple carbs and therefore provide a slower, more sustainable source of energy. 


MuscleTech 100% Mass Gainer contains creatine, a compound in the body and a popular ingredient in workout supplements. However, unlike many supplement ingredients, creatine has been clinically shown to help increase muscle gain and strength when taken in combination with proper exercise. It does so by producing immediate energy in the body for eruptive movements like sprinting or lifting.

Who Is MuscleTech 100% Mass Gainer Best For?

MuscleTech 100% Mass Gainer is best for people who want to increase their caloric intake and build body mass. With 1,500 calories in every serving, it is a no-nonsense protein powder designed to complement a bodybuilding lifestyle. However, it is useful for anyone trying to increase their strength and maintain a healthy weight. 

Claims vs. Reality

MuscleTech 100% Mass Gainer claims to help you get bigger, stronger, and achieve superior mass gains.

So can it? 

It contains 1,500 calories of high-quality, science-backed ingredients shown to support muscle health and increase muscle mass. However, taking this supplement alone will not deliver these results. Protein powders work best when in combination with a healthy diet and workout routine containing strengthening exercises.

Does MuscleTech 100% Mass Gainer Work?

MuscleTech 100% Mass Gainer contains ingredients proven to provide a steady stream of energy and support muscle growth. However, whether it will work for you depends on your current lifestyle, diet, and fitness goals. 

According to the National Institutes of Health, experts recommend that athletes consume .14 grams of protein per pound of body weight. This equals about 22 grams of protein for someone who weighs 160 pounds. 

If you are already getting your recommended protein intake, there is no proven benefit to taking a protein powder supplement. That being said, they can also be a great tool for ensuring you’re getting enough protein to support your fitness goals.   

How Does MuscleTech 100% Mass Gainer Compare?

MuscleTech 100% Mass Gainer is a potent protein powder with the potential to deliver serious gains. Let’s see how it compares to other protein powders on the market. 

MuscleTech Vs. Optimum Nutrition

MuscleTech 100% Mass Gainer is great for people looking for a no-fluff protein powder. However, Optimum Nutrition offers a similar product with additional beneficial ingredients including zinc, vitamin D, and vitamin C. Readers looking for protein powders with added health perks might prefer Optimum Nutrition Serious Mass. 

MuscleTech Vs. Naked Mass

MuscleTech 100% Mass Gainer is a high-quality product, but it contains dairy and soy. Readers with alternative diets might prefer a protein powder like Naked Mass. It is gluten-free, soy-free, nut-free, and free of artificial ingredients and flavors. 

Is MuscleTech 100% Mass Gainer Safe?

MuscleTech 100% Mass Gainer is a safe supplement with no known side effects. However, high-protein diets can lead to digestive issues like bloating, cramping, and gas. You should talk to a healthcare professional before adding a protein powder to your diet. 

Where to Buy MuscleTech 100% Mass Gainer

You can purchase MuscleTech 100% Mass Gainer online from MuscleTech’s website.
