Mutant Mass Review - 5 Things You Need to Know


We’re hearing a lot of buzz about Mutant Mass. We wanted to see what the fuss was about so we dug deep into the ingredients, side effects, clinical research, and customer service. Afterward, we sorted through hundreds of user comments to see what people really had to say. Then, we condensed and refined to give you the bottom line.

What is Mutant Mass?

To begin with, Mutant Mass is a muscle-building product. It claims to make the ones you have larger, while making it easier to strengthen more, and gives you a good tasting way to make them grow. Ingredients include alanine, arginine, aspartic acid, cystine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine.

Mutant is the company behind Mutant Mass. According to the official website, they’ve been in business since 2006. You can buy directly from them, but several other retailers sell the product online. We like that it contains amino acids, but read on…

Mixed Reviews – “Some Here and Some There”

Our first concern is Mutant Mass is not a weight-loss product and, as such, the reviews are all over the place. “There are no appetite suppressants or fat burners in the formula. Amino acids are good for you and a necessary part of the diet, but don’t facilitate weight-loss on their own,” said our Research Editor.

”Made my stomach feel bad and had to go to restroom a lot,” claimed one frustrated user.

”The Banana strawberry doesn’t sit well with my stomach at all. Causing diarrhea and upset stomach every time I take it,” agreed another.

Others didn’t have this experience.

We found one happy customer who said, “This mass gainer tastes really good.”

And one dieter had this to say, “I have only used Mutant Mass for a week and already gained 5 lbs, half muscle. It really works, but you need to drink 2 servings a day. Always take it 2 scoops at a time, so space out your drinks evenly through the day.”

Price – “Expensive!”

A 15 lb. bag costs you $79.99 plus shipping and handling. Each one contains 26 servings of four scoops. Directions say you can enjoy two to three shakes a day, meaning that even at one shake a day you couldn’t get through an entire month with a single order.

”I can’t afford to use this stuff as much as they recommend,” said an upset customer.

”Even though you can get it cheaper at Amazon, it still adds up quick,” according to one review.

Some feel it’s worth every penny of the investment.

We found this glowing review from one customer, however. “I haven’t found a bigger bang for my buck than this. The cost to calorie ratio has everyone beat as far as I could tell.”

“This is the best bargain weight gainer I have found online. It balances affordability with above average ingredients at appropriate mixtures,” agreed another.

Over the years, we’ve learned that all takes is one issue like price, to stop any chance of long-term success. This, combined with the fact that it’s designed to help you gain weight, may be an issue for Mutant Mass.

The Science – “Amino Acids Build Muscle”

Amino acids are scientifically shown to build the protein our bodies need to make muscle. There are no studies with this product specifically, but you can get individual supplements in pill form for a much more cost effective choice. At DietSpotlight, we want to see science before we can recommend any product, but we want to know it also provides value to our readers.

The Bottom Line – Does Mutant Mass Work?

What’s the real deal with Mutant Mass? It’s not a weight-loss product, but rather a mass gainer for those who work out a lot and want to build more muscle. We’re hesitant to recommend this because our focus is on products that make it easier to lose weight.

If you’re ready to lose weight, we suggest using a supplement designed to help boost testosterone levels naturally. To get the most from it, use it with a balanced diet, increased water intake, and exercise routine.

Among the best products we’ve seen this year is Pronabolin. Rather than a hormone replacement therapy, it is a supplement that contains clinically tested ingredients shown to help boost testosterone levels naturally, making it easier for you to burn fat and build lean muscle.

Plus, the manufacturer is currently offering a Multi-Bottle Discount and 120-day money-back guarantee. This shows a great level of confidence in the product.

Previous Mutant Mass Review (Updated August 9, 2013):

What You Should Know

Mutant Mass is a product created by PVL. The product claims to be able to help make muscles bigger and give you more of them. It portrays itself as a "good tasting" way to help your muscles grow. It claims to be backed by two years of research to give you everything you need to get better results and faster. We will take a closer look at the product to determine if it is right for casual dieters.

List Of Ingredients

Mutant Mass contains: alanine, arginine, aspartic acid, cystine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine.

Product Features

Mutant Mass ingredients are nothing but amino acids. While amino acids are good for the body, they have nothing to do with weight loss. They do help support muscles, but they do not grow muscles. The more muscle a body has, the more fat it burns, and the better you feed the muscles, the better they will function. The key is, burning fat before it builds muscle. Using a product like this will not build muscle, and it will not help you lose fat. Without protein in this shake, there is no way to help the body feel full. Without feeling full, users are likely to feel hunger, and eat more. The main point of this product is to be a weight gainer, not weight loss. It is completely counteractive to most dieter's goals.


  • Mutant Mass contains amino acids which are helpful for the body.


  • Mutant Mass
  • Amino acids do not build muscle, they feed it.
  • This product is meant to be a weight gainer, not a product to help you lose weight.
  • There is no money back gaurantee for this product.
  • There are no free trials for this product.


Mutant Mass is a weight gainer! It's designed to help you gain weight to build more muscle, not to suppress the appetite or to help burn fat so you lose weight. This is not the product anyone who is looking to lose weight should use. If you want to lose weight, run away from this product and don't look back. Instead, turn to a product that contains either a fat burner or appetite suppressant, and if you can find one that contains both, great. The product should be clinically proven, and have enough of the clinically proven ingredients to be effective. To get more bang for your buck, exercise and eat a balanced diet.

    Precise to its product title, Mutant Mass is an clear-cut behemoth amongst weight gaining nutritional supplements.
    It packs a mess of exceptional ingredients needed, but perhaps the most extraordinary USP is the sheer amount of calorie count it contains – 1,060 kcal each serving!

  • Paul

    This product is a weight gainer. your not suppose to lose fat on it your suppose to take it while your on a training programme to keep the fat off and build muscle. second weight gainer reveiw i’ve read and its annoying me that its mentioned in both as a complaint that you dont lose weight with this product! thats the point! if your trying to lose weight why would take something that calls itself a weight gainer? and to answer Barry, if you think you will ever find any product or any amount of food, cause by the way to gain weight you need both, in five days, you’re seriously mistakin.. if you use extra water does a plant grow quicker? no. a good diet of lean meats and good veg through out the day with other good food sources like banana’s and peanuts for example along with this, or another weight gainer will help you gain weight, but not in five days. nothing noticable anyway. try something over two weeks

  • problem using your mutant mass
