What is ReBuilt Mass?

First off, ReBuilt Mass is a super-anabolic powdered supplement. The ingredients include creatine hcl, creatine citrate, micronized creatine monohydrate, creatine akg, creatine ethyl ester hcl, micronized l-arginine, micronized l-methionine, micronized l-glycine, micronized guanidinoacetate, micronized akg, leucine, whey protein concentrate, whey protein isolate, calcium caseinate, soy protein isolate, hydrolyzed whey peptides, l-leucine, betaine anhydrous, quercetin, Testofen fenugreek seed extract, hmb, Sustamine (l-alanyl-l-glutamine), BioCore Edge (protease and peptidase). It’s supposed to help increase muscle growth and size, improve strength and power for workouts. You’ll need to add three scoops to 16 ounces of cold water or milk. It can be used once daily.

We are not sure when ReBuilt Mass was first released, but we do know this supplement is made by GNC and is a part of the Beyond Raw product range. It’s available in a variety of flavors and sold exclusively at the retailer. We like that is contains a few natural ingredients and that we found some favorable customer comments, but read on…

Unsavory Taste – “Can You Handle It?”

The first concern was the unsavory taste of ReBuilt Mass ingredients. “When the product is available in flavors like vanilla cake batter, cookie brownie and strawberry milkshake; users expect the best,” said our Research Editor. “Unfortunately, what users experienced wasn’t a good.”

One user stated, “This is what really disappointed me. I couldn’t even drink it without gagging, which is why I just stopped using it.”

“This tastes nothing like cake batter,” reported another.

On the other hand, not every review of ReBuilt Mass mentioned the taste.

“I bought it, and the first days it was helpful. I was gaining weight. Taste is pretty good,” stated a user.

Another revealed, “Taste is okay. Works well as a mass gainer.”

High Price – “Another Issue?”

Based on ReBuilt Mass reviews, another concern was the high price. One customer said, “This supplement is quite pricey to say the least. We’re talking $88 a tub. This is only 11 servings. You do the math.”

“I buy a lot of supplements. This is one of the more expensive ones,” commented another.

We found some ReBuilt Mass reviews that didn’t mind the cost of the supplement.

“A bit pricey, but lower than the competition,” stated a consumer.

“I stated to see results so the price was worth it,” posted another.

Our research has revealed that if there is a particular aspect of a fitness supplemen that is especially problematic, like being pricey, the likelihood of long-term success is slim. Is it really worth it if customers can’t afford ReBuilt Mass?

The Science – “Is ReBuilt Mass Researched?”

Unfortunately, we did not find any clinical research presented on the official GNC website for ReBuilt Mass. However, this product does contain ingredients such as creatine monohydrate to help fuel and build the muscles. While it may produce some results, there’s nothing connected to this formula. At DietSpotlight, we prefer to see some actual studies that support the product we’re reviewing.

What Users Are Saying

"”My boyfriend liked the taste and has been taking it for several months now. He drinks it before our workouts at 5 AM and it provides him with the energy boost he needs for our morning workouts.”"

"”It tastes so horrible, I could barely drink it. I was not satisfied with this product. I am looking forward to a different protein shake.”"

The Bottom Line – Does ReBuilt Mass Work?

So, should you run out to GNC and buy a tub of ReBuilt Mass? Well, we like that this fitness supplement contains a few natural ingredients and that we found some positive customer comments. However, we have some doubts about this formula since there is no clinical research supporting the claims. Moreover, we’re a little concerned about the fat price tag and unsavory taste.

If you really want to increase physical performance and build lean muscle mass, we suggest going with a product containing ingredients supported by documented research, does not have an unpleasant taste and will not cost you an arm and a leg.

Among the best products we’ve seen this year is our product called Pronabolin. The formula offers nine ingredients. All clinically-tested with results often found in publications such as The Aging Male.

Also, we’re so confident that you’ll love our supplement that we’re offering customers a 120-day money-back guarantee and multiple-bottle discounts, which is a good sign.

What You Should Know about ReBuilt Mass

GNC is a major name in the supplement market and the new Beyond Raw line is ideal for bodybuilders. The products are designed to be stacked together as needed. There are fat burners, lean muscle stimulators and mass gainers. Re-Built Mass is all about promoting muscle growth. We find several common ingredients, but the way GNC puts these ingredients together is astounding. Creatine and protein are the main ingredients. When we look at creatine we look for monohydrate, ethyl ester and micronized and we found all three in this supplement.

List of ReBuilt Mass Ingredients

Advanced Creatine Complex: Creatine HCl, Creatine Citrate Micronized Creatine Monohydrate, Creatine AKG, Creatine Ethyl Ester, Micronized L-Arginine, Micronized L-Methionine, Micronized L-Glycine, Micronized Guanidinoacetate and Micronized AKG.

Leucine: Whey Protein Concentrate, Whey Protein Isolate, Calcium Caseinate, Soy Protein Isolate, Hydrolyzed Whey Peptides and L-Leucine.

Carbohydrate Blend: Maltodextrin and Waxy Maize Starch.

Protein Blend: Whey Protein Concentrate, Whey Protein Isolate, Calcium Caseinate, Soy Protein Isolate, Hydrolyzed Whey Peptides and Cocoa.

Fat Blend: CLA Powder and Medium Chain Triglycerides.

Quercetin, Fenugreek Extract, HMB Powder, Sustamine, BioCore Edge, Brown Seaweed.

Product Features

We don’t usually look at an ingredient list once and give a product the thumbs up, but we did with Re-Built Mass. This supplement is not for dieters, so we put on our bodybuilding hats and found everything we wanted in this mass gainer.

Creatine is important to bodybuilding, but there are several kinds of creatine and some are micronized for easy absorption while others are not. GNC does not take any chances. The company includes creatine monohydrate, creatine ethyl ester and micronized creatine.

Protein is the other important ingredient is a mass supplement like Re-Built Mass. Whey protein is fast-acting, while casein works slowly feeding the muscle for a longer time. Re-Built Mass includes both whey and casein protein.

Advantages of ReBuilt Mass

  • Looks like the perfect creatine/protein supplement for bodybuilding.
  • Ingredients are listed online.
  • Available for sale from the official GNC website.
  • Can be stacked with other Beyond Raw supplements.

Disadvantages of ReBuilt Mass

  • Will cause water retention.
  • May not be available in all areas.


If a bodybuilder is looking for the perfect creatine supplement, they may not have to look any further. There are nearly 70 reviews for the product on the GNC website and all have positive things to say about the mix. There are some problems, however. It does not mix well and it is expensive, but isn’t it worth it if you gain muscle faster?

Dieters should not take the products in the Beyond Raw line. These are designed for bodybuilders only. Creatine will cause weight gain via water retention.
