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 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.

  • 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.


  • 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.

    Hey, Anthony. Inspect your label to be certain but it’s best to take 1 -2, depending on your dosage, before your activities.

    I started take this product since three month ago when I do a gym and still I’m using this product but I haven’t got any change till now why is this product is a fake one or why I don’t know


    Arnold (Editor)

    With three months of using it, Deo, it’s safe to say it may not be effective or simply non-reactive to your body. You might want to browse our site a bit for alternatives.
