The GNC Pro Performance 100% Whey has a formulation focused on delivering a high-quality protein blend, with an eye on both efficiency and taste. The primary ingredients, whey protein concentrate and whey protein isolate, are well-regarded in the fitness community. These forms of whey are known for their high biological value, meaning the body can easily and rapidly utilize the amino acids they provide. This is crucial for muscle recovery and growth, particularly post-exercise.

Whey protein concentrate, while slightly lower in protein content per gram compared to isolate, retains more of the naturally occurring nutrients found in whey. On the other hand, whey protein isolate is more processed to remove fats and lactose, making it a leaner option with a higher protein percentage. This combination offers a balanced approach, catering to those who value both nutritional richness and protein purity.

The inclusion of cocoa powder adds flavor, making the protein shake more enjoyable, which can be important for consistent supplementation. However, the presence of artificial sweeteners like sucralose and acesulfame potassium might be a downside for those who prefer natural ingredients or are sensitive to these additives. While these sweeteners are generally recognized as safe, some individuals might experience digestive discomfort or prefer to avoid them due to personal health choices.

Soy lecithin is included to enhance the mixability of the powder. It's a common emulsifier in protein powders, ensuring a smoother blend with liquids. However, those with soy allergies or sensitivities might need to be cautious.

Cellulose gum and xanthan gum are used as thickeners and stabilizers, contributing to the texture of the shake. While generally considered safe, their inclusion is more about the physical properties of the shake rather than nutritional value.

One area where the product could improve is by including additional beneficial ingredients like digestive enzymes, which can aid in protein digestion, or branched-chain amino acids (BCAAs) for enhanced muscle recovery.

A single serving of GNC Pro Performance 100% Whey offers 24 grams of protein, a substantial amount that is in line with the needs of most individuals engaged in regular exercise or bodybuilding. This amount of protein per serving is effective for muscle repair and growth, especially post-workout. The blend of whey protein concentrate and whey protein isolate is a strategic choice. Whey protein is a complete protein containing all nine essential amino acids, which are crucial for muscle recovery. The isolate form, being more refined, offers a higher protein content with less carbs and fat, making it an excellent choice for those looking for lean muscle gains or aiming to reduce calorie intake.


However, in the case of this product, we think it comprises substantially more concentrate than isolate, which would account for the higher carb content of the product.

Regarding the net carb and fat content, each serving contains 5 net grams of carbohydrates and 2 grams of fat. This is a moderate level of carbs that may not align with many expectations, however does help in replenishing muscle glycogen stores.

However, the effectiveness of a protein powder can also be influenced by additional ingredients that support muscle recovery, such as BCAAs, creatine, digestive enzymes, or added vitamins and minerals. The lack of these additional supplements in the GNC Pro Performance 100% Whey means that while it is effective in providing a high-quality protein source, it may not offer the enhanced recovery benefits seen in more comprehensive protein blends.



The chocolate flavor is quite enjoyable, offering a rich and pleasant taste that stands out among similar products. It has a rich and authentic chocolate taste that isn't overly sweet or artificial.

When mixed with milk, the texture is smooth and creamy, resembling a classic chocolate milkshake. It's quite enjoyable and easy to drink. However, with water, the texture becomes slightly less appealing. It's thinner and not as rich.

In terms of mixability, the powder performs better with milk. It blends smoothly, without leaving any noticeable lumps. With water, it required a bit more effort to achieve a smooth consistency. There can be some clumps if not shaken vigorously, which might be a slight inconvenience.



GNC Pro Performance 100% Whey is positioned as a mid-range protein powder, balancing cost and quality. The use of both whey protein concentrate and isolate offers a good protein source, though it's not the highest quality available on the market. The addition of artificial sweeteners and flavors may detract slightly for those preferring natural ingredients.

Relative Cost

When compared to other protein powders, this product offers a decent protein content per serving at a competitive price, making it a viable option for those on a moderate budget. However, it lacks some more premium features like added BCAAs, digestive enzymes, or natural ingredients. We did expect to see at least one of these included at it's price point.

Overall, GNC Pro Performance 100% Whey offers reasonable value for its price, especially for those who prioritize a balance between cost and protein content.



GNC Pro Performance 100% Whey Chocolate Supreme attempts to strike a balance between cost and quality, positioning it in the mid-range protein powder market. It offers a decent protein blend for muscle recovery and growth, though it lacks some more premium features like added enzymes, BCAAs, or natural ingredients. The taste is generally favorable, but mixability was a little more difficult in our case. This product is a good choice for those seeking a decent-tasting protein supplement without the frills of higher-end products. It's especially suitable for fitness enthusiasts who prioritize protein content over additional nutritional enhancements.
