Protein powder is one of the most popular supplements in the fitness industry, and there’s no shortage of options to choose from. Whatever your fitness goals and dietary preferences are, one of the best protein powders should meet your needs. 

However, this means that choosing the right protein powder for your goals can feel confusing, especially with so many different ingredients, additives, and marketing claims. Protein powder isn’t always cheap, so it’s important to make sure you’re making the right choice before ordering anything. 

In this GNC AMP Wheybolic review, I’ll be taking a closer look at GNC’s whey protein isolate, breaking down the ingredients, formulation, third-party testing, tasting notes, and everything else you need to know.

As with all protein reviews we write, we used our supplement testing methodology to assign a rating on a scale of 1 to 5, which scores the most important categories, including:

  • Formulation
  • Taste

  • Side Effects
  • Third-Party Testing

A Quick Look at GNC AMP Wheybolic

GNC is one of the most popular supplement retail stores, and in addition to carrying many of the top supplement brands, it also sells its own line of dietary supplements. AMP Wheybolic used both whey protein isolate and hydrolyzed whey protein, additional leucine, and Velositol®, a patented ingredient designed to increase muscle protein synthesis.

RELATED: Whey Protein Isolate vs Hydrolyzed 

The macros are similar to what you’d expect to see in a regular whey isolate supplement, though some flavors may be slightly higher in macros due to additives like creamer, cookie bits, and other additions depending on the flavor. 

The company also sells GMP AMP Wheybolic Ripped, which is the same protein marketed toward weight loss goals, with added caffeine and capsicum to provide a thermogenic effect and raise the body’s temperature. The caffeine is also a nice boost for those who use protein powder as a pre-workout beverage. 

Scoop size for GNC AMP Wheybolic.

GMP AMP Wheybolic is available in 17 flavors to match any taste preferences, including traditional flavors like Classic Vanilla, Chocolate Fudge, and Creamy Peanut Butter, as well as more unique flavors like Banana Milkshake and three licensed Girl Scout cookie flavors. 

Before You Buy

  • This protein powder is expensive but includes additional ingredients that may be beneficial for muscle protein synthesis.
  • The formulation includes a gum blend, multiple sweeteners, and different additives depending on the flavor, which is more ingredients than many other whey isolates.
  • Each serving contains two types of digestive enzymes, making this a great choice for those with sensitive stomachs.

Is GNC AMP Wheybolic Worth It?

At $2.80 per serving, this is one of the most expensive protein powders we’ve tested, but you’re paying extra for the added digestive enzymes, leucine, and Velositol®. If you want these beneficial ingredients, it might be worth it to you, but this formula isn’t for everyone. 

Great for:

  • Those with sensitive stomachs who struggle with dairy-based protein
  • Anyone looking to build muscle with a high-protein supplement
  • People who don’t mind artificial sweeteners and gum blends in exchange for great flavors

Not recommended for:

  • Anyone on a tight budget
  • People who want to avoid artificial sweeteners
  • Those who prefer a more minimalist whey protein isolate without many additives

Experience Using GNC AMP Wheybolic

For this review, GNC AMP Wheybolic was tested by GGR’s Head of Content, Nicole Davis, a certified nutrition coach and protein powder expert. She tested this with both milk and water, paying close attention to the solubility, flavor, mixability, side effects, and more. 

Overall, she enjoyed the flavor and texture, which was surprisingly good, and she was impressed by the high protein content. However, this protein is certainly expensive at $2.80 per serving, so while you’re getting plenty of protein with each serving, there are cheaper options if you’re looking to save some money. 

Price Per Serving

Each tub costs $69.99, and while the nutrition label includes macros for both one and two scoops, the instructions say to use two scoops, which means the tub has 25 servings.

At $2.80 per serving, this is one of the more expensive protein powders we’ve tested so far, and earns a 1-out-of-5 rating based on our protein testing standards.

RELATED: Understanding Protein Powder Labels

Formulation

The formulation earns a 5-out-of-5-star rating, with 40 grams of protein per serving, 1 to 2 grams of fat, and 4 to 7 grams of carbohydrates depending on the flavor. 

Wheybolic uses a blend of both whey isolate and hydrolyzed whey protein, which are two of the fastest-absorbing protein sources. It also contains added l-leucine (though whey is naturally rich in this amino acid), as well as Velositol®, a patented blend of amylopectin and chromium that may improve muscle protein synthesis1 when paired with whey protein. There are no other BCAAs, creatine, or other ingredients besides flavors and sweeteners.

RELATED: Whey Protein Benefits

Even though many people with dairy sensitivities find whey isolate easy to digest, like me, GNC has also added the digestive enzymes bromelain and lactase to select flavors, though not all flavors contain these enzymes for some reason.

Taste and Solubility 

Taste and solubility are two of the most important factors to consider, as nobody wants a chunky protein shake that you have to force yourself to drink. Nicole gave this a 4-out-of-5 score for the taste, noting that it has a unique chocolate flavor with a distinct fudge taste and very little artificial taste.

Solubility earns a 5-out-of-5 rating, as this protein dissolved very well in both milk and water.

Side Effects

Nicole didn’t experience any side effects, giving this category a score of 5 out of 5 stars, and I didn’t see any user reviews that mention side effects. Of course, as with any supplement, individual responses vary, so those sensitive to dairy may experience side effects.

Third-Party Testing 

For third-party testing, GNC AMP Wheybolic earns 4.5 out of 5. The label says “Banned Substance Tested,” but it’s not clear who does the testing.

To further test this protein, GGR hired an independent, accredited lab, Ellipse Analytics, to conduct our own unbiased third-party testing. We had over 150 protein powders tested for purity and label accuracy. For GNC AMP Wheybolic, we tested the Chocolate Fudge and Strawberries and Cream flavors, both of which were rated as “Meets Standard,” a passing score for our rigorous quality control. 

GGR collaborated with Ellipse Analytics, an accredited third-party lab, to test more than 150 protein powders. We screened for dozens of factors and rated each product against its peers. Excellent indicates the top 10% of products; Above Average is the top 25% of products; and Meets Standard is the top 50%.

We always recommend that you look for third-party testing when choosing a supplement, which ensures the product is safe from contaminants and contains what it claims on the label. Our testing also checks for heavy metals, but just because something is detected doesn’t mean the quantity is high enough to do harm.

GGR Score: 3.99 starstarstarstarstar

Product Highlights

  • Three flavors
  • 25g per scoop
  • 110 calories per serving
  • Under 1g of fat per scoop

Pros & Cons

Pros

  • 25g of protein
  • Only 110 calories per scoop
  • No added sugars
  • Under 1g of fat per serving

Cons

  • Reviewers state the taste is not the best
  • Doesn't mix well

Bottom Line

A protein powder that comes very close to being pure protein, at a reasonable price.

If you’re in the market for a good whey protein powder and want to save some money, Jacked Factory Authentic Iso is another great option.

Compared to Wheybolic, Authentic Iso is a very simple protein, with whey protein isolate as the main ingredient, and only a few other ingredients on the label. 

Each serving only contains 25 grams of protein, but even if you take two servings to get 50 grams, you’ll be spending less money for two servings of Jacked Factory Authentic Iso than you’d spend on a single serving of AMP Wheybolic. 

Overall, GNC AMP Wheybolic is the better choice for those who want the added leucine, Velositol®, or digestive enzymes, while Jacked Factory Authentic Iso is better for those who prefer a simpler, more affordable option.

Final Verdict of Our GNC AMP Wheybolic Review

Overall, GNC AMP Wheybolic has a great texture and flavor, passed our third-party testing, and uses high-quality whey protein isolate. However, with multiple added ingredients, the price is pretty high, which may deter some.

This is a very solid protein powder and a great choice if money is no issue, but those on a tight budget may want to look elsewhere.
