Wheybolic Alpha Review

Getting to the gym consistently is a battle for many but it’s not the only one. If you’re looking to build up muscle mass, you must take into consideration your diet as well. Having a high-quality protein source to refuel your muscles and recover for optimal strength building is essential which is why many consumers have started grabbing for GNC’s AMP Wheybolic Alpha protein powder with Myotor. 

AMP Wheybolic Alpha is a protein powder geared towards building muscle strength and size while also supporting testosterone levels. But does this supplement stand out from the rest or is it just another whey protein? Let’s find out.

About Wheybolic Alpha

According to their website, Wheybolic alpha is clinically proven to support muscle growth, strength, and stamina, while also supporting testosterone levels with Testofen. It is recommended for both pre- and post-workout as well as cardio use and on non-training days in between meals. It is gluten-free and naturally and artificially flavored in chocolate fudge.

Wheybolic Alpha Benefits

AMP Wheybolic Alpha is advertised as clinically effective for muscle building, increased strength, and exercise stamina. GNC attributes its benefits to the rich source of essential amino acids (EAAs) with an emphasis on leucine, a branched-chain amino acid (BCAA) that is associated with increased muscle protein synthesis (MPS), the act of creating new muscle tissue. 

This product also boasts testosterone level support with the use of Testofen, also known as Fenugreek, which is believed to help further assist in increasing muscle strength and mass. Along with this AMP Wheybolic alpha contains 650mg of Myotor which is a blend of two herbal ingredients Sphaeranthus Indicus (also known as East Indian globe thistle) extract and Magnifera indica (better known as mango tree) bark extract for even further muscle support.

Wheybolic Alpha Ingredients

The main active ingredients in Wheybolic Alpha are the EAA, leucine, Myotor, and Testofen.

EAA are the building blocks for protein and are required in our diet to build and maintain muscle mass. While EAA are important for general health, they are also a requirement when trying to increase lean body mass. One of the easiest ways to get adequate EAAs in your diet post-exercise is by consuming a whey protein powder, which is quick digesting, contains all essential amino acids, and is particularly rich in BCAAs which are associated with increased MPS. AMP Wheybolic Alpha contains 40 grams of whey protein powder per serving. 


Leucine is one of the three BCAAs that is found in higher doses in GNC’s AMP Wheybolic Alpha supplement. Research has found leucine is associated with an increase in MPS and can help inhibit protein breakdown following intense exercise. Many studies support the use of higher concentrations of leucine in supplements, particularly those that also contain a rich source of EAA for the best results in muscle building.


AMP Wheybolic Alpha contains 650mg of Myotor which is a blend of Sphaeranthus Indicus (also known as East Indian globe thistle) extract and Magnifera Indica (better known as mango tree) bark extract. This herbal combination is believed to support muscle endurance to increase number of reps and overall strength however, further research is still needed with larger sample sizes.


AMP Wheybolic Alpha also contains Testofen, which is made from concentrated Fenugreek extract. Testofen is believed to help support rapid improvements in exercise performance and capabilities however, further research utilizing larger sample sizes is still needed.

Does Wheybolic Alpha Work?

Based on the ingredients in GNC’s AMP Wheybolic Alpha supplement and the subsequent research available it is likely that this product will help aid in muscle growth and improved exercise recovery when taken as directed. While some ingredients, such as Testofen and Myotor are lacking in adequate clinical trials, the research that is available is promising and not likely to result in any adverse health effects.
