Experience Using Jacked Factory Authentic Whey

According to Jacked Factory, Authentic Whey works well mixed with water, milk, or almond milk. Consider blending the one-scoop serving in a shake or mixing it with oatmeal or Greek yogurt for variety. You can take it post-workout or between meals to enhance your overall protein intake. Authentic Whey should be used to supplement a well-balanced diet of whole foods.

Our product tester, GGR Performance Editor Anthony O’Reilly, CPT, tried the Fruity Cereal flavor of Authentic Whey. He thought the flavor was alright, but it didn’t quite live up to his expectations and he would have liked to try the other flavors. 

Price Per Serving

On the Jacked Factory website, a tub of Authentic Whey costs $34.99 for a one-time purchase at the time of writing. There are 30 servings per container, meaning each serving costs $1.17. We rated the price per serving a 4 out of 5 considering serving size prices generally range between $1 to $2 for most protein supplements. 

If you want to save even more, Jacked Factory offers a subscribe and save 15% option. You can choose to receive a new order of protein every 30, 45, or 60 days and shipping is free within the USA. When you subscribe, each tub costs $29.74 and the price per serving is just $1. 


This Jacked Factory whey protein boasts a high protein content and low levels of carbs and fat, earning it an excellent formulation rating of 5 out of 5.

Each serving contains 24 grams of protein from whey concentrate and whey isolate. Whey concentrate and whey protein isolate are both considered high-quality proteins1, though whey concentrate contains more lactose and fat, and whey protein isolate undergoes additional filtration to reduce these components. Despite their differences, they contribute minimally to the overall carb and fat content of the product.

RELATED: What is Whey Protein?

Twenty-four grams of protein is enough to stimulate muscle protein synthesis, a process required for the repair and rebuilding of muscle mass. Research indicates2 that consuming between 20 to 40 grams of protein every three to four hours is ideal for muscle growth.

With only 2 grams of fat and 1 gram of carbohydrates, Authentic Whey makes it easy to increase your protein intake without significantly affecting your other macros. This is ideal for individuals aiming to minimize changes in body fat while building muscle and boosting metabolism.

Authentic Whey is free from added sugar and is sweetened using sucralose and stevia extract. Sucralose, an artificial sweetener, is generally well-tolerated, but some individuals experience abdominal pain and gas. Stevia extract is a zero-calorie natural sweetener that’s approximately 250 to 400 times sweeter than table sugar. Furthermore, Authentic Whey contains no fillers or dyes. 

Taste and Solubility 

Our GGR expert product tester Anthony O’Reilly, certified personal trainer and nutrition coach, tried the Fruit Cereal Splash flavor of Authentic Whey and rated the taste a satisfactory 4 out of 5. Anthony says, “It tasted like Froot Loops but with a slight medicinal aftertaste.” While it wasn’t anything that turned him off from the product, it’s worth mentioning. 

The protein powder is white until mixed with liquid where it then turns red. Anthony rates the product’s solubility a solid 5 out of 5 and says, “It mixes easily but there’s some separation that was spotted when I accidentally spilled this on my counter.” Had he not spilled it, the separation likely wouldn’t have been noticeable. 

Side Effects

Anthony didn’t experience any whey protein side effects after taking Authentic Whey. As previously mentioned, some individuals who consume sucralose complain of abdominal pain and bloating, however, there’s a lack of research3 linking these symptoms directly to artificial sweeteners.

Additionally, lactose is the main carbohydrate in whey protein and may cause gastrointestinal discomfort in consumers who are lactose intolerant. Side effects like gas, bloating, diarrhea, and abdominal pain can occur in these individuals when lactose is ingested.

Furthermore, anyone with a milk allergy should avoid consuming whey protein, since whey is extracted from cow’s milk. An allergic reaction could result in hives, facial swelling, rashes, or throat swelling. In serious cases, anaphylaxis could occur.

Before incorporating a new dietary supplement into your routine, be sure to consult with your healthcare provider. They can ensure its safety in conjunction with your medications and any existing health conditions.

Third-Party Testing 

Jacked Factory Authentic Whey is not third-party tested. We highly encourage seeking third-party tested supplements to ensure quality and safety, especially if you are an athlete who gets tested for banned substances. As the Federal Drug Administration (FDA) does not regulate supplements, opting for third-party tested products is ideal to verify label accuracy and to confirm they do not contain harmful levels of heavy metals or other contaminants.
