The MuscleTech Phase8 is a protein powder with sustained-release formula that ensures a long-lasting effect. You can choose among the many different sizes and flavors, like chocolate, strawberry, vanilla, milk chocolate, and white chocolate. The Phase8 was launched in 2012, and was priced at $28.24 for two pounds and $43.24 for 4.5 pounds.

Key Features

The Phase8 contains half the carb and fat content of the leading competitor’s blends. It also does not use any fillers. With its high-quality protein sources derived from milk, your body is guaranteed optimal recovery and muscle repair. The product description listed the protein blend as Hydrolyzed Whey Protein Isolate, Whey Protein Concentrate, Whey Protein Isolate, Milk Protein Concentrate, Micellar Casein, and Calcium Caseinate.

Its manufacturer boasts about its wide variety of flavors and amazing taste. Other notable features include the slow-release formula for a long-lasting effect, and the six high-quality milk- derived protein sources. The company also highlighted how easy it is to mix the Phase8 with milk or water. Each serving comes with 2.2 grams of glutamine, 4.6 grams of BCAAs, 6 protein sources, and 26 grams of protein.


The Phase8’s protein formula was designed for the muscle, and not really for weight gain. It works by release amino acids into your bloodstream for as long as eight hours, creating a longer lasting muscle-forming period. With the help of the whey protein isolate, hydrolyzed whey protein isolate, whey protein concentrate, calcium caseinate, milk protein concentrate, and micellar casein, the Phase8 supplies 26 grams of protein content used for muscle repair.

In addition, the Phase8’s flavors were formulated by the top protein flavoring experts. Customers agree that its taste is unbeatable, even when compared with the leading competitors. It also tastes great when mixed with water. No unnecessary carbs, like sugar, were added to make it palatable. It basically gives you a guilt-free, protein powder.

Another great thing about the Phase8 is that you are free to consume it any time, and still be effective. This allows for a continuous delivery of amino acids to your bloodstreem, even after your gym session. The long-release rate makes it an anti-catabolic and highly anabolic compound that promises a muscle-building environment for a longer time.

There are five different flavors available. This means you are not always stuck with the same flavor just to keep your muscles healthy and pumping. You are also free to choose among the six different tub size, which range from 2 to 4.5 pounds.


The flavor is one of the most heavily-regarded Phase8 top features. However, its texture is debatable. The powder tends to be thick and chalky. It is also very fine and light, making it difficult for you to mix without spilling bits of powder around you. Make sure that your ceiling fan is switched off as you scoop the powder out, or dust will be all over the place.

All the flavors are sweet. Vanilla tasted best, while the strawberry tasted like medicine, and the chocolate had a slight artificial taste. You can blend the powder into a liquid, but you will encounter some mixing issues as a sludge forms shortly after.

It also tends to become thick and difficult to swallow when added to milk, water, or juice, contrary to what the company stated on the product label. Lastly, the scoop is much bigger than the usual, but its size makes sense as the serving size is larger than the average.


The MuscleTech Phase8 protein powder is strictly for muscle-building and not for weight gain. Its slow-release formula allows you to continuously build muscle throughout the day. With so many flavors to choose from, you will surely look forward to try all of them. The only notable downside is its difficulty to mix with liquid, but it is, overall, a great muscle-building supplement that you can add to your daily routine.
