How is MuscLean Different?

While other competitor weight gainers use high amounts of low quality protein, carbs and fat, MuscLean focuses on quality protein...the same protein that is in their popular Protizyme. This has the unique ultra-microfiltration and digestive enzyme coating processes, which makes MuscLean stronger and more effective at building muscle than any other weight gainer on the market. It delivers the highest bioavailability per serving, loaded with essential fats, enzymes and recovery focused ingredients, nothing is more effective than putting on lean muscle than MuscLean. Plus with the lower carbohydrate, you are not going to feel bloaded and tired like with other products.

Protizyme Vs. MuscLean

One common question is why choose MuscLean over Protizyme? The main difference between the two supplements is the addition of essential fatty acids and oil in MuscLean. These were specifically added to help increase overall muscle strength, your recovery times and muscle building over longer periods of time. It was designed for the bodybuilder.


Post-Workout: Take MuscLean within 30 minutes of your workout. Take 1-2 servings depending on your muscle mass goals.

Anytime: Take 1 to 3 scoops of MuscLean to reach your muscle building goals throughout the day.

There are no stimulants or hormone-related ingredients so it can be stacked with anything, taken anytime during the day and can be used by both men and women.
