When it comes to nutrients that are essential to life and health, protein is the jack of all trades. It plays many roles in the body, such as a source of energy, helps prevent disease and infection, and repairs damaged tissue.
While protein is abundant in foods, meats, eggs, fish, dairy products, legumes, seeds, and grains, it is also available in supplements or protein powder.
Consuming protein drinks is a useful way to boost your protein intake. They come in different flavors, are convenient, and portable. You can take protein powders by simply mixing them with water or a liquid of your choice.
One of the most well-known protein powder brands you can buy is from Muscle Milk, particularly its Muscle Milk Pro Series 50. In an lb5 canister of this Muscle Milk Pro Series powder, it can help support muscle growth and muscle rebuilding.
If you’re interested to know more about the Muscle Milk Pro Series 50, keep on reading. Based on our firsthand experience, we will walk you through the key ingredients of this product and its benefits to help you decide whether or not it’s worth buying a lb5.

What Do People Say About It?
Lift – Run – Stretch reviewed the Muscle Milk Knockout Chocolate Protein Powder on YouTube. He said, “Just know that these are all milk-derived protein sources for you and that they are just going to help your body recover and also help you build some strength as well as long as you have obviously a workout routine going.”
“If you’re lazy, do not take this. You’re just gonna gain excess weight,” he added about the Muscle Milk Pro Series 50.
BIG PIN also reviewed the product, although he purchased the 32grams strawberry flavor.
“My experience on this is that I like this product a lot. It helped a lot with my size as well as my strength, but I took this a while back and I only took it for about two months. [Nevertheless,] I saw a lot of changes in my workout as well as how I look. It was very helpful,” he said.
One customer shared through Amazon about his experience with the Muscle Milk 5-Pound Pro Series.
“I read that they recently changed the formula and many people are saying it is harder to mix enough to get out the lumps etc. I have to admit, when I got my first jug of the new formula, they were right. It is harder to mix thoroughly. But I’ve experimented and have found a new and much better way to mix it. I have no problems with the following method.”
Another Amazon customer reviewed the Muscle Milk, saying, “My muscles knot up a lot and just plain hurt. I have a physical job and stay very active. I drink 1 16 oz glass of this a day and my muscle pain goes away also this has a lot of vitamins and minerals.
I have been out on my e-bike and my muscles were hurting a lot. I had a glass of this muscle milk and no more muscle pain. The taste is very good. [It’s] similar to a very good chocolate cake batter. “
One Reddit user posted, “I love the Muscle Milk Pro Series 50 Gram Protein Powder.”
However, in another thread that discussed whether the Muscle Milk Pro Series Protein is good over other protein powders, someone answered “There was a dude on r/fitness [physical fitness community] who had a lab analysis done on all the commercial protein powders and muscle milk scored really low.”
Final Thoughts: Should You Buy it?
Drawing from our experience, if you follow a workout routine, recovering from an injury, or have just started a workout program, you can consider taking the Muscle Milk protein powder.
Per serving, it contains essential amino acids, such as Leucine that play an important role in muscle building. It also contains calcium and vitamin D for healthy bones.
Our team discovered through using this product that this Muscle Milk product is also good for those who pursue a vegetarian lifestyle since they most likely eliminate common sources of protein from their diet, including fish, chicken, and meat, egg, and dairy.
