SERIOUS MASS provides you with more tools to help you pack on pounds, when taken in addition to normal calorie intake and over time with regular resistance training. Brand Story By Optimum Nutrition

Review: lives up to its name - Serious Mass really lives up to its name. If you’re looking to put on size, this is one of the easiest ways to get a huge calorie and protein boost in one shake.. The taste is solid (I’ve tried Chocolate and Vanilla), though it’s definitely thick — I usually blend mine with milk or add a banana/peanut butter to make it smoother. It’s filling, so I don’t use it every day, but on heavy training days it’s perfect. The bag is big and lasts a while, though it can be a bit pricey. Overall, a great option if you’re serious about bulking and need extra calories.
Review: Best Purchase that Money can Buy - My most recent purchase from desertcart was the protein supplement, Optimum Nutrition Serious Mass. The reason I am writing this review (I usually don’t write reviews, unless the product is exceptional) is because I’ve found this product to be extremely helpful in my fitness goals. As a male in college, I don’t always have a lot of time on my hands. As you can imagine, college students often have varying and complicated schedules that require convenience and on-the-go products for our busy lives. But this product is definitely not only for college students but for people of all walks of life; people who need the right amount of nutrients and calories in a quick and convenient way that tailors to their schedule. I’ve been using this protein shake for quite some time now as this has been my fourth or fifth purchase. I wanted to wait for some time to see if this product does indeed have any positive effect on my fitness goals, so in short, Serious Mass by Optimum Nutrition does work. Who is this for? Serious Mass protein powder is for anyone looking to gain weight in a healthy, convenient, and safe way. It is for people who may need a boost in their weight due to their health situations, for lifters, bodybuilders, athletes, fitness enthusiasts and the list goes on. As for me, I am using this product to add on more weight when I go to the gym to lift and to increase muscle mass. Convenience Naturally, I have an extremely high metabolism. Since I am a hard gainer, to acquire more weight I need to eat a lot throughout the day. Because of time constraints and busy schedules, Serious Mass makes it easy to consume, essentially, a high-caloric meal. How much to use? The directions for this protein shake asks for a serving of two scoops; however, I have found this to be way too much as it is too chunky and thick even with the help of a blender. I suggest to use just one scoop as the scoop that’s included is very large with it being already about 625 calories. You can use this as a meal replacement but for optimal effect, this should be taken in between meals and before bed. Personal Experience I personally have found this extremely beneficial in gaining muscle. Within a couple of weeks to a month there are noticeable gains in muscle growth. As for taste, the protein powder actually tastes good unlike other brands; so far I’ve had strawberry and chocolate, both are very good. The only small issue that I have had with Serious Mass (along with all other protein powder supplements) is the need to use a bathroom relatively soon after consuming this product. As with many protein powder and supplements, it usually increases bowel movement. Then again it can be thought of as a small sacrifice to the greater benefits that are to come. Despite this review being quite lengthy, I truly hope that your goals will be met for whatever situation you try to achieve. As I have found this product very helpful; I hope that it too will benefit you all as well. Best wishes to your health and journey!

Tastes good, good ingredients, price is amazing. Good amount of calories per serving which is exactly what I need when the GLP-1s make me not hungry.
