The Optimum Nutrition Serious Mass Weight Gainer is a powerful supplement for those looking to gain weight and muscle.

The strawberry flavor is tasty and not overly sweet, and it mixes easily without clumps. This 6-pound tub provides a good value for those looking to boost their calorie intake. Perfect for those who struggle to gain weight or need a convenient way to pack in extra nutrition. ... show more

  • I gained about 10 pounds
Flavor Name: Strawberry Size: 16 Servings (Pack of 1)
I gained about 10 pounds so far since I bought this. I take 1 scoop with milk per day every other day in my 24oz electric shaker and drink it as I do my lifts. Still on the first bag but I am already 10 pounds heavier and it looks like it didn't all just go to my gut either. This stuff works good if you are skinny like me and pair it with other sources of protein (real food and protein snacks). I am 6 foot tall and went from 135lb to 152lb, I started taking this at around 140lb and still have a decent amount of the first bag left since I only take half portions every other day with milk. The taste is pretty good its like strawberry milk but I will say you have to turn your electric shaker or blender on a bit longer because its so much powder otherwise you will get chunks. I don't have chunking issues with other powders in this electric shaker but I think its just the sheer amount of powder thats the problem and you will get that with any of these mass gainer products. ... show more

Flavor Name: Vanilla Size: 8 Servings (Pack of 1)
This protein is very good, I drink it every morning, it gives me incredible energy. It melts easily, it's really soft and delicious at the same time. If you put it in liquid, you'll add milk or just enough until it melts easily and doesn't form lumps, which is one of the reasons I like it more. It is very effective and gives fast results It's a very good mix. ... show more

  • Taste and quality.
Flavor Name: Vanilla Size: 16 Servings (Pack of 1)
This product has a good quality and perfectly homogeneous mixture. However, it’s very sweet which makes people unwilling to drink it. It’s very expensive nutrition for gaining weight even though it gives a good amount of energy and feels effective.

  • Best Purchase that Money can Buy
Flavor Name: Chocolate Peanut Butter Size: 16 Servings (Pack of 1)
My most recent purchase from Amazon 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! ... show more
