Serious Mass, Weight Gainer Protein Powder, Mass Gainer, Vitamin C and Zinc for Immune Support, Creatine, Chocolate Peanut Butter, 12 Pound (Packaging May Vary)

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.

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.

Love this mass gainer, it’s helped me gain weight through my fitness journey. Tastes good and isn’t hard to dissolve

The product did exactly what it promised. I started out weighing 185 lbs; today marks nearly a month since I started (26 days to be exact) and I'm weighing in at 201.9. I just worked out and took the last bit of the shake, therefore I believe I will be somewhere around 198-199 after it digests. The trick in this product is to stay consistent throughout the process. The serving size is ridiculous! I only took on scoop w/ milk after my workouts and/or one scoop in the morning (mostly on rest days). Also, one scoop every single night before bed. As much as I tried to talk myself out of a shake before bed some nights, it seems to be the only time that I truly feel it working its magic. The good: Chocolate Peanut Butter tastes great. It is a very thick shake; even with one scoop. Mixes easily as well. The bad: After a while the flavor gets overwhelming. It was really sweet to me and I started hating the idea of taking it. Luckily it goes down very quickly. Overall, the product worked. With my 15 pounds I gained mostly size and very little fat in my face and mid area. My abs still show and I don't look chunky but I still trained my abs like normal so I would expect them to show. As for the fat in my face, I believe I will lose it rather quickly naturally so I'm not too worried. Remember that this is a supplement and not a substitute so if at any time it is possible, still eat a nice meal for results. Trust me, if you are like me, you will get tired of eating. Especially with a stomach full of a thick shake but its worth it. I do not think that I will order another one at the moment. I am happy with the results and will strive to maintain my current size. I will go back to the Whey Protein from ON. However, I would recommend the product to anyone that is active and serious enough to be consistent with this powder. I may give it another try if I decide to gain a little more in the future.

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!

Smooth taste Feel full No upset stomach

Super good

I have ordered this product for quite a while now. It's been as staple of my diet. However the main ingredient is maltodextrin. This is an extraordinarily high glycemic index ingredient and it also suppresses healthy gut bacteria. I would not recommend taking it if you have a family history of diabetes or if you don't take a pro/prebiotic supplement such as seeds symbiotic. I have also received multiple packages that are defective as they arrive with a tear in the packaging. One of them has odd clumping meaning I have consumed spoiled protein powder. Amazon refuses to give returns on products past 30 days so if you plan on stocking up on this product like I did test each package when it arrives as both of these companies obviously have a lack of care when it comes to working class people trying to gain weight on a budget. Calling this a budget item is being generous which makes it even more unacceptable to have received defective products that are supposed to last upwards of 2 weeks. I will amend this review if the company decides to send one replacement shipment as only one of the two defective products actually spoiled prior to my consumption.

Like the flavour.
