Optimum Nutrition Serious Mass, Weight Gainer Protein Powder, Mass Gainer, Vitamin C and Zinc for Immune Support, Creatine, Banana, 6 Pound (Packaging May Vary)

This is my 5th time buying Optimum Nutrition Serious Mass, and it continues to deliver great results. It has really helped me maintain a steady calorie surplus and support my weight gain goals. The taste is consistent, it blends well (especially in a smoothie), and I like that it includes added vitamins like Vitamin C and Zinc. I’ve seen noticeable improvements in my weight and muscle size when using it consistently with workouts.

Optimum Nutrition Serious Mass is a great choice for anyone looking to gain weight, build muscle, or increase overall calorie intake. The Chocolate flavor mixes smoothly—especially if you use a blender—and has a rich, dessert-like taste without being overly sweet. Each serving delivers a very high amount of calories, protein, and carbs, which makes it ideal for people with fast metabolisms or those who struggle to eat enough throughout the day. It also includes added vitamins, minerals, and creatine for extra support. The bag is large and lasts a good amount of time depending on how much you use. The powder is heavy, so mixing by hand can be a bit difficult, but blending solves that problem easily. Overall, Serious Mass is effective for healthy weight gain and muscle-building goals. If you need a calorie boost and don’t mind a thick shake, it’s a solid and reliable product.

I purchased this item for my father, as he was looking to gain weight. We've used this brand before, and he's liked the taste, as well as the overall feel of it, so we decided to give it a shot. This powder is easy to use and incorporate into a daily diet. It's also packed with vitamins and protein, which is a nice bonus. The quality is also excellent. It dissolved easily in a shake, and also digests well. The texture is a little rough, though balanced and not too chunky when thoroughly incorporated, and overall, it is great. At $50 for 6 pounds, it's a bit pricey, but quality doesn't come cheap. I would recommend this product.

Would rather the chocolate cause the vanilla doesn’t taste good but it got the job done if you’re trying to gain weight. I started with one scoop cause 2 scoops is a lot

First of all, this is not your typical protein powder, this is for bulking. Each scoop has 625 calories, I have one scoop 3 times a day ( 1,875 calories total) instead of the recommended 2 scoops per serving; to me two scoops with 24 ounces of water is too much. It has a ton of protein and creatine per serving; two scoops give you 50 grams of protein and 5 grams of creatine. So far the results have been great with me gaining almost 5 pounds a week, obviously it’s not all muscle but again, this product is for bulking. I am on my second 20 pound bag and I am extremely happy with this product. If you are looking to loose weight or just maintain your current weight, I recommend either choosing a different product or having only one 625 cal scoop per day of this product, no more.

This protein powder is excellent! It mixes very smoothly with water or milk and doesn’t leave any clumps. The taste is really good, not too sweet, which I appreciate.

What they tell you. It tastes great and is a good supplement to build mass. What they don't tell you. Each serving consist of 2 huge heaping scoops of powder and 24 ounces of fluid (water or milk). This combination results in 48 ounces of liquid delight that they claim is a single serving. On what planet is 48 ounces a single serving? To put this in perspective, that is 2 full to the brim Shaker bottles that are intended to be consumed as one serving. 340 grams of powder from one serving translates into 3/4 of a pound of powder. Again to put this into perspective, the huge tub of powder you will recieve equals ONLY 8 advertised servings. The other thing they don't tell you is the powder is so fine and gummy that the only way to prepare the drink is to use a full sized blender. No Shaker bottles here. Preparing this mix is a mess. The powder is so fine that it creates a gummy mess that adheres to the side of the blender like Venom on Eddie Brock. Prepare to spend a significant amount of time coaxing the paste free to get it to properly mix. Great protein mix, but I sometimes I feel like it would be easier to eat 5 chicken breasts too reach the same calorie goal, than to put down 48 ounces. I realize that it can be broken up throughout the day, but so can multiple meals. There is also the option of using another protein supplement with a realistic serving size, multiple times a day. In the end, I feel like that is all they have done with this product. They have combined a multiple dose, throughout the day protein powder into a single serving, trying to advertise it as a solution that they obviously have not solved.

Great flavor, no stomach issues, and perfect after my workouts

Wysoka jakość. Bardzo polecam

Ok desu

MASS ITEM

I usually buy a chocolate flavor, so it’s the first time to taste a strawberry, And it was delicious

チョコレート味はとても美味しく、水だけで十分に飲めやすい感じ。使い始めたばかりなので、効果は使用後にまた戻ってレビュー聞こうと思います．
