Serious Mass, Weight Gainer Protein Powder, Mass Gainer, Vitamin C and Zinc for Immune Support, Creatine, Vanilla, 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.

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.

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.

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

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

Great taste.

I am on a journey to increase my muscle mass and decided to combine two powerhouse supplements - Top Shelf King Maker and Optimum Nutrition Serious Mass. The results have been nothing short of incredible, and I can't recommend this combo enough to fellow fitness enthusiasts! The supp to combine with ON's serious Mass is Top Shelf King Maker ... it is an anabolic supplement for men to increase lean muscle growth and it certainly lives up to the claim. Its carefully crafted blend of ingredients is specifically designed to promote lean muscle development, and I've experienced remarkable gains in a short period of time. With King Maker, I felt an increase in strength and endurance, which helped me push harder during my workouts. Optimum Nutrition Serious Mass, on the other hand, is a renowned mass gainer that provides a substantial calorie and protein boost. It's a perfect complement to Top Shelf King Maker, as it offers the essential fuel my body needs for muscle growth. This supplement helped me hit my daily calorie and protein targets with ease, ensuring that I never fell short on the nutrients required to pack on muscle. The combination of these two products has been next level for me. Not only have I seen noticeable increases in muscle size and definition, but I've also experienced faster recovery times between workouts. This means I can hit the gym more frequently and maintain a consistent workout routine, which is crucial for muscle growth. One concern that some may have with mass gainers is the potential for unwanted fat gain. However, by using Top Shelf King Maker alongside Serious Mass, I've been able to maintain a lean physique while still adding mass. This is a testament to the targeted approach of King Maker in promoting lean muscle gains. In conclusion, if you're serious about gaining muscle mass and you want to do it the right way, the combination of Top Shelf King Maker and Optimum Nutrition Serious Mass is a winning strategy. These two supplements work in harmony to help you achieve your muscle-building goals, and the results are simply outstanding. I've never been more satisfied with my progress, and I owe a big part of it to this dynamic duo. Give it a try, and you won't be disappointed!

Serious Mass Pros: When you purchase Optimum Nutrition Serious Mass you really don’t have to purchase a multi-vitamin. Another benefit is that you will have no problem getting in your carbohydrate content with Optimum Nutrition Serious Mass. You get about 252 grams of carbs per serving – so this makes it really easy to get all of your carbohydrates in per day. The fact that it has so many carbs makes it really useful for a post workout mass building shake that also replenishes depleted glycogen stores. Another thing that I liked was that Optimum Nutrition added in BCAA’s, glutamine, and creatine. These are proven mass builders and will help with muscle growth and recovery. Last but not least – since this is a mass builder, it has to be stated that Optimum Nutrition packs in over 1,200 calories per serving. This will make it very easy to enter a calorie surplus if you are consuming 1 serving every single day. Serious Mass Cons: To be fair to you guys, let me preface this section by saying that this supplement has a lot more con’s than pros. Take a close look at this section before you spend your hard earned money on this mass building supplement. The first negative mark on this supplement is although it contains 1,250 calories per serving it only contains 8 servings per container. In the entire 6 lb tub you will only get 8 full servings! I think most guys are under the impression when they buy a giant tub that is 6 lbs. it will have close to 50 servings – but this is certainly not the case. Another major negative aspect that I noticed was that this entire container only has 400 grams of protein, or about 50 grams per serving. This may seem like a lot, but I took a look at the entire 4.2 lb. tub of combat protein powder and it contained a whopping 1,300 grams of high quality protein! Protein should be the main ingredient in any serious mass builder – but sadly the carbohydrates drastically outweigh the protein content. Most of the ingredients in this supplement are carbohydrates. Maltodextrin is a really cheap ingredient, and you can purchase a large 10 lb. tub of pure maltodextrin for less than 20 dollars! Another major check mark is that this has some major allergy warnings. Serious mass contains wheat, soy, dairy, and egg! These are the 4 most common allergens – so make sure you are careful if you are sensitive to any of these things. Last but not least – this product contains creatine, but ONLY 8 GRAMS in the entire 6 lb. tub. This is only 1.5 tsp and is barely enough to be noticeable. You are much better off buying your creatine separately and adding to your protein shakes, which is exactly what I do. Overall I’m going to give this popular Mass Builder a C. There are certainly better options out there, and I recommend making your own mass builder instead of buying this processed formula.
