[This review was collected as part of a promotion.] I used Optimum’s Serious Mass powder to gain weight after a period of extended endurance training. I coupled with strength training and measured my weight, body muscle, and body fat daily. I saw consistent gains in weight and muscle mass, with some gain in body fat throughout the usage period. In addition to being highly effective, the vanilla flavor tasted great and I looked forward to a daily shake. I would highly recommend for anyone looking for safe & effective weight gain.

[This review was collected as part of a promotion.] This vanilla protein powder is exceptional. It mixes effortlessly and the taste is delicious, not overly sweet or artificial. It's a versatile addition to my daily routine, whether I'm making a post-workout shake or adding it to recipes for an extra protein boost. I've noticed a significant improvement in my energy levels and muscle recovery since using this product. The packaging is also convenient and ensures the powder stays fresh. If you're in search of a quality protein powder with a great taste, this one is a top choice. Highly recommended for fitness enthusiasts and anyone looking to meet their protein needs.

[This review was collected as part of a promotion.] The only thing I discovered is that if you use bottle water, it taste better and more like a milkshake. Otherwise I feel like the extra weight is coming on and will help with me adding weight on to turn into muscle or use it for a solid dad-bod.

[This review was collected as part of a promotion.] Optimum Nutrition is a very reputable brand in the bodybuilding/sport nutrition space. I have used their products before and know that they are made with quality ingredients designed for building muscle. I prefer to mix this powder with milk, because I like the consistency & taste better than water, but if you are lactose intolerant or don't have milk available, water will do just fine. I used a blender bottle and it mixes well with just shaking. This product is great to drink after a workout to feed your muscles with quality protein to maximize your muscle gain after a workout. This powder can also be used in smoothies or cooking. It is high in calories compared to a normal whey protein, and is meant for building mass, as opposed to a low calorie protein for lean muscles, so it's great for a meal replacement to give your body plenty of protein and calories for energy.

[This review was collected as part of a promotion.] I love this stuff. It mixes well and doesn’t feel too clumpy like a lot of powders. The taste is above average when compared to other similar products. I don’t feel overly bloated either. Overall I’d recommend this!

[This review was collected as part of a promotion.] I got this around a month ago and it is exactly what I’d hoped for. The pictures and description are spot on. I had looked for one forever and it was 100 percent worth it to pick one from this seller!

[This review was collected as part of a promotion.] I've tried quite a few different protein powders and some of them are terrible! Serious Mass is not one of them. It has a great taste to it and does what it's supposed to. I definitely recommend it!!!

[This review was collected as part of a promotion.] I am a 5’9 male and I’ve always struggled with putting on weight. I started with 1 scoop a day and later went in to 2 scoops. This product seem to work good. Mind that the benefits depend a lot on you general lifestyle, other good intake, exercises, etc. Just this supplement in not going to cut it. But if you pair it with the right amount and quality of sleep, stress, exercise, you will definitely do better results.

[This review was collected as part of a promotion.] Paired with my ultra intense training regime I have noticed significant gains while using this mass of seriousness. Mixing it with some sugar free chocolate syrup and a twelve ounces of milk has been a perfect combo. How much mass is too much mass? If you’re asking that don’t procede with this purchase🦯

[This review was collected as part of a promotion.] Let’s be transparent. I am 44 (m) 6’ 2” and was 165 lbs. I set out on a journey with Optimum Nutrition Serious Mass Protein Powder with the goal of gaining weight and developing muscle. In addition to 25 vital vitamins and minerals, this high-calorie weight gainer also contains additional creatine and glutamine for the best possible muscle repair. I was prepared to take on the challenge thanks to the alluring vanilla flavor and a huge 5.45 kg container that contained 16 servings. Let's begin with the advantages. The claim that Optimum Nutrition Serious Mass will significantly increase calorie intake is unquestionably true. It's simpler to achieve my daily calorie objectives thanks to the high caloric content, which is essential for weight gain. Additionally, the protein content supports muscle growth and regeneration, which improves my workouts and recuperation time. So far I have added pounds but have also been consistent with my workouts and I can notice a difference. Now I have not only taken a few years off, (haha) but have added lean muscle and its really noticeable. Key is get into the gym and be consistent. I will be buying another canister when this one runs out.

[This review was collected as part of a promotion.] I enjoy a nice workout to keep up wirh my health and also my appearance after getting a little older . I like that this Serious Mass is easy to mix with the simple instructions. I add mine to a blender bottle the wide picked up . It has a great taste and although loaded wirh protein it taste like ailk shake . It gives me that extra boost of energy I need to completey workouts.

[This review was collected as part of a promotion.] I've been looking for a bulk up vanilla protein that tastes great, and this fits the bill. It's got a combination of serious protein, fats and carbs for a complete bulk adding formula. Most other proteins are just that--protein. This full combination makes adding calories in a body building ratio a breeze. Highly recommended! Stop searching and make your life easier.

[This review was collected as part of a promotion.] This Serious Mass gainer was great. It mixed well and tasted good. I would take this for breakfast and it would last until dinner. I would recommend to anyone seeking a product like this. Big scoop and easy instructions.

[This review was collected as part of a promotion.] I'm not someone who does well with dairy, but I don't feel bad after using this in my smoothies. Hard to actually notice any weight gain on using this, but it does help fill me up in my meals. Filling, not bloaty afterwards.

[This review was collected as part of a promotion.] I workout on my lunch break every day so I mix up a serving of this in my mixer bottle to drink while I'm commuting to the gym. Since I don't eat much, if any during this break, this Serious Mass formula is perfect for me and my routine. It's high in protein, so it helps build muscle, high in carbs, so it gives me more energy and is high in calories to give me the calories needed to burn while working out. I would definitely recommend.

[This review was collected as part of a promotion.] My son and I both like taking this Serious Mass protein. The rich vanilla flavor makes it easy to take. I can mix it this just water and ice or with milk and it takes great. After about almost two weeks of taking it, I can say it helps with muscle recovery. My son feels it helps him after his high school baseball conditioning, he feels less soore and recovers faster. Easy to take, great taste and results you can feel and see.

[This review was collected as part of a promotion.] I got this for my son and it has really helped him bulk up for high school football. He has been in the gym and working out like a madman, but with rather slow results. and he's been getting discouraged. Since he's been taking the serious MASS shakes, he has been able to bulk up and is building muscle and strength FAST. He says that he loves the flavor when mixed with milk, but it's not so tasty when mixed with water. Plus it mixes super easy! It doesn't clump together like others that he's tried before, it mixes completely every time.
