Optimum Nutrition Serious Mass Protein Powder, 2.73 kg, 16 Servings | Strawberry, High Calorie Mass Gainer with Vitamins, Creatine and Glutamine, Supports Muscle Building

Best tasting best mixing best mass gainer IMO. After years of trying diff mass gainers out I always come back to this one. Tried most flavours but my favourites are strawberry, choc peanut butter and banana. Gotta love it

Good quality

It's helping me put on weight. I added a tablespoon of peanut butter and a banana, tastes really good with the strawberry one. This seems to be the best mass gainer, I've looked around and this is always said to be the best with approved ingredients. It is sweet tasting but if you add some peanut butter it will tone down the sweetness. I'm just doing pushups, ab crutches, planks and dumbbells. I don't go to a gym. With noticeable growth to my arms and chest, just started working on abs to balance it out. I only started to see results after drinking this stuff. Good price on this bigger bag so I think I'll get this one again in the future.

I have been using this product now for about a month and a half, i have seen some good results, this is also along with a 5k-7k kcal diet. I have bought multiple tubs of this from Amazon and a coupkle of 5kg bags. I only bought Strawberry and one thing i have noticed is the taste various from batch to batch, now this is to be slightly expected due to t he manufacturing process on mass, but today i have recieved a new 5kg bag and the colour of the powder is completely different. My usual Strawberry flavour is like an off white colour and then when mixed with milk/water it turns a pinky/red colour. This powder pre mixing is bright pink and smells different to any others i have had. I am starting to think that sub par protein maybe being sold in an exspensive wrapper. I mean when you buy a mars bar you expect it to look and taste like a mars bar....right?! not an imatation of the real deal!!! Anyway something to look out for folks.

This protein powder is an excellent for anyone serious about gaining mass. The large size offers fantastic value, and the mix is effective and potent. It mixes well, taste good and is essential for hitting those high-calorie and high-protein goals. Highly recommended for fast, reliable results!

I'm struggling to gain weight very bad, I'm 1.80 meters tall and 30 yrs old and my metabolism is crazy, I put hard weight and is fair to say I dont eat too much as well, just 2 meals a day, sometimes only one but I've decided to change that and after reading alot of reviews of top mass gainers, I have decided to try this one. So I ordered myself the strawberry 5 kg bag along with a blender and I'm following the next plan: I am spliting the serving in 2: one in the morning and one in the evening before work. I put 350 ml whole milk, 1 full cup of proteins(~170 grams), 2 big spoons of peanut butter, I'm adding 5 more grams of creatine , 50 grams of oats and 1 banana for flavouring and must say the taste is amazing and the vascosity is not too high, is drinkable. Have managed to drink it whole after 20 mins after breakfast. This combination will give you around 1200 calories per shake, so 1200 calories in the morning and 1200 calories in the evening. Thats 2400 calories just from the shakers! For meals I will try to eat as many eggs in the morning with a salad and for dinner one piece of chicken breast with potatoes and salad. Inbetween meals I will eat 2 snickers, 2 kinder bueno bars and 1 croissant 7 days. By my maths, with the shake combination and meals and snacks, I will have around 4000 calories per day intake, my goal is to get 10 kg in 1 month and 10 days. Today is day 1 and I weigh 64 kg, will update you next week on my current weight!

I only use this brand of mass gainer… reason being it sits will in my digestive system, it definitely does what it supposed to do. I have used other brands, cheaper brands but they do not pack the punch this do 💪 I have literally been buying this for over 10 years now & will never use other cheaper products. Yes it’s expensive but quality costs money simple! It mix fairly well. The ingredients are of high quality. In my opinion you will not be disappointed & like I said you will definitely be getting the performance you want. I packed on good quality weight… 2st in 3 months but that’s training 5 days a week keeping meals healthy. Hope you find this review helpful.

Great product, tastes banging. I tend to do one scoop rather than two to get my calories up at the end of the day if I'm falling short

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.

très bien, le gout est pas trop mal fait

Ottimo prodotto lo consiglio

El producto funciona de maravilla. Es para delgados que quieren subir de peso. Un buen entreno extenuante de fuerza hasta el fallo e inmediatamente después te metes esta barbaridad de 1200kcal y el musculo reacciona y crece. Cuesta de disolver. Yo lo mezclo, lo dejo reposar 10 - 15 min y vuelvo a batir y me quedan pocos grumos que masticar. El sabor es bueno.
