Optimum Nutrition Serious Mass Weight Gainer Protein Powder, Vitamin C and Zinc for Immune Support, Vanilla, 12 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.

I've been using this protein shake for about a couple of weeks now, and overall I’m really satisfied with it. I usually take it after workouts or sometimes as a quick meal replacement, and it’s been working well for me.

High in cholesterol,but youre trying to gain weight and put on mass quickly in addition to your solid diet!! Before purchasing any supplement I would recommend you read the ingredients accordingly and look up any ingredients or all that youre not familiar with to get an understanding of what youre putting in your body. ON makes great supplement products and have been using them for over 4 years! I dont use the recommended 2 scoops I use 1 (with whole milk) and thats good enough to make a nice thick shake like consistency and I dont need ALL of those calories at once (over 1700 with whole milk) and getting half of the calories and half the over 140mg in cholesterol (about half your daily suggested cholesterol intake) is just fine for me! I also feel using the recommended 2 scoops (even with water) would make for a sandy thick wet cement like consistency! This WILL help put on the calories for you to GAIN as long as you workout and eat your daily meals. I will say the vanilla tastes VERY GOOD (being you like vanilla) and mixes fairly well if you have the proper shaker cup and do a little workout with it. Make believe youre a paint can mixer and blend it up! There will be some chunks of powder,but this is expected especially if you use 2 scoops. Also has a somewhat sticky/unpleasant consistency if on your fingers or a counter top and it gets wet. Taste 4.5 Effectiveness 4.5 Ingredients 3 ( I suggest YOU read the ingredients which you can if you zoom in on the product on Amazon) Though I give this 4 stars and I my self consume this stuff and I do like it I alsoI highly recommend you get your nutrients and calories from SOLID FOOD! Its much more effective and MUCH better for you

I’ve been using this protein for years. Overall, with powerlifting and this, I’ve put on about 50 lbs. Recently I’ve lost 5 lbs due to nursing school (exhausted, less money, very busy). I have been trying different protein powders which I also liked, but after seeing the weight on the scale today, I’m back. I prefer the vanilla, because it can go in more smoothies or you can buy multiple coffee syrup flavors and add them to change it up. This time I’ll be having vanilla and brown sugar cinnamon. Excited to be working towards my goal of 150 lbs again now that I’m about to get my life back lol

Love the product been using it daily for about 5 years now. I hate how they changed the packaging and now it just spills everywhere when transferring from bag to jar

I'm try to gain weight so seen many positive reviews. But everyone is different in body chemistry. I took the advice of several reviews and started with 1/2 a portion, I put the milk in a large glass then poured the powder in & used my blender stick. It was very smooth & tasted like a melted vanilla milkshake & was so sweet, I had to force myself just to drink the half mixture. It is very sweet & filling. Tried it for 3 days & was so filling it was difficult to eat any food. So I stopped & took a break & will try 1/4 a recipe until I can stretch my stomach. I cant possible imagine drinking a full recipe without throwing up. It is supper sweet.

With weight training and a very physical job I need a ton of calories (around 4000 a day) this mass gainer definitely helps, I find it tastes better with semi skimmed milk than water, and totals more calories consumed with 2 servings. The scoop is quite bigger, larger than what you'd used you put detergent in your washing machine, and the dose is 2 a day, you could just have one after a workout, but I have one at work around 10-11am which helps feel a gap well and being a shame is easier than food or snacks. I got the vanilla one, it tastes a tad different to the normal whey protein by ON, sweeter maybe but after a first few tries it's fairly nice, I don't use a blender just a shaker ball, and about 600ml of milk, it does a clump a bit and needs several shakes between a few swigs. Put the milk or water in first (this is common knowledge) but try and shake it hard/drink quick after dropping the powder in as the longer it fits the more it'll clump at the bottom and it's not fun trying to consume the gloop at the bottom, messy. Or just don't be lazy like my and blend it, might come out better.

using this one for years now. for me it works perfect. am even mixing it sometime with fresh fruits to make a smoothy.

Het is alsinds lekker en zeker effectief aangezien ik toch wat extra kilo’s erbij heb gekregen

This is complete waste of money on Mass gainer just have 8 servings in 5 pond box rather one should buy whey and make a bulking banana or fruit shake but this is waste

Che dire? Dopo aver provato molti prodotti di diverse marche, mi sono convinto che era arrivato il momento di testare le 'Serious Mass' della Optimum Nutrition. Mi alleno 6g su 7 la settimana, le prendo tutti i giorni perché a livello calorico ti riempiono la giornata e ti permettono di allenarti nella maniera più consona. Il gusto vaniglia è perfetto se lo si mischia con il latte, o facendo dei frullati, inoltre dentro la scatola si trova il misurino per dosare bene il contenuto. Subito dopo la prima settimana si vedevano i risultati prefissati, aumento di massa muscolare ben visibile, il mio corpo aveva ripreso brillantezza. Al momento il miglior prodotto che offre il mercato.
