Serious Mass, Weight Gainer Protein Powder, Mass Gainer, Vitamin C and Zinc for Immune Support, Creatine, Chocolate, 12 Pound (Packaging May Vary)

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.

Great product for the money. It mixed well it's loaded with calories and carbs. Tastes great. It did what it was designed to do so if your looking to add some lbs on the scale this will work just fine.

Optimum Nutrition has consistently produced some of the highest quality whey products I've used. Easier to stomach and better tasting than competitors. Dissolves well in water as well as milk when mixed properly. I've used the product for years and it has served as an effective compliment to my workout regimen.

Tastes good and delivers great macros however the quantity you need to consume a single serving is massive If you want to blend two heaping scoops, which is one serving, and want to drink something that's less solid than concrete, you'll need to drink 5 or 6 pint glasses of this stuff. This isn't a quick, easy, dense way to get 1500 calories. It's a tremendous effort. I'm sure the ON mix is cleaner, but you can get easier calories with a 16" steak and cheese sub, and be less full.

Ok so I have been using this product for over a year now. I cycle it in bulking and cutting stages with a pre-workout (Cellucore C4 Extreme) and attempt to consume healthy food in addition to the product. I am an amateur with no professional experience, but this product has worked for me. I am a skinny guy with a very quick metabolism. I train for endurance and strength, NOT mass. If you are a skinny person who has trouble gaining weight I recommend giving this a shot. This is not for body builders who count calories and want to stay lean. Its a weight gainer! I am currently 5'10, 170 lbs. During this cycle I am training 3-4 days a week between 60-90 mins per workout. Like I said I train high endurance and strength, not heavy lifting. In the last 3 months I have gained 15 lbs and lowered my body fat percentage by 4%. I consider this a substantial achievement as I have never been able to put on weight unless I gain lots of fat. When I was cutting I used this as a meal replacement with low calorie intake and actually lost weight taking it! RATIO: The great thing about this product is you can tailor the servings to meet your needs. If you desire more calories and carbs, use more, if you start to notice your getting fat, use less. Start with 1/2 serving a day and increase as needed to reach your desired goals. I generally consume a 1/2 serving mixed with 4-6oz of fat free milk within 30 mins of working out in the morning. I then eat high protein foods throughout the day (Cottage cheese, Greek yogurt, oatmeal (rolled oats, not that instant crap), chicken breast, tuna, brown rice, etc). I try to eat as much clean food as I can throughout the day. I then have another 1/2 serving with milk in the afternoon. TASTE: This product tastes amazing. 1/2 serving mixed with milk comes out like a milkshake, not too thick, not too thin. If you go for the full serving it is very thick and heavy. Its hard to drink that much without throwing up. Split it up into 1/2 servings throughout the day. SIDE EFFECTS: I personally have major gas from this product. Its not horrible, but I have to leave the room throughout the day at work. I anticipate this and take breaks. No big deal. I have had normal bowel movements while taking this product, but I do consume high fiber oatmeal to assist with the digestion. I find myself dropping bricks if I do not consume enough fiber with this product, again, adjust the servings to fit your body needs. FINAL THOUGHTS: Overall I enjoy this product. If you use it as a meal supplement during your cutting stages you may notice you actually LOSE WIGHT while taking this product. I sure did.

Good chocolate flavor. No weird taste. Blends nicely with milk or water (milk is better). Nice nutrient profile with protein as the main factor.

Good
