I've just finished my 3rd bag (Over about 3 months) and went from 205 -> 220. Was hoping to end up around 235 but I'm married so I never get what I want.

Flavor Name: ChocolateSize Name: 12-Pounds Verified Purchase
With the size scoop this weight gainer comes with and the amount of calories per serving, I only use one scoop per serving which is half of the recommended serving. For someone who wants to put on mass quickly, I think this is the optimal amount as there is no way the human body will digest a serving of 1200+ calories. With that being said, the taste isn't bad at all, and for the price, it's the weight gainer to get if putting on weight is your primary motivation.

I would also recommend to anyone with these types of goals to also supplement amino acids separately to help with digestion and absorption and if your hitting the gym hard, definitely adding a natural test and gh booster like DAA; ★ 50% Off Sale Today Only ★ Pure DAA D-Aspartic Acid Powder (200 Grams - Over 60 Servings) ★ Optimize Testosterone Levels - Promote Muscle Growth - Increase Strength & Endurance ★ Try it 100% Risk Free(which is what I take) or even some longjack or trib to elevate hormone levels in order to use those extra calories build more muscle is not a bad idea at all.

Flavor Name: ChocolateSize Name: 3-Pounds Verified Purchase
Bought the 3lb size to test it out. Was a little taken back by the scoop size but I found that taking 1 scoop twice a day once in the morning and once at night is manageable. Put on 4 lbs and just finished the container, works really well for me compared to other products, will be ordering a larger size.

Flavor Name: StrawberrySize Name: 12-Pounds Verified Purchase
I was hospitalized for the better part of a month, during which I lost 30 pounds. I was lean to start with so I needed to gain the weight back quickly for a corrective surgery. My diet was restricted to easily digestible foods so fluids were the best option. I purchased Serious Mass after my weight was level even though I was getting 3000 to 3500 calories a day using Ensure Plus and other high calorie foods. When I added serious mass to my diet, I gain 15 pounds in 3 weeks.

I used strawberry flavor. It's not very tasty, so I added peanut butter, chocolate and used milk. I only drank a half serving a day which worked well. Definately use a blender to mix this stuff.

I recommend this product to anyone that needs to gain weight. It is low in fat, high in protein and nutrients so it is a great option for people trying to gain weight for health reasons.

Flavor Name: ChocolateSize Name: 12-Pounds Verified Purchase
I hit a plateau recently because I just couldn't eat enough to gain weight (I'm 6' 4", have a blazing fast metabolism, and exercise anywhere between 5 and 7 hours a week so I now consume 4000 cal. a day) and this stuff really pulled through for me. I'm up 5 pounds in 2 weeks and obviously it's not all muscle but I've always used the 1) gain weight, 2) lose just the fat, 3) repeat, method for body building and Serious Mass has been a huge help so far.

I couldn't tell you much about the taste. Once each morning and once after workouts I throw a scoop into a smoothie mixed with low fat milk, low fat ice cream, some vanilla extract, and various fruits (depending on what I'm feelin') so I don't know what it tastes like mixed alone in a cup of water or milk. The smoothie is delicious though.

I certainly plan on buying another bag when I'm finished (which might be a while because the bag is HUGE). Also, to brighten up my day, I took a black sharpie to the "M" in MASS and it puts a smile on my face every morning.

Flavor Name: ChocolateSize Name: 12-Pounds Verified Purchase
To begin, the serving sizes are unrealistic, I drink 1/3 of a serving three times a day with a mix of 1 and 1/2 cups of whole milk and water. The taste is mind blowingly delicious though (obviously the milk will do that) and I actually look forward to drinking it. I've gained about 3 pounds after using 3/4 of a bag, but more impressive are the gains made in the gym. For example, my bench press went from 185 to 225; about 160% of my bodyweight. The only downside I could think of is that the powder is as fine as the purest sand from the Sahara, the slightest nudge and your house looks like a woodshop.
