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.

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
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
Price: Initially seems high but think about what you're getting for $40: like 20 solid meals (well not solid per-say). Yeah you could get a greater volume of chicken for the same price but think about it this way, have you ever run across chicken with creatine in it? Yeah. That would be weird.

Mixology: Haven't tried this in a shaker bottle; I always go straight from the blender. The verdict? Smooth. We're talking Sean Connery covered in baby oil smooth. Like a seal dipped in grease shooting down a water slide. No clumps in here. You find any clumps you can personally call me, any time of day, and day of the week, and work out your feelings. Maybe we can make up over a tall glass of chocolate weight gainer.

Taste: I see a lot of review on here getting down on the taste; it's a weight gainer not a jelly donut!!!! It comes in chocolate, vanilla, probably strawberry...if you want something crazy like orange sherbet...shut up. You're here to pack on Serious Mass®, not have a tasty snack. It's not supposed to taste good. They do that so only tough badasses use it.

Gains? You Betcha! Go from scrawny weakling to scrawny weakling+5 pounds in a month's time. Oh yea and you have to lift for it to work. Kinda sucks but uknow lol

Name: Serious Mass? Kind of false advertising if you ask me. The sun..that has serious mass. This is really only a few Kilograms so it seems like kind of an overstatement but like what do you expect typical Madison Avenue type scam job. I watch Mad Men. I know what goes on. Trust me.

I had trouble taking the recommended serving size because it killed my appetite. After couple days of trying to take the mass gainer and still eat my meals, I decided to use smaller portions. Now I make a shake with half the recommended serving size along with some protein powder, milk, peanut butter and flax seed. I also use a blender (not the blender cup).

Good protein at a great price. However, it gets a bit old after a while. I have found it hard to choke down shakes with this in it. Probably because it lasts so long, haha. Besides that, it's a solid protein powder. I am currently doing Crossfit and it is hard to take in enough calories in a day, this really helps. Oh, and the tub is so big. It's hilarious.

About me: Started consuming @ 174lbs, 6'1". Started consuming when starting my first solid workout program.

Reason for consuming: Hard time getting my 3500-4000 calories a day for bulking through meals alone.

Modus Operandi: Blended shake with 4/5ths of a scoop with 2 cups of milk, a cup of oats and 2tbsp peanut butter. 3 times a week (my workout days, more on this below). This has a total of about 1300 calories. (I bring my shake to my workplace. A dense, portable meal is the main objective of this product.)

Results: In a month I have gone up 14 pounds. Gained about 4-5% body fat. Squat went from 110lbs x5 to 195lbs x5 so far. Deadlift from 130 to 200lbs so far. Bench and Military press up about 20-30lbs or so (I have weak triceps). These numbers are starting to slow down, but with the power of calories I am still making gains.

Observations: Obviously I did not gain 14 lbs of pure muscle in a month. I got chubbier, but have also made great gains so far. I am stronger than ever, and I don't look horribly fat. If you are buying this then you are willing to put on fat, like me, in order to seriously increase your strength. Which I have done a pretty good job, imo.

Recommendations: ONLY CONSUME THIS PRODUCT IF YOU ARE WORKING OUT HARD! THAT MEANS COMPOUND MOVEMENTS ONLY. I put on a buttload of weight despite busting my ass in the gym. Now imagine if all I did at the gym were curlz, bench and those wussy isolation exercises. I would be way, way fatter and out of shape.
I would STRONGLY recommend following Rippetoe's "Starting Strength", my current program. If you follow correctly, you will chug down this drink without remorse -- you will need every single calorie for your optimal recovery.
