The Bigger Picture of Weight-Gain:

Serious weight gain requires serious calories. However, those who need the extra calories most, often have the toughest time consuming enough of them. For many aspiring to be bigger, highly-active metabolisms, weaker appetites and on-the-run lifestyles make consuming sufficient calories through whole foods alone a real challenge. With Serious Mass, you've got nothing to lose and lots to gain. We've consolidated over 1,250 calories, 50 grams of protein, 250-plus grams of carbohydrates, and 25 vitamins & minerals with added glutamine and creatine into every serving. It's time to stop thinking small; get serious - Serious Mass.

Beyond The Basics

1,250 calories per serving in water; 1,630 calories when made with low fat milk.
50 Grams of protein from a combination of faster and slower digesting sources including Whey, casein, and Egg.
250-plus grams of carbohydrates to support fueling of intense workouts and aid in the replenishment of glycogen stores - with NO ADDED SUGAR.*
Enhanced with Creatine, L-glutamine & Glutamine Peptides, Choline, Inositol, PABA, and MCTs.
25 Vitamins & Essential Minerals with an emphasis on B-vitamins and Antioxidants.

Muscle gain


Taste		Great flavor and overall great product for us hard gainers.
Mixes well		I usually pour in 8oz of milk first, then my 1 scoop, then top off with final 8oz. it usually mixes perfectly this way without getting large chunks of powder stuck to the underside of the shaker lid.


Taste		I have chocolate flavor 9 and 7 for strawberry because if I mix strawberry without a banana in milk, it taste like drinking some powdered tablet.
Taste		Make sure you add a banana to give a better flavor in strawberry weigh 2% milk.


Taste		just started to use this product couple weeks ago and feel really good and Taste also delicious .


Taste		I got my box thinking that it was going to be the best tasting product ever.
Taste		but nonetheless the taste turns off a higher score.


Taste		Taste great.
Mixes well		But sometimes when you mix it, there are clumps left in the bottom of the blender bottle and some clumps floating on top.


Muscle gain		1st time weight gainer user and got serious mass 10lb bag.
Muscle gain		but mostly fat lbs gained around my belly and the serving size is unreal way TOO BIG.


Taste		The taste is terrible and leaves you feeling really bloated afterwards,


Taste		ON Serious Mass.. really help me in my bulking phase... Used this from Oct 2013- April 2014, Flavor wise.. are great.. Chocolate Strawberry love it


Taste		I have been blending the powder with whole milk, a banana, and peanut butter, and it taste great.


Muscle gain		Great product, gained 20 pounds in 2 months with 12 lbs of serious mass.
Taste		the taste is also great, mixes just perfectly.
Mixes well		the taste is also great, mixes just perfectly.


Muscle gain		I needed to put on weight and gain mass; I am a 6'8" college basketball player with a very fast metabolism and it was impossible for me to put on weight.
Muscle gain		but long story short after adding this supplement to my diet I gained 20lbs of muscle in 6 months alone.
Taste		this supplement tastes great and you can mix it with anything.
Mixes well		I always mix mine with peanut butter and creatine and there are never clumps or nasty floaters.
Value for money		It's also really cheap for a 12lb bag and that lasts me a month or more


Taste		Great taste I mix in peanut butter and some chocolate chips in.
Value for money		The price is half of a competitor .


Muscle gain		Compare it to other mass gainers & only Universal Real Gains would be a better value even though its a little more expensive because it has twice the 25g of protein of SM if u cut the serving size in half.
Taste		Have used this mass gainer for a year & it works, does what it's meant to do, & it is probably the best value per serving on the market & the strawberry flavor tastes great!

Value for money		Best mass gainer for the price tied with Universal Real Gains IMO, quality ON product & will definitely buy again.


Muscle gain		Only reason it's got double the calories as many other gainers is because the serving size is twice as big.


Strength		I can honestly say that Serious Mass has made all the difference to my weight gain.
Taste		Great taste and excellent results.


Taste		Favorite mass gaining shake so far taste good and works.


Taste		The taste is incredible.
Taste		It really tastes like I am drinking chocolate milk.


Muscle gain		I had started using it after I had saw my friend one week at the gym then the next week he had gotten huge and he told me it was from serious mass plus he used to be bigger as he used to play football so he was explaining some muscle memory stuff.
Strength		but what I had been lifting had gone up by at least by 150% and I saw massive differences from when I started to then, granted I was working really hard spending hours in the gym
Taste		Anyway, get the Chocolate one, I heard the other flavors taste nasty, I don't know about that
Taste		but the chocolate one tasted good.
Value for money		Optimum Serious Mass, is my favorite protein shake, I had bought the 12lbs bag and thought for the price, there would be a high chance I'll be dissapointed
