Product Overview Signature Mass Gainer

Signature Mass Gainer is a simple — and clean — way to go from skinny to stacked. It’s fully stocked with 810 calories, 67 grams of muscle-building protein, and 110 grams of carbohydrates. Probiotics help your body utilize the protein to its fullest. So, if you can’t seem to get enough mass-making nutrition in your day, skip the drive-thru and have a rich, satisfying shake.* Mass Gainer


We've put together a killer blend of high-quality protein sources to provide key muscle-building amino acids. The majority of the protein comes from clean, fast-digesting whey protein isolate. Milk protein concentrate and whey protein concentrate boast high bioavailability and supreme amino acid profiles. Casein rounds out the dairy proteins, providing a slow release of amino acids that supports muscles for hours.*


Carbohydrates are key for a mass-gaining diet. They provide your muscles and liver with the fuel you need to lift big and train hard. Maltodextrin provides fast-digesting carbohydrates while ModCarb™ and Cluster Dextrin™ provide slower-releasing carbs that have less of an impact on blood glucose levels.*


Fat is not the enemy! It’s a valuable tool for clean bulking. Our bodies need some fat to produce hormones, build cell walls, absorb fat-soluble vitamins, construct neurons, and carry out many other important functions.*


The probiotics in our Signature Mass Gainer have been developed specifically for use in powder supplements. Many other brands use standard probiotics and cannot guarantee that their probiotic bacteria are even viable. These specialized probiotics have also been proven in human clinical studies to improve digestive health and the uptake of protein. When you’re on a mass-gaining diet, a little digestive health support goes a long way. And, of course, protein absorption is crucial to making lean muscle gains.*

A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, was founded on a single promise: Trust. It’s who we are and it’s in our blood. Our Signature line is built on the same promise. Every product is no-BS, transparent, filler-free, and formulated with effective doses of research-backed ingredients you can trust. We create the highest quality supplements, so you can focus on leaving a mark of your own.


Signature products are formulated with high quality ingredients at effective doses that we’re proud to share with you. We don’t hide anything in a “proprietary blend”, so you always know exactly what you’re putting into your body.


An effective dose is the amount of an ingredient that has been shown to deliver results. Some supplement brands add a sprinkle of an ingredient just so they can say it’s in the product. Signature supplements always include enough to get the job done.


Trendy, flash-in-the-pan ingredients come and go. But time-tested, gym-proven ingredients are what you need to help you achieve your fitness goals. That’s what you’ll find in Signature products because that’s what works.

Tastes great and gets the job done. My only issue is with the packaging, not the easiest to open when it arrives and the scoop is rather cumbersome.

I liked this a lot. Number one because of all the different kind of proteins it has. The only thing I didn’t like and that I think you guys could change it’s the scope shape, I think It would work a lot better if it was like a cylinder

This Mass Gainer is amazing. First off, It tastes like a thick vanilla milkshake with the power of muscle-building protein. It has a great carb -protein ratio, It has probiotics. It keeps my muscles thick and full. I take 2 scoops post workout with organic whole milk,Creatine,Glutamine.Bcaa's all unflavoured and a multivitamin and fish oil. With Compound exercises in addition to this powerful post workout shake and other meals like Omega 3 eggs, oats, peanut butter, Whole grain spaghetti, spinach Extra virgin olive oil Atlantic Salmon I have put on healthy muscle mass. God bless you all

So... after checking many of the Mass Gainers here i picked this one for some reasons. One is because the types of proteins that are in this product (main source is isolate and the use of micellar casein no calcium or other inferior types). Second is because there are no vitamins here that interfere with each other like in other gainers. Taste is fine not amazing but good. Mixability is great in blender (havent try to mix 211g in shaker too much). 67g protein 810kcal adding to this banana and 2 tbsp peanut butter almond milk and youve got 1200+ calories !

2 months ago I bought 6 bags and today I just bought another 10 bags. Why..... because I like it. Good deal, tastes good, mixed well and good results. 2 scoops after workout that's good enough for me.

Every positive review on this must have never used another powder in their life. I decided to try this from my usual Optimum Nutrition Pro Gainer and will be switching right back. It's thick, doesn't mix well, the chocolate flavor is not awful but I've had many better. The 2 scoops is too much powder as well. Go with O.N Pro Gainer, trust me.

Years later I'm still looking for something comparable to's Ultimate Mass. To me it was by far the best around. I use these for meal replacements as an easy lunch at work so not for it's intended purpose. Two scoops is WAY too much and once does the trick to hold me over until dinner. Like all other protein/mass gainers I've tried since they discontinued the Ultimate Mass line, stay away from me 4 hours after consuming for at least a good 2 hours things get smelly. Please bring back Ultimate Mass!

Great mass gainer! Has a good taste and mixes well. Pretty straight forward ingredients list. Seems a little higher in protein vs. carbs when compared with some other products which I think makes it more advantageous.

Taste was great, mixed well with both water and milk. Results were great, definitely helped me add mass. The only problem I had with this is when I would mix my mass gainer with water after a workout, some powder would stick to the bottom corners of my completely dry shaker cup, and no matter how long or hard I tried shaking I couldn’t get that little bit to mix. Other then that this product worked great for me and will continue to buy bbcoms signature mass gainer!

Wow. Noticed a difference during the very first workout. And by the end of week one, some impressive results. Muscle size does look bigger for sures. Added sets and reps to everything. Plus no hangover from this stuff. Leaves you feeling clean and strong after your workout. Smells good, tastes good, mixes easy...even with a spoon. Just go light on your dinner meals and you won't lose any muscle definition while on this stuff. You can probably get by on 1&1/2 scoops before and 1&1/2 after your workout...depends on the look you want. Have fun.
