Product Overview

Bodybuilding.com 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.*

PROTEIN

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

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.*

fats

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.*

probiotics

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, Bodybuilding.com 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.

TOTAL TRANSPARENCY

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.

EFFECTIVE DOSES

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.

RESEARCH-BACKED INGREDIENTS

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.

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 Bodybuilding.com'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.

Bought 2 of these at 25% off recently, and if you like at price/serving alone it’s a pretty solid deal as far as mass gainers go. In terms of macro breakdown, I really like it. It’s high in carbs and protein and low in fat, which is nice for a lean bulk. Taste-wise, it’s pretty good if you mix with milk or water, although it can have a very slight chalky taste, which is tough to eliminate when you’re using huge scoops like with a mass gainer. Relative to some other gainers I’ve tried, the taste is great and I can usually chug the entire shake in around a minute. Definitely would recommend blending though, tougher to mix in a shaker bottle. It’s also pretty easy on my stomach compared to other mass gainers, some of which just straight up gave me the runs almost without fail. Could be due to the “probiotics” they add, but either way the result is achieved. Haven’t been tracking weight too well, so I can’t say if I’ve gained or not, but will be back to update (hopefully). Question for BB: Best to take this pre/post workout? Would use for carb loading beforehand, but not sure what is optimal for body to absorb. Thanks!
