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.
