Whey protein is the most important weapon in your muscle-building arsenal. It promotes muscle growth, counteracts muscle breakdown, and supports your workout recovery.*
Bonus: It’s also easy to digest and a source of powerful BCAAs.* Our Signature 100% Whey Protein combines three hard-hitting types of protein in one powerful blend. It’s perfect first thing in the morning, between meals, and especially after your workout. It’s so delicious, it’ll also slay that sweet tooth!
WHEY BLEND BREAKDOWN
WHEY ISOLATE
Great for low-carb diets, low in fat, and easily digested.*
WHEY CONCENTRATE
Concentrate has a more balanced amount of proteins, carbs, and fats to fuel your workouts.*
WHEY HYDROLYSATE
This whey protein has been hydrolyzed, or broken down into strings of amino acids called peptides, for even faster absorption than standard whey!*
DIGESTIVE ENZYMES
These enzymes help with the digestion of your protein.* In fact, they are clinically studied and shown to increase the uptake of amino acids into the blood by 20% compared to whey protein given alone.*
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.
