Bodybuilding.com Signature Series

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.

Signature Series

We created our Signature line of products because we believe it shoudln't be a workout to get the highest quality supplements without paying the highest prices. As a trusted fitness brand, we've been delivering top-quality products to aid your fitness journey for over two decades. We don't take shortcuts and we don't make excuses, so you can trust that every Signature supplement is filler-free and formulated with effective doses of research-backed ingredients. Bottom line: We're crushing it so you can go crush your personal goals.
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.

Whey Protein

Our Signature 100% Whey Protein combines three different sources of whey protein in one powerful blend:

Concentrate has a more balanced amount of proteins, carbs, and fats to fuel your workouts.*
Great for low-carb diets, low in fat, and easily digested.*
This whey protein has been hydrolyzed, or broken down into strings of amino acids called peptides, for even faster absorption than standard whey!*

Whey protein is the most important weapon in your muscle-building arsenal. It promotes muscle growth, counteracts muscle breakdown, and supports your workout recovery.*

Signature 100% Whey has an impressive profile of 13 grams of isolate and 6 grams each of hydrolysate and concentrate. That means you have a lot of clean, quick-digesting, low-carb protein, with just enough whey concentrate for a creamy flavor and texture.

Pre-workout

Signature Pre-Workout includes proven ingredients that promote intense pump and growth while battling fatigue, so you can work out harder and longer. With 200mg of caffeine, this is perfect for high volume lifts, cross-fit, cardio or intense strength training. Taking a mega dose of stimulants isn’t always the best before your training so we focused this formulation on high quality, proven, efficacious ingredients to help you hit your training goals and make every workout count. Using this formula before training will help provide energy and get you focused to get the most from your workout.*

One of the keys to a great workout is a great pump. The amino acid L-Citrulline contributes to your body’s production of nitric oxide, a vasodilator. When your blood vessels are dilated, your body is more effectively able to circulate oxygen and other performance-maximizing nutrients to working muscles.*
The amino acid L-Leucine is known as a trigger for muscle protein synthesis (aka muscle growth) and a fuel source for your hard-lifting muscles. Your body cannot make L-Leucine, so it must come from supplements or food.*
Beta-alanine acts as a buffer between fatigue-promoting lactic acid and your muscles by producing carnosine, which keeps lactic acid in check during intense workouts. That means better muscular endurance, more energy for high-intensity or explosive movements, and better overall workout performance.*
Caffeine is one of the most common pre-workout ingredients because it works. Supplementing with caffeine has been shown to increase focus and improve workout performance, allowing you to dig in and get the work done.*

BCAA

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 BCAA because that's what works. Made up of three essential amino acids — leucine, isoleucine, and valine — BCAAs promote growth and recovery. We’ve included them in a 3:1:1 ratio, compared to many other BCAA products' 2:1:1 ratio, because of leucine's superior anabolic potential.

Take 30 minutes after your strength training to support muscle recovery. You can also mix with water and sip on this throughout the day for enhanced recovery support. This high-quality, affordable BCAA formula dissolves easily in water and fits with any nutrition plan. Made up of three essential amino acids – leucine, isoleucine, and valine – BCAAs promote growth and recovery.

Greens

Getting full servings of all the necessary fruits and vegetables every day can be a challenge. Make your life easier by getting full servings of ingredients like broccoli, artichoke, wheatgrass, and more with Signature Greens.

Ingredients like wheatgrass, chlorella, and spirulina are called superfoods for a reason. These ingredients and many others in Signature Greens bring with them a healthy serving of antioxidants. During normal function of the body, free radicals are released that can cause chaos inside your cells. Through ingestion of antioxidants like those found in Signature Greens, you can help support your body’s defenses against these free radicals and keep everything on track for your fitness journey.

CLA

Vitamins and More

A healthy digestive system means better breakdown of food. Your intestinal flora, or the probiotic bacteria living in your intestinal tract, are also a crucial part of your immune system. Signature provides the clinically studied amount (10 CFUs) of three proven probiotic strains. Specialized packaging keeps them alive and effective without refrigeration.
Signature CLA supports your metabolism and helps your body use fat as fuel—without the use of stimulants. CLA is an omega-6 fatty acid that is found in meat and dairy, but you have to eat a lot of both to reap the benefits. Signature CLA distills those omega-6 acids into an easy-to-take supplement.
