Our Signature BCAAs are packed with 7 grams of BCAAs in the optimal 2:1:1 ratio. This formula provides the essential amino acids—leucine, isoleucine, and valine—that your muscles need to reduce soreness, prevent breakdown, and support lean muscle growth.* Plus, added electrolytes in this formula keeps you hydrated and refreshed, so you can stay at peak performance.

Ingredients

Branched-Chain Amino Acids (BCAAs) (7 grams)
BCAAs consist of three key amino acids: leucine, isoleucine, and valine, each of which plays a distinct role in muscle health and performance.

Leucine: The Muscle-Building Trigger (3.5 grams)
Leucine is the most critical BCAA for muscle protein synthesis. It acts as the key activator of the mTOR pathway, which triggers muscle growth and repair. Leucine is unique in that it is not oxidized for energy during exercise but is used solely to stimulate muscle building. The 2:1:1 ratio found in BCAA supplements provides a leucine-dominant balance to ensure this process is effectively initiated.

Isoleucine: Energy and Muscle Recovery (1.75 grams)
Isoleucine supports energy production during exercise by promoting glucose uptake into cells. It also assists in muscle recovery and repair by helping muscles absorb and utilize glucose more efficiently. Isoleucine plays a dual role in providing fuel for workouts and aiding post-exercise recovery.

Valine: Endurance and Muscle Preservation (1.75 grams)
Valine acts as a muscle-preserving amino acid during workouts. It helps prevent muscle breakdown by providing an energy source for your muscles. Valine also plays a role in central nervous system function and can reduce fatigue during prolonged exercise, allowing you to push harder and longer.

Electrolyte Matrix (1.33 grams)
Our electrolyte matrix is carefully formulated blend of essential electrolytes that helps maintain hydration, support muscle function, and promote overall performance. Electrolytes regulate fluid balance, nerve signaling, and muscle contractions, making them critical for athletes and active individuals.

“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.

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.”
