When it comes to building and maintaining muscle, you've probably heard the same advice: eat more protein.
Protein matters. But eating protein is only the beginning.
Before your muscles can use the amino acids in protein, your digestive system has to break long protein chains into much smaller pieces that can be absorbed.
PeptiSignal Complex™ in MuscleSignal™ takes a different approach.
It combines enzymatically hydrolyzed plant peptides with fermented L-leucine to help efficiently deliver amino acids and provide an important nutritional signal for muscle protein synthesis.
The concept is simple:
Deliver. Signal. Build.™
DELIVER: Smaller Peptides, Efficient Absorption
Whole dietary proteins are large molecules made from long chains of amino acids.
Before your body can put those amino acids to work, digestive enzymes have to break the protein into smaller pieces.
PeptiSignal Complex™ begins that process before you ever take MuscleSignal™.
Through enzymatic hydrolysis, proteins from pea and fava bean are broken into smaller peptide chains that are easier for the digestive system to process.
Among the smallest peptides are:
Dipeptides: two amino acids linked together.
Tripeptides: three amino acids linked together.
Their small size matters because your intestinal cells have a specialized transport system designed to absorb many dipeptides and tripeptides efficiently.
Meet PEPT1: Your Body's Peptide Transporter
One of the primary transporters involved in absorbing small dietary peptides is called PEPT1, short for Peptide Transporter 1.
PEPT1 is located in the small intestine and transports many dipeptides and tripeptides from the digestive tract into intestinal cells.
You can think of it as a specialized doorway for small peptides.
Instead of every peptide needing to be completely broken apart into individual free amino acids before uptake, many dipeptides and tripeptides can enter intestinal cells through PEPT1. Inside the cells, most are then broken down further into individual amino acids before entering circulation.
This is one reason hydrolyzed proteins and small peptides are so interesting for targeted sports nutrition.
The protein has already undergone part of the breakdown process.
PeptiSignal Complex™ uses this peptide-based approach to provide a broad spectrum of amino acids in a compact, plant-based format.
SIGNAL: L-Leucine Tells Muscle It's Time to Build
Efficiently delivering amino acids is only one side of the MuscleSignal™ story.
Your muscles also need the appropriate nutritional signals to begin the muscle-building process.
That's where leucine becomes especially important.
Leucine is an essential amino acid recognized as an important nutritional regulator of mTORC1, a cellular pathway involved in muscle protein synthesis.
MuscleSignal™ provides 3 grams of added fermented L-leucine as part of its 5 grams of total amino acids per serving.
This creates a simple two-part strategy:
Plant peptides provide the amino acid building blocks.
L-leucine helps provide the muscle-building signal.
BUILD: Put Those Amino Acids to Work
Once absorbed, amino acids can be used throughout the body, including as raw materials for maintaining and repairing muscle tissue.
Combine that amino acid availability with resistance training and a leucine signal, and you're giving your body important nutritional components needed to support muscle protein synthesis.
That's the idea behind:
Deliver. Signal. Build.™
DELIVER
Hydrolyzed pea and fava bean peptides provide smaller peptide chains and a broad amino acid spectrum.
SIGNAL
3 grams of fermented L-leucine help activate mTORC1 signaling associated with muscle protein synthesis.
BUILD
Amino acids provide nutritional building blocks to support muscle maintenance, recovery, and growth when combined with resistance training and proper nutrition.
18 Amino Acids Without Another Heavy Protein Shake
Traditional protein powders often rely on a large serving of intact protein.
MuscleSignal™ takes a more targeted approach.
PeptiSignal Complex™ provides a broad spectrum of 18 amino acids from plant-derived peptides and added fermented L-leucine.
And it does so without requiring another large 25–30 gram scoop of protein powder.
That can make MuscleSignal™ particularly useful when you want targeted amino acid nutrition without adding another shake or meal.
Why This Matters More As We Age
Maintaining muscle becomes increasingly important with age.
Over time, the body can become less responsive to the signals that stimulate muscle protein synthesis. That makes resistance training, adequate nutrition, recovery, and sufficient amino acid intake increasingly important.
Rather than simply focusing on more protein, MuscleSignal™ focuses on providing targeted muscle nutrition:
Small plant peptides for efficient digestion and absorption.
18 amino acids to provide a broad spectrum of muscle-building nutrients.
3 grams of added fermented L-leucine to help provide the mTORC1 signal.
For adults who want to stay strong, active, and capable as they age, protecting muscle isn't just about appearance. Muscle supports strength, mobility, physical performance, and healthy aging.
Who Is MuscleSignal™ For?
MuscleSignal™ is designed for adults who want to make muscle health a priority, including people over 40, active adults, resistance-training athletes, people managing calorie intake, and anyone looking for a convenient plant-based approach to targeted amino acid nutrition.
It's not intended to replace whole-food protein or resistance training.
Instead, it's designed to complement them.
Don't Just Feed Muscle. Give It a Signal.
Building and maintaining muscle isn't simply about consuming the largest amount of protein possible.
It's about giving your body the right nutritional building blocks and the right signals to use them.
That's the thinking behind PeptiSignal Complex™.
From smaller plant-derived peptides, including dipeptides and tripeptides that can utilize specialized intestinal peptide transport systems such as PEPT1, to 3 grams of fermented L-leucine supporting mTORC1 signaling, MuscleSignal™ takes a targeted approach to muscle nutrition.
Deliver the building blocks.
Signal the muscle-building pathway.
Give your body what it needs to build.
