Muscle Support Formula

Preserve Muscle. Recover Faster. Perform Stronger.

Peptide 490™ is a next-generation muscle support formula created for athletes, fitness enthusiasts, and anyone committed to maintaining lean muscle and supporting recovery. Muscle insurance if you will. At its core is the clinically studied dose of 2.4g of PeptiStrong®—a plant-based peptide matrix developed through advanced AI-driven scientific research.

In human trials, PeptiStrong® has been studied for its impact on key areas of muscle health, showing support for recovery and preservation while supporting muscle protein synthesis and shown to influence myostatin levels. This innovative ingredient works in harmony with your body’s natural processes, providing support through periods of training, activity, or physical stress.

Whether you’re training intensely, pushing through demanding physical activity, or simply looking to protect hard-earned muscle during periods of stress, Peptide 490™ delivers comprehensive support so you can come back stronger, day after day.

Why Choose Peptide 490?

Clinically Studied Muscle Support

Powered by PeptiStrong®, a plant-based peptide hydrolysate from fava beans, discovered through AI-driven research and validated in clinical trials for its role in muscle recovery and strength support. Also, in human studies, PeptiStrong® was shown to influence levels of myostatin—a protein that naturally regulates muscle growth—providing additional insight into its potential to support lean muscle.

Recovery & Strength Support

In controlled human studies, PeptiStrong® has been shown to help improve strength recovery, reduce fatigue, and promote lean muscle preservation during training or reduced activity.

Additional Formulation Support

Enhanced with Apigenin™, Epicatechin, and AstraGin®—ingredients selected specifically to complement PeptiStrong® by supporting nutrient utilization, cellular wellness, and overall performance nutrition.  Epicatechin, a plant-derived flavanol, has been studied for its antioxidant activity and potential influence on muscle health through myostatin pathways.

Plant-Based Innovation

An intelligently designed, peptide-driven solution that delivers clean, plant-based support for modern training and recovery needs.

Whether you’re training hard in the gym, recovering from a demanding season, or simply aiming to protect the muscle you’ve worked for, Peptide 490™ is built to support your body when it needs it most—helping you stay consistent and ready for what’s next.
