What Are Peptides?
Peptides are short chains of amino acids — between 2 and 50 — that function as signaling molecules in biological systems. Their small size allows them to bind specific receptors, making them a focus of research into targeted cellular communication.
Why Peptides Matter to Researchers
Published studies show endogenous peptide levels decline with age — a pattern linked to changes in cellular signaling. This decline is a major area of investigation across longevity, metabolic, and regenerative research.
Peptides vs. Traditional Compounds
Supplements
- Broad mechanism of action
- Variable bioavailability
- Often degraded in GI tract
- General pathway modulation
- Dose-dependent off-target effects
Peptides
- Receptor-specific binding
- High selectivity at low concentrations
- Defined amino acid sequences
- Endogenously derived structures
- Reproducible in laboratory settings
