Peptides are small chains of amino acids that act as signaling molecules. They can:

• Signal tissue repair and inflammation control
• Act on hormone pathways and cellular function
• Be synthesized for targeted therapeutic use

Quick links: Safety tips • Sourcing guide

They often bind receptors to trigger cascades that increase protein synthesis, immune response, or metabolic effects.

• Muscle & repair: stimulate collagen or growth factors
• Immune modulation: short peptides can alter cytokine profiles
• Metabolic: some peptides influence appetite and fat metabolism

Key points:

• Check for third-party purity testing (HPLC, mass-spec)
• Some peptides are research-only in certain regions — check local law
• Storage: many require refrigeration and light protection

Examples: some short peptides stimulate collagen and reduce visible aging signs.

• Topical vs systemic uses
• Combination with retinoids/peptides in skincare routines

Research is ongoing; some peptides show promise for neuroprotection and cognitive support.
