Peptides are small chains of amino acids that link together to form a basic building block of proteins and play crucial roles in many bodily processes, including signaling, immunity, and tissue repair.

Peptides are used to support skin health, promote collagen production, aid wound healing, and improve hair and nail strength. They are common in skincare, anti-aging serums, and haircare formulations.

Some peptides may influence muscle repair and recovery, but results vary and not all peptide products are proven or approved for performance enhancement. Always consult a healthcare professional before use.

Peptide safety depends on the specific peptide, dosage, and application. Some peptides are prescription medications or used in regulated medical therapies; others are sold as supplements with varying quality. Follow medical guidance and product labeling.

Look for products from reputable brands with transparent ingredient lists, third-party testing, clear potency information, and adherence to regulatory standards.
