What Are Peptides and How Do They Work?

Peptides are short chains of amino acids – the same building blocks that make up proteins. Think of them as tiny messengers in your body that tell cells what to do. Because of their small size, peptides can easily interact with receptors on cell surfaces, triggering specific biological responses.

Your body naturally produces peptides for many essential functions, such as healing, hormone regulation, energy production, and maintaining healthy skin. Scientists have also created synthetic peptides to mimic or enhance these natural processes.

Different peptides have different roles. Some support muscle repair and recovery, others promote fat loss, boost collagen for healthier skin, or improve cognitive function. Because they work at a cellular level, peptides are highly targeted—making them a powerful tool in both medical research and wellness applications.

In short: peptides act like signals that help the body repair, regenerate, and optimize its natural functions.
