What Is A Peptide?

Peptides are short chains of 2 to 50 amino acids linked by chemical bonds, serving as the building blocks for proteins and playing vital roles in fundamental biological processes such as hormone production, cell signalling, and immune function. They act as messengers in the body, regulating everything from appetite and blood sugar to skin elasticity, wound healing & muscle growth.

Peptides are most commonly administered via injection, either subcutaneously (under the skin) or intramuscular (into a muscle) for maximum absorption.

Other, less common methods include nasal spray, topical creams, and oral supplements, though oral peptides often have limited absorption due to digestion. The best method depends on the specific peptide and its intended use.
