Peptides have gained significant attention in the health and wellness industry due to their potential benefits. However, there is often confusion regarding whether peptides are classified as drugs, supplements, or serums. In this article, we will explore the nature of peptides and clarify their categorization.

What are Peptides?

Peptides are short chains of amino acids, the building blocks of proteins. They are naturally occurring in the body and play crucial roles in various physiological processes. Peptides can be found in food sources, such as meat and dairy products, and can also be synthesized in laboratories for medical and research purposes.

Peptides as Drugs

Peptides can be classified as drugs when they are specifically formulated and approved for therapeutic use. These pharmaceutical peptides are designed to target specific biological pathways and have a direct impact on the body’s functions. Examples of peptide drugs include insulin, which is used to manage diabetes, and certain cancer treatments.

It is important to note that not all peptides are classified as drugs. Many naturally occurring peptides in the body serve regulatory functions and are not considered pharmaceutical drugs.

Peptides as Supplements

Peptides are also available as dietary supplements. These supplements contain specific peptide sequences that are believed to have various health benefits. They are typically marketed as performance enhancers, anti-aging solutions, or muscle-building aids.

Peptide supplements are not intended to treat or cure any medical conditions. Instead, they are marketed as a means to support overall health and well-being. The efficacy of peptide supplements is still a subject of ongoing research, and individual results may vary.

Peptides in Skincare: Serums

Another popular application of peptides is in skincare products, particularly serums. Peptide serums are formulated to target specific skin concerns, such as wrinkles, fine lines, and loss of elasticity.

When applied topically, peptides in serums can stimulate collagen production, which helps improve the skin’s texture and reduce the signs of aging. They work by signaling the body to produce more collagen, a protein that provides structure and support to the skin.

It is important to note that while peptide serums can be beneficial for skincare, they are not considered pharmaceutical drugs and should not be used as a substitute for medical treatments or prescriptions.


Peptides can be classified as drugs, supplements, or serums, depending on their intended use and formulation. Pharmaceutical peptides are specifically designed for therapeutic purposes and require approval from regulatory authorities. Peptide supplements are marketed as dietary supplements and are not intended to treat or cure medical conditions. Peptide serums, on the other hand, are skincare products formulated to target specific skin concerns.

When considering the use of peptides, it is important to consult with healthcare professionals or skincare experts to determine the most appropriate and safe approach for your specific needs.
