What Are Peptides?
At their simplest, peptides are short chains of amino acids — the molecular building blocks associated with proteins throughout biology.
Peptides are short chains of amino acids, typically 2–50 amino acids in length, linked by peptide bonds. Amino acids themselves are the molecules that join together to form proteins. Depending on the length and structure of the chain, a molecule may be described as a peptide, a polypeptide, or a protein.

Peptides are found throughout biology. Because they can interact with receptors, signaling pathways, enzymes, hormones, and cellular processes, they have become a significant focus of laboratory and biological research worldwide.
Researchers study how specific peptides interact with biological systems — not to prescribe outcomes, but to understand the underlying mechanisms at work in living cells and tissues.

- Endocrine and hormonal research
- Cellular communication and signaling pathways
- Mitochondrial and energy metabolism research
- Tissue and repair pathway studies

What Does RUO Mean?
- RUO materials are for qualified laboratory research use only
- Not for human consumption, medical treatment, or diagnosis
- Not supplements, medicines, or approved drugs
- Not intended as dosing guidance or personal health advice
The abbreviation RUO stands for Research Use Only. FDA and eCFR labeling language for applicable research-grade materials uses the statement: "For Research Use Only. Not for use in diagnostic procedures."
CoreVials catalog materials carry this designation. They are not sold as medicines, supplements, or personal health products.
Research Compounds vs. Approved Medicines
Some peptide-based compounds have been studied in published clinical or preclinical research, and some may exist as FDA-approved medicines for specific regulated indications. These are not the same as RUO catalog materials.
- FDA-approved medicines have undergone regulatory review for safety, effectiveness, labeling, and quality.
- RUO catalog materials are not reviewed or approved for human medical use.
- Published research about a compound does not make a RUO catalog version of that compound an approved medicine.
CoreVials does not represent its catalog materials as alternatives to approved drugs or as products for personal health use.
