Research

Peptides and proteins are both made from amino acids.

Peptides are generally shorter chains, while proteins are usually larger and more structurally complex. The exact distinction can vary depending on the scientific context.

Peptide science has developed over more than a century.

Early research into naturally occurring peptide hormones helped scientists better understand amino-acid chains and their role in biological systems. The discovery and development of insulin in the early twentieth century became one of the best-known milestones in peptide-based medicine.

Since then, advances in chemistry and biotechnology have made it possible to identify, synthesize, analyze, and study a wide range of peptide molecules.

Today, peptide research is conducted across fields including:

• Molecular biology
• Analytical chemistry
• Biotechnology
• Diagnostic development
• Pharmaceutical research
• Protein and receptor research

Some specific peptide-based drug products have received FDA approval for particular uses. That approval applies only to the specific finished drug product, formulation, manufacturer, labeling, and approved indication. It does not extend to other products containing the same or similar ingredients.

Researchers study peptides to understand their chemical structure, physical properties, purity, stability, and interactions with other molecules.

Laboratory analysis may examine:

• Amino-acid sequence
• Molecular weight
• Purity
• Identity
• Solubility
• Stability
• Degradation
• Behavior under controlled experimental conditions

Findings associated with one peptide should not be applied to another peptide or interpreted as instructions for human or veterinary use.

Many peptides occur naturally in living organisms.

Synthetic peptides are produced using controlled chemical or biological processes. Researchers may synthesize peptides to:

• Study a known amino-acid sequence
• Compare molecular structures
• Conduct analytical testing
• Develop laboratory methods
• Investigate stability and degradation
• Support biotechnology or pharmaceutical research

Synthetic production does not automatically establish that a peptide is approved, safe, effective, sterile, or suitable for human use.

A research-use product is a material offered for legitimate laboratory investigation.

Research-use materials are not automatically medicines, compounded drugs, dietary supplements, cosmetics, or FDA-approved products. A research-use designation does not authorize administration to humans or animals.

NorCal Peptides research materials are offered exclusively for laboratory use and are not intended to diagnose, treat, cure, mitigate, or prevent disease.

A Certificate of Analysis, commonly called a COA, reports selected testing information for a particular batch or lot.

A COA may include:

• Product or material name
• Batch or lot number
• Reported purity
• Identity testing
• Test method
• Test date
• Laboratory information
• Storage information

A COA reports only the tests performed and the results shown in the document.

A COA does not, by itself, establish:

• FDA approval
• Clinical effectiveness
• Suitability for human or veterinary use
• Sterility
• Absence of every possible contaminant
• Compliance with every pharmaceutical manufacturing standard
