Research peptides are those synthesized for study in the lab that can lead to new breakthroughs and future pharmaceuticals, but they become medicines only after undergoing rigorous study, clinical trial, and, crucially, the FDA approval process.

What is a Peptide?
A peptide is a biologically occurring chemical compound containing two or more amino acids connected to one another by peptide bonds. A peptide bond is a covalent bond that is formed between two amino acids when a carboxyl group or C-terminus of one amino acid reacts with the amino group or N-terminus of another amino acid in a condensation reaction (a molecule of water is released during the reaction). The resulting bond is a CO-NH bond and forms a peptide, or amide molecule. Likewise, peptide bonds are amide bonds.
What are Research Peptides?
Simply, research peptides are any peptides that are used in scientific research. In recent years, peptides have gained recognition as being highly selective and effective in therapeutic applications, all while being relatively safe and well tolerated in subjects and patients. As a result, there has been a huge uptick in interest in peptides for pharmaceutical research and development. With the promising potential that peptides present for medical applications, more and more research, study, and experimentation with peptides is necessitated in order to unlock the pharmaceuticals and therapeutics of today and tomorrow. Consequently, there has been a surge of demand for research peptides to fuel progress in these new avenues of research.
How Are Peptides Formed?
Peptides are formed both naturally within the body and synthetically in the laboratory. The body manufactures some peptides organically, such as ribosomal and non-ribosomal peptides. In the laboratory, modern peptide synthesis processes can create a virtually boundless number of peptides using peptide synthesis techniques like liquid phase peptide synthesis or solid phase peptide synthesis. While liquid phase peptide synthesis has some advantages, solid phase peptide synthesis is the standard peptide synthesis process used today. Read more about peptide synthesis.
Research Peptides vs Medicines?
Importantly, research peptides are only made available for in-vitro study and experimentation. From the Latin for “in glass,” in-vitro refers to studies performed outside of the body. Hundreds of peptide therapeutics have been evaluated in clinical trials, and scientists and researchers around the globe are using research peptides in the lab to explore beyond the realm of traditional peptide design, pushing the boundaries to discover peptide variants that can be used as pharmaceuticals in the future. Already, there are over 60 peptide-based medicines on the market that have received approval from the US Food and Drug Administration (FDA). Among these are LupronTM, a treatment for prostate cancer, and VictozaTM, a treatment for type 2 diabetes. Both pharmaceuticals have achieved sales in the billions. However, it is essential to recognize that such FDA-approved drugs are NOT research peptides, they are just that: FDA-approved medications able to be prescribed by a healthcare professional for the treatment of a specific condition.
