Research Peptide Glossary

Sterile water with 0.9% benzyl alcohol as a preservative. It is the preferred solvent for reconstituting peptides because it allows extended storage.

The recommended storage conditions for reconstituted peptides (2–8°C). Lyophilized peptides are stable at room temperature.

Organic molecules that are the building blocks of proteins and peptides. There are 20 standard amino acids in the genetic code.

Body Protection Compound-157. A 15-amino-acid peptide derived from a gastric protective protein. Studied for its regenerative properties in tissues.

Certificate of Analysis. A document that verifies the identity, purity and quality of a peptide through independent laboratory testing.

The process by which a peptide loses its structure and activity. It can be caused by heat, light, moisture or oxidation.

An analytical technique that measures the molecular mass of a peptide to confirm its identity. It complements HPLC analysis.

An incretin hormone that works synergistically with GLP-1. Retatrutide activates GIP, GLP-1 and Glucagon receptors simultaneously.

An incretin hormone produced in the gut that stimulates insulin secretion and reduces appetite. Tirzepatide and Retatrutide are agonists that include GLP-1 receptor activation.

A classification indicating a high-purity peptide with verifiable certificates of analysis, suitable for professional use.

High-Performance Liquid Chromatography. An analytical technique used to verify peptide purity. A purity of ≥99% indicates a high-quality product.

A freeze-drying dehydration process that preserves peptide stability. Lyophilized peptides have a longer shelf life and are easier to store.

A unit of mass equal to one millionth of a gram. Peptides are commonly dosed in micrograms.

A unit of mass equal to one thousandth of a gram. Used to express the total amount of peptide in a vial.

Nicotinamide Adenine Dinucleotide. A coenzyme present in all living cells, crucial for energy metabolism and DNA repair.

A short chain of amino acids joined by peptide bonds. They generally contain between 2 and 50 amino acids and are important signaling molecules in the human body.

The process of dissolving a lyophilized peptide in an appropriate solvent (usually bacteriostatic water) for use.

A triple agonist of the GIP, GLP-1 and Glucagon receptors. It represents the latest generation of metabolic peptides, with superior results in Phase 3 studies.

A 43-amino-acid peptide naturally present in the body. Researched for its role in cell regeneration and tissue repair.

A unit of measurement based on the biological activity of a substance rather than its mass. Common in peptides such as HGH.

The time it takes for the concentration of a compound in a biological system to fall by half. A key pharmacokinetic parameter in research.
