The Fastest-Growing Peptide Research Community

Peptides are short chains of amino acids (typically 2–50) linked by peptide bonds. They're smaller than proteins and serve as signaling molecules in the body. Your body naturally produces thousands of peptides that regulate hormones, immune function, digestion, and cellular repair. Scientists study synthetic peptides to understand how these biological systems work.

Not exactly. Both are made of amino acids, but proteins are typically 50+ amino acids and fold into complex 3D structures to perform functions. Peptides are shorter chains that primarily act as messengers — they signal cells to perform specific actions. Think of peptides as text messages and proteins as the employees who carry out the work.

Peptide research is at the forefront of modern medicine. Over 80 peptide drugs have been approved by the FDA, including insulin (the first peptide therapeutic). Current research is exploring peptides for metabolic disorders, neurodegenerative diseases, antimicrobial resistance, and cancer immunotherapy. Understanding peptides helps us understand the fundamental language cells use to communicate.

HPLC stands for High-Performance Liquid Chromatography. It's the gold standard for peptide purity analysis. The process separates a peptide sample into its components and measures the relative abundance of each. A result of "≥99% purity" means at least 99% of the sample is the intended peptide, with less than 1% impurities or degradation products.

GLP-1 (Glucagon-Like Peptide-1) is a hormone your gut produces after eating. It signals the pancreas to release insulin and tells the brain you're full. A GLP-1 receptor agonist is a synthetic peptide designed to mimic this signal. Examples like semaglutide and tirzepatide are among the most studied peptide drugs in history, with multiple FDA-approved applications.
