Peptide glossary.
A scientific reference to every compound we supply — what it is, the pathway it acts on, and why it's studied.
Short chains, specific signals.
Peptides are short chains of amino acids linked by peptide bonds — smaller and simpler than full proteins, but often just as functionally precise. Many occur naturally in the body as hormones, growth factors, or signalling molecules, triggering a specific response when they bind to a matching receptor on a cell's surface.
The entries below explain the mechanism of action behind each compound we supply: which receptor or pathway it engages, how its structure differs from related compounds, and why it appears in the research literature. This page is a scientific reference only — it does not describe dosing, administration, or any human or animal use. Every compound on this site is sold strictly for in-vitro laboratory research.
