What a peptide is
Peptides are short chains of amino acids — typically 2 to 50 residues — joined by amide bonds. They are smaller than proteins and usually act as signalling molecules rather than structural or catalytic ones.
Science
Peptides are signalling molecules — precise, fragile, and unevenly studied.
This page explains the fundamentals without marketing language, so that the compound dossiers can be read critically.
How they signal
Most act at receptors or modulate local signalling cascades: receptor binding changes intracellular second messengers, gene expression or cell migration. Effects are pathway-specific, dose-dependent and often local.
Stability and handling
Peptides are sensitive to temperature, pH, repeated freeze-thaw cycles and light. Research handling relies on cold-chain storage, correct reconstitution solvents and documented stability windows.
Why evidence varies so much
Some compounds have decades of controlled trial data; others exist only in rodent injury models. Mechanistic plausibility is not evidence of human benefit, and we do not present it as such.
