The body's own language.

The name carries a small piece of biology. The prefix endo- means endogenous — arising from within. We chose it because the molecules we work with are not foreign to the body. They are part of the language the body already speaks.

A peptide is a short chain of amino acids, typically between two and fifty residues. The same machinery that builds proteins builds them, and the body makes a great many — a family of signalling molecules that includes hormones, growth factors and neuropeptides. Together they help regulate processes as ordinary and as fundamental as metabolism, growth, repair, sleep and mood. They are, in the plainest sense, how cells talk to one another.

Each one is precise. A peptide binds a specific receptor on the surface of a target cell, and that binding sets a defined signal in motion — the cell does something it already knows how to do. The peptide does not impose a new instruction so much as deliver a familiar one. Sequences as short as three amino acids are synthesised and read by the body with this kind of exactness.

That is what drew us to this field. Most substances people consider introduce something external and ask the body to adapt to it. Peptides work the other way. They restore, direct and enhance what our biology already knows how to do — they prompt our own cells to produce, repair and regulate. The interest, for us, was never in adding what we do not have. It was in understanding what we already are, and the molecules that govern it.
