About Peptides

How peptides actually work.

Peptides are short chains of amino acids linked in precise sequences. The body uses them everywhere: as hormones, neurotransmitters, growth factors, and immune messengers.

Because peptides are built from materials the body already recognizes, they tend to be remarkably selective without scattering effects across unrelated systems.
