   Athena Peptides Education — home page wayfinding

   The band directly under the hero: a peptide search box, a link to the full
   A–Z, and four routes into the rest of the site. It exists so a visitor who
   already knows they want BPC-157 can be on the BPC-157 page in one action,
   without reading an educational section or opening a menu first. Everything
   below it on the page is unchanged.
