You’re talking about the search path formed by ‘guix environment’,
right?

~/.guix-profile/etc/profile prepends things to the search paths, but
it’s up to the user whether to source it before or after other
definitions have been provided (in .bash_profile or similar).

On GuixSD, for instance, my GUILE_LOAD_PATH has:

  ~/.local and similar entries
  then ~/.guix-profile/share/guile/site/2.0
  then /run/current-system/profile/share/guile/site/2.0
