What WordPress hook fires first admin_init or admin_menu

From what I’ve read on the internet the admin_init fires before admin_menu, is this true?

I have made a plugin template to test this and find it not to be the case.

The test code is below. The output I get when activating the plugin is …

2

ptsingelton Object
(
    [page] => pt
    [page_title] => Page Title
    [menu_title] => Menu Title
    [capability] => manage_options
)

Notice the number 2 in the output above, it’s output from the function admin_menu().
