wouldn't it defeat the purpose if you had to use the whole pill? i mean becasue even if you did buy two at the same time, that looked the same, from the same person it doesn't mean it would have the exact same things or even any of the same things....and why would you want to send it in for that same reason? cuz i don't think they send back your ex.....and is there some protection against them just turning over your name to the govt???
