Weekend cart was the annoying bit. Added semax, closed the tab, came back and wasnt sure what id actually picked so i went through it again. Once it shipped the box was fine. Label matched. Vial intact. Nothing missing. Not a perfect order because of me, but the box itself was right. Would order again now that i know the site.
