The key word here is 'probably' not. I am a retired health professional.  It is well known in the biz  what to trust generic and what not to trust. I would never take or recommend generic thyroid or  antibiotics. They are both known to be 'iffy' in their reliability. Given the recent melamine fiasco in China, just how much trust are you willing to put in an overtaxed understaffed system to make sure your overseas meds are 'safe'?
