Hi, i posted this yesterday but can't find it now so maybe i did it wrong. sorry. i have a brown glass bottle with a green cap from century pharmaceutical group. the person i received this from said it used to be uspharmaceutical but the name has changed. it's a white label with a thick blue stripe on the bottom and a thin red stripe above the blue. Inside the blue is wear it says century pharmaceutical group in white.
