9A 'Polypeptides produced by the pituitary gland' I have "E?D?R?H?N?" = 'Edorphons'? Googling this last word gets 'funny' sites while googling key words of question gets learned medical sites but no words that fit.
Thank you`folks. I had this word in the back of my mind that I thought i'd heard before ( I hadn't!!) and I was fairly close... Site seems to be OK tonight.
