That's fine - but he claims he's got patents in the USA, etc - if this were a real product he'd have backers over there developing it.

Er, what? If you are talking about the person who first isolated Insulin, that would be E.L. Scott at the University of Chicago - between 1911 and 1912. The experiments were repeated by Israel Kleiner at Rockefeller University in 1919 (but his work was disrupted by WWI, so he never got to patent it).
Nicolae Paulescu, who is the person you're speaking of, (of the Romanian School of Medicine), did work in France, published it there, (in 1921) and patented it in Romania, but unfortunately Frederick Banting, working with Eli Lilly, produced the first pure insulin for sale before he managed to (1922)
Claiming that Paulescu discovered insulin is a bit rich!
