is it wrong to write insulins as a plural?
I am not a professional teacher, but a lot of my tuition work is with a diabetes nurse and I would say that it is not necessarily wrong, but it would be unusual. The only circumstance in which the word would be pluralised that occurs to me would be if talking about insulins from different sources. For example, one could say "there two different insulins in use today." I don't think that one would, but one could. Even then, the plural looks very odd, but is grammatically correct.
