"Nonum" is latin, and I've never seen that even once in chemistry... it doesn't fit IPUAC nomenclature, so I'm guessing it's made up.
Dianabol has many names, but it's really just -methytestosterone with an extra C=C bond next to the =O.
If someone can't even use one of the dozens of recognized names already in use, I'd advise a bit of caution, just to be safe.
