It is not possible to have a 1 ene and a 2-oxa. It also says dione while at the same time saying 17b-hydroxy and 17a-methyl -- can't have them all.
It is also impossible to have a 4 ene and a 5-alpha.
Appartently this is the impossible molecule.
This is the second product I have seen from this company that shows that they are either intentionally making errors in their nomenclature or they have no clue what they are talking about -- sounds like something I want to buy.
