(5a-androstanol[2,3]furazan-17b-tetrahydropyranol) is furazan. Only furaza product I know of is Katanadrol2.0 and it's already sold out.
Also 2a,17a-dimethyl-5a-androst-3-one-17b-ol (Superdrol) which is still in stock in quite a few places.
If I'm not mistaken the ban is effective as of 8-28-12. After that no company can make these compounds, however if there are any still in stock, they will be able to sell the remainder.
