the nandrolone base is known as steranabol, check big cat's steroid profiles
the test base 4OH is similar to the aromatase blocker 4hydroxyandrostenedione sold as formasin by prototype and aromazap by syntrax. only difference is alcohol on C17 instead of ketone.
as for the 4OH its not hard, just dangerous, damn osmium tetroxide. its kind of nasty. although i think i came across a reaction that was different, maybe it is possible to do at home.
cheers, pete
