Over the last 10 yrs I personally know of 2 women who have used deca. One loved it and used it regularly, one tried it and blew up, hated it, dropped it.
Generally NPP is going to be recommended for women who are interested in running something along the lines of deca - an example is for the joint protection aspect, or if they are interested in doing a more aggressive cycle. I wouldn't bother recommending anything like even NPP to anyone unless they are really serious about putting on some size. And I'm not talkign like "figure competitor" size. Similar to running some test prop - expect all the androgenic sides and a long time for it to clear. Deca is a very long acting compound and takes very long to clear if you don't like the sides. Also women don't generally like the moonface that comes w/ the amount of water retention that deca promotes.
Unless you're really interested in getting pro FBB-level jacked, I don't see any reason for women to use deca, if you don't already have a LOT of experience and know what you're doing. If you are a guy asking for a girl, because she wants to try something and you happened to have some - fucking don't do it. This is NOT something someone else should "put" someone else on. This is something THAT PERSON needs to understand and own if they are going to decide to do a deca cycle.
