There are users for whom use of nandrolone (e.g. Deca Durabolin) makes sense. If someone knows from experience that this steroid helps his joints during a cycle while not using it leaves him with these problems, then that is a good reason to use it.
Or if he has joint problems and wants to see if Muscle powder Deca Nandrolone Decanoate would help, that can be a good reason. It can be worth a try to see if there is a benefit.
From the standpoint of serious bodybuilding I think aid for the joints is the only good reason to use it in favor of other oral anabolic steroid.
There can also be a cosmetic casual-user reason where only a very low dose of steroids is going to be used anyway and there is great fear for the hair.
Where these are not issues, Deca interferes with post-cycle recovery of natural testosterone moreso than is the case with other injectables. For many it also can cause depression and/or libido problems.
So if the above particular reasons to use Deca don’t apply, then there are better choices.
