Deca is great for joint pain, but if they do ever decide to test for juice, then you might as well get ready to fail the test. It will be in you for a year and over. Same with Eq. You will have to weigh your options.
Also, at the doses you will be using, there is no real need to worry about sides. How much do you plan on taking here?
Winny may be of benefit, but I have heard from a few bro's that it hurts their joints after awhile. How true this is, I don't know for sure, but it is something to think about. If I were you, I would just use testosterone, unless you weigh out the options and decide that the deca life in the body is of no real harm.
This question also depends on your goals of size, strength, etc....
