The stories about deca gyno are overblown. In nearly all of those cases, it's the fact that they're taking high doses of test which is causing their gyno. Usually those guys are taking doses of test that are higher than their dose of deca (usually, because they need the test to aromatize in to DHT which is the proviron's purpose). the side effect is that the test causes higher estrogen levels too and high estrogen is known to also signal prolactin production.
Here's a good read on that matter:

But anyways you can do whatever you want. I really don't care if you take my advice or not. I really don't see the point in asking advice though, if you're just going to dismiss it when they give it to you. Did you really just want a bunch of strangers giving you a "thumbs up?"
