Bro, that is some inspring progress! 100% improvement and change. It is amazing what a sound diet can do.

As far as Gyno, its hard to tell but it looks like chest fat to me. If you continue to lean out a bit more and add some muscle to your frame, that chest fat should dissapear.

Keep doing what you are doing, I would not say its quite time to start bulking yet but you can alter your diet so that you can add some LBM without adding any more bodyfat.

Keep up the great work and keep us posted on your results.
