There are different kinds of gyno, mine is mostly pre-pubertal fat. I used to be pretty fat in those days.
But now, no matter how much cardio I do, I can't get rid of the fat on my chest. I once dieted down to 76 kg and still had it.
I've read enough about gyno and used Ralox, Rebound, Nolva, .. nothing helped.
So now I'm looking at this option.. I'm going to inject myself so that was why I asked for dosage guidelines or experiences. It is an injectable form of lecitine called phosphatidylcholine.
