'Highly unlikely gyno could start after 5 day'...are you sure? You are wrong I'm afraid, although you may not develop full tits after 5 days, the breast pain may well be an indicator of early gyno. It takes a while for breast tissue to be visible, but not long for it to start to develop.
As for 'like i said, guys who are starting to lose, are probably at the age were they start to get fat too, and blame it on the drug', well I had/have body fat of 19% and in great shape and I got gyno. You are talking nonsense and some of you fellas who doubt this obviously feel that just because you havent experienced it yourself, it doesnt exist. Well it does and just be thankful that you didnt get it.
Soy milk is no good for gyno...tamoxifen is about the only thing that will make any difference, but like I said earlier gyno is not reversible for a percentage of unlucky sufferers.
