Been lurking for years, but we’ve finally gotten to a topic I understand (ie, dudes with tits).
The doctor is either ignorant on the subject or flat out lying. Yes, gyno can affect one side of the chest more then the other. Yes, it looks exactly like that and can come on rather quickly, as in weeks.
There are tons of examples of bodybuilders with one-sided gyno or more advance gyno on one side. I can’t believe that guy actually said that.
And yes, I know from experience. Don’t be surprised when that lump is gone next time you see him after having it surgically extracted.
