Pansy-mae: The references you've found almost certainly relate to advice to guys who have sudden and unexplained and unwanted gynecomastia...however, we WANT it and know why it is developing and are actively promoting it, so no need to worry about that, as such ( unless you are worried by what is happening in which case you shouldn't be doing this in the first place).

Yes this is true. I was just worried because nothing happened for so long with NBE, and then in Feb, the mass was there all hard and sensitive, so I wanted to know if it was normal development, hence the research.
