Confusion exists due to many different problems being called the same thing and the condition having many different causes.
Puffy Nips is a very vague term meaning many different things to different people. Standardized pictures are a better way to describe the problem. Contour distortions of the nipple areola can be from fat, gland, and or skin.
There are many possible causes for gyno, gyne, puffy nips, and puffed nipples (all common terms for gynecomastia).
Treatment options depend on the actual defomity and cause. Evaluating what works would require better defining what is wrong, the cause, and what actually was done for treatment.
I thought I had gyno after my dbol only cycle. It got pretty bad and I got scared and did a "Nolva blast" as I called it. I did 100mg for a week, 80 for a week and 60 for a week. Did nothing for me. Now, 2 months later, they went away on their own. Slowly but surely, they shrank and I just barely have slight puff left(which I have proviron on the way to try to get rid of the last little bit).
