I've had the same thing on higher doses of tren. No noticable gyno (meaning a lump), but nips can get puffy and have had a clear liquid ooze out. Actually had a chick notice it once... she woke me up to ask me what it was. Haha I can laugh about that now, but I was embarassed at the time. Anyway, 10 mg of nolva a day seems to take care of it.
