I wish I could help you with your question as I too have been very interested in Fareston. Not one post seems to have the answer but several posts telling you not to use Letro. Really? Even after you have a lump?

I am by no means an expert but by the time you have a lump, Nolva for me is no longer an option. I have never read an article or a post about someone ridding a gyno lump with Nolva. Maybe puffiness but not a lump.

Letro: Harsh? Absolutely. Necessary for gyno lumps? Absolutely.
