I am currently running the following for the past month. Sust - 275Mg M,W,F Tren - 100Mg M,W,F and Win - 50Mg ed. After one week I noticed Gyno coming on so I ordered Letro from from a reputable source. It took about a week to get the letro and by the time I started the letro I had a hard lump under my left nipple about the size of a quarter. I have been running the letro for a little over two weeks now and if anything the lump is slightly larger. Also, my nipples hurt like hell. Am I not giving the letro enough time to start working? Has anyone else here had a similar experience? Any suggestions.
