I'd anihilate the lump with 2.5mg Femera - letrozole - while running Nolvaldex - tamoxifen citrate - at 20mg ED. Taper off the Femera - letrozole - and coninue the Nolvaldex - tamoxifen citrate - until all test is out of your system.
WARNING: Say goodbye to your dick if you run Femera - letrozole - at 2.5mg ED. It will crush that lump though for sure.
