If any of you bros use a Nandralone or Tren, please use either of the two to block progesterone based gyno. If didn't and I got lumps in both my pecs, that quite honestly scared me. I got it checked out by a doctor, and I'm fine, but the worry wasn't fun. I know one of the two (Dostinex or Cabaser) causes side effects. I don't remember which one. Mr. X mentioned it in a thread.
