Bro, if you have the start of gyno on a test only cycle, I would increase the adex and start nolvadex ASAP at 20mg ED, continued for a wk after the gyno has gone away. If you get gyno, you'll feel pain and sensitivity around the nipple and you will feel a small lump in the breast tissue around the nipple. This is a bad sign. If you follow these directions, it will get things under control fast.
If you are not getting pain or sensitivity and there is no lump, then there is a chance that it is just fat or water retention....aka man boobs. This happens to some guys more than others, when body fat or water retention is high.
