Exemestane, anastrazole, letrozole. Nolvadex and Clomid. Those are the best RC Chems to treat gyno. Letrozole is by far the strongest but is very hard on the body. If the gyno is minor you might not need Letrozole. I am no expert as I haven't had gyno yet. Others will chime in I'm sure. If I were you I would order Nolva, exemestane, and Letrozole just in case ASAP. Always good things to have on hand if you cycle.
