I have no idea what is wrong with some people here. I guess theyre illiterate. The link I provided is a very thorough study...READ IT!!! I even provided my own personal experience. All for nought I guess. I'm not sure exactly what responses these people are looking for, but I guess clinical studies and anecdotal experiences are what they are not looking for.
Here is some info. from that link in regards to Clomid, and Nolvadex:
Clomiphene, an antiestrogen, can be administered on a trial basis at a dose of 50-100 mg PO every day for up to 6 months. About 50% of patients achieve partial improvement in breast size, and about 20% of patients might note complete resolution. Figures vary with the type and duration of gynecomastia. Side effects are rare and include visual problems, skin rash, and nausea.
Tamoxifen, an estrogen antagonist, is effective for recent onset and tender gynecomastia when used in doses of 10-20 mg PO twice daily. Up to 80% of patients note partial-to-complete resolution of gynecomastia within 3 months. Nausea and epigastric discomfort are the main side effects.
