Suggested treatment options
Here is what emedicine.com suggested for treatment.
Clomiphene, an antiestrogen, can be administered on a trial basis at a dose of 50-100 mg/d orally for up to 6 months. Approximately 50% of patients achieve partial reduction in breast size, and approximately 20% of patients note complete resolution. Outcomes vary with the type and duration of gynecomastia. Adverse effects are rare and include visual problems, rash, and nausea.
Tamoxifen, an estrogen antagonist, is effective for recent-onset and tender gynecomastia when used in doses of 10-20 mg orally twice daily. Up to 80% of patients report partial-to-complete resolution of gynecomastia within 3 months. Nausea and epigastric discomfort are the main adverse effects.
Personally I would put the Nolva at about 60mg per day until I started to notice some improvement. Then I would back down to 20-30mg until I felt that it was not goining to work any further. If I was really concerned about gyno I would also stop my cycle early and begin a clomid + nolva regiment.
Hope this helps
