The only way to get rid of gyno completely, is to have it cut out. If you go this route, you may also need lypo to conture your pec so the shape looks right. Doctors that specialize in gyno removal will do both in one shot. If your gyno isn't bad, you may be able to get the lump to reduce in size by using an AI. I would suggest you go for the big guns and use letro. If you have tender nipples, 2.5mg ED for several days after the pain has gone away and then continue on 2.5 EOD to see how small you can get the gland to shrik. Eventually though, this is going to dry you out and you'll have to back the dose down. You don't want your estrogen to be too low for too long
In the future, while cycling, you'll want to be very careful with what you use. You need to be sure to not let estrogen get too high. So some drugs like dbol may be more likely to cause an issue. Always use an AI on cycle
