Get a prescription for Nolvadex at 20-40mgs per day. Use that in combination with a bodyfat loss style regiment.
Also be sure that your estrogen is normalized after the run, or it will just return.
I have my clients use MuscleGELZ androshred along side of their Nolva Script. Now I do want to say I do rep for MuscleGELZ, but I also rep for many brands and I picked that item specifically because it works great in combination for safe and effective fat loss.
Also check your prolactin to be sure that that is in order, because although that is not the cause of gyno per say, that can effect the "appearance" of gyno. If you have elevated Prolactin levels, you often can see swollen nipples, and or lactating nipples, and this may make the "appearance" of gyno seem even worse.
Oh yeah, another method is freezing the area. This is not a well known method but you can do to a med spa and you can have them "freeze" areas with bodyfat. After the session, days later, the area will tend to bruise badly and then the area will shed fat deposits as you heal. This might sound impossible but I assure you it is not. This works well only on the fat deposits close to the skin. The large accumulations will either need the Nolva or Surgery to remove.
