I would start taking a low dose of the letro immediately. Letro is very powerful. I would also start adding in an intense cardio routine. It seems intense cardio can also help eliminate gyno. Keep your diet clean, junk food will mess with your hormone levels. I would order some arimidex, and search here on EF on what dose of arimidex to use. Most do 1MG EOD. What are you running 250 of? 250MG of Test? Make sure you are doing cardio I promise that will help keep the gyno away. And get some ARIMIDEX instead of using that letro, that letro is for extreme cases and if yours is just starting you want something milder. But you can start using the letro at a low dose until you can get some arimidex. Keep that diet clean also. Diet can help cause gyno aswell.
