SERMs for stopping gyno issues, if you were to have estrogen get out of control, Nolvadex. But if you manage estrogen to begin with, using an AI like Arimidex, you can avoid running into problems. Issue is, these things are highly over used now days. You don't want to destroy estrogen.As you saw back in the day, you could do a lot without a ton of estrogen control. Too much control and you run into issues too. The best way to see if you are in range is to run your cycle for a month with Adex and then get labs to check. So if you use about 500mg test a week, somewhere around .5mg 3x wk should be a good dose to start with. As long as you have your Ai controlling estrogen, there will be no need for a SERM like Nolvadex on cycle. Then post cycle, you can use Clomid for PCT. Thats the basis strategy guys are using now days
