1. arimidex is a vey poor choice, especially if you got gyno from 30mgs of prop EOD.
2. DO NOT USE NOLVA WITH DECA (this can WORSEN symptoms- via upregulation of the PgR)
3. use an AI. Reccomend AIFM or aromasin, you can also use letro (though at your dosages you may find it way to too strong).
4. Would clear up your gyno FIRST, before adding the nandrolone (also reccomend using NPP so that if there are issue you can cease use rapidly)
