Arimidex or Letrozole??

[nightdemn]

I am going to start a cycle in about 4 weeks consisting of;
weeks 1-8----600mg's of test cypionate
weeks 1-4----40mg's of dbol per day
Now, i know that I am prone to gyno. Which do think would be more effective for blocking estrogen?? Arimidex or Letrozole??
Thanks!!!

Letro is the bomb. Works well and increases igf unlike ana which decreases it. Both work . Ive used letro w/ 1000 mg Test and 600mg EQ q week. No gyno No water blote
