anabolics2000 book talks about using the two together when using let's say testosterone. the propecia will help to stop the conversion of test into dht and the arimidex will help stop the aromatization of test into estrogen so u can get the most out of your test without all the side effects. sounds good on paper huh. im sure in the real world this would work well too. dunno though never tried the combo of all 3
Propecia reduces DHT, and DHT is good. I might take it on a cycle of test but otherwise the shit is going to make your sex drive go downhill. Shit, it may even hurt your gains a little. Maybe try some topical sprironolactone, and Xandrox.
