I'm running 450 mg of deca/week, 250 of test and 5 IU's of HGH/day and no signs of deca dick (I'm actually a bit out of control in the other direction). Really the only side effect I've noticed is that deca at that dose gives me a looooong time to "fire" -- basically unless you specifically think about coming and focus on it, you aren't gonna go.
I am taking anti-e's (0.5 mg of Arimdex EoD), but didn't start Dosinex @ 0.5 mg 2x per week until my 8th week of a 10 weeker. I'll probably take the Dosinex through PCT as well, just to play it safe.
I've heard bad things about Bromo and people rave about Dostinex.
