I don't agree with that. I'm from the old school. Dbol these days gets sold as 5 or 10mg tabs. Back in the day, we had some pharma grade stuff, they were all 50mg a pill.
I've tried Dbol at 30, nothing but water and lousy gains. But with 50mg, I blew up and retained solid gains.
6-8 weeks is a long time for Dbol and I would worry about the liver, and BP as you said.
Thats just my experience with Dbol, works great at a high dose for a short time.
And please use Nolva with it, very high risk for gyno.
