Well, most of the guys here think the dbol bridge is a myth. The one guy I know of who actually did the bridge and got tested had test levels of a little 8 year old girl.
I really don't see the need to do any kind of post cycle therapy (pct) if you are going to do the dbol bridge since that should be enough to keep muscle on.
Oh, and I'm one of the guys who thinks it's a myth. The fact that some jackass put the breakdown of dbol as a mathematical formula has zero bearing on reality. Hell, isn't oxandrolone a billion times more powerful on paper than test?
