Well, you probably know that methandrostenolone is structurally identicle to boldenone, with the exception of the C-17 methylation.
In that sense, equipoise could be called injectable D-bol.
That would be a misleading claim for the end user, though, because methylating a molecule significantly changes the way it behaves in the body. D-bol half life is short, as you know (<6hrs), and the gains are much more substantial than those from equipoise.
Anyone claiming to have an injectable steroid that will behave the same way D-bol does is most likely lying to you.
Now, if you are asking about an orally administered liquid D-bol, I would have to agree with those who have responed...just use the tabs.
