I would imagine the test-c is 1cc every 12 days (not 1mg every 12 days), with each 1cc being 200mg.
IMO, you will probably see some(?) strength and weight gains with the addition of the Dbol.
I also don't think the Milk Thistle will hurt you, but won't do you any good either...........again, JMHO.

If you continue to inject the test-c after the 8 weeks of Dbol, how will you be post-cycle? Or, when you stop the Dbol after 8 weeks, will you no longer inject the Test-c?
Just offering my thoughts after reading your post.
