If by DC you mean Dogcrapp, I'm using it now. I've been doing it around 4-6wks. So far I really like it. Strength is up in everything (I also started a cycle at the same time though). The workout seems to allow you to focus on your good heavy lifts, and cuts out all the lessor stuff. One thing, I don't know if it is good or bad, but, I don't get as sore as I used to.
