I'm a member of the DNA Fan Club!
I turn quite a bit of green wood and have found the DNA to work extremely well. I usually turn the piece to 1 to 3/4 inch thickness, then soak the project in DNA for two days. Next I air dry the piece until the DNA has evaporated (an hour or so), then wrap the project in several sheets of newspaper and set it aside. After two or three months (as opposed to 6 or 8 without DNA) the piece is ready to remount and turn to completion.
DNA will speed up the drying process, and I've found it will also greatly help in reducing checking. It will not keep the bowl from warping, that's why a 3/4 to 1 inch rough thickness and a final turning.
