I read their "White Paper" on prostate issues. They market that along with the bulletins. (I did not buy the bulletins). The White Paper is good, although as someone who has done a fair amount of reading about prostate cancer, there was very little there that I did not already know. But for someone who is just starting to learn, I think it was a good basic publication, and a quick read.
