I really don't keep up with all the supplements coming and going. I have enough trouble with keeping up with all the meds. I have been in BB'ing for over 30 years. I tried everything on the market, and I was never satisfied with the promises. There are enough guys on the Boards who either sell or have used--they are the best sources for info, biased and unbiased. My biggest problem with supps is that they are neither classified as food nor drug. Therefore, supp cos are not required to put their supps through rigorous R&D like the drug companies do. I am certain there are some legitimate supps/herbs out there, for many of you use them and swear by them. So, do not discount them, just keep an eye out for results, research, and comments.
