Thanks guys. Just one other thing to help my understanding of how these supps are brought to market. Am I right in thinking that closed testing will already have taken place before it's made available for public beta testing in forums? If so, what blood tests are carried out on the first testers? E.g. do you check that a new supplement has no adverse effect on liver values or lipids, and that all hormones return to normal levels after stopping taking the supplement?
As you can tell, I'm quite cautious with these things, I've used JW and thought it was effective, but I do worry about what exactly I'm putting in my body
