Hello, friend! I suppose I'm not on your list of respected Androsterone testers, but for what it's worth I tested it. Twice, actually. With primary reference standards of known purity originating from 2 different laboratories. What other evidence would you like beyond the posted report?
I'm sure that the 'well respected' people you speak of are of the utmost caliber, with a superb track record of honesty and scientific integrity, and no competing interests to corrupt their opinions. They just can't find a good source they tell you, and I do empathize with their hardship, really.
Nevertheless, I'm generally not too interested in the objections and opinions of other chemists. It has been my overwhelming experience that their antagonism is rarely motivated by a sincere concern for the consumer (much less in defense of scientific truth) because in many cases I know who signs their checks! That's why I take the time to do my own testing, so we don't have to trust anybody else's opinion.
Also, NI sells Androsterone powder in neat form, so even a beginner level lab tech with some means of spectroscopy should have little trouble validating our good results for themselves. Then, if said individual (or courteous competitor) has behaved himself professionally, and been respectful toward NI on the public forums, they may approach NutraTeam for sourcing assistance and I suspect he'd be gracious enough to consider accommodations.
