Talk:Histidine-tryptophan-ketoglutarate

I've attempted to expand the references section of this article as well as provide an external link to a webpage which contains relevant information regarding distribution of HTK. My changes have been deleted by overzealous editors. They are relevant, informational and not promotional- they should be made available to all Wikipedia users. — Preceding unsigned comment added by 212wikiupdate770 (talk • contribs) 19:49, 2 March 2012 (UTC)
