You can check the recent papers (one Science and one JBC) on
the new insulin mimetic compounds, made by Merck, near your
emails address domain. I believe one of those papers (both???)
showed efficacy of the mimetic compound relative an inactive
analog. The inactive analog may be what you want. You could
compare to the active mimetic compound in your case.
