Let me ask you two something while I have your attention here.
Eph can cause problems with erctions and some other things, due to its vaso-constrictive properties (it shrinks blood vessels).
Does NorEph do the same?
My understanding is that it does, thats its similar to Eph with respect to this effect, but I was wondering if you guys had any real data either way, good or bad (its has the same effect or maybe it does not) either based upon pharmacology and study, or anectodally.
