Yes this is a good topic. I've thought about the same thing myself.
Number one, it's my opinion that any success that one has with urine lures is NOT from the urine itself (which is no longer urine anyway by the time you get it, but in fact urea) but from the phermones that are in it.
Goose made a real good point in another thread about the urine not getting any of that particular animal's hormones until AFTER it had passed through the sex organs. This makes perfect dense, because urine that is in the bladder is sterile.
So.....if we can reason that the "active ingredient" that makes urine a good lure are the HORMONES/PHERMONES, then one would also conclude that if those hormones/phermones can be isolated or made synthetically, then we don't really need that smelly, nasty sour urine in the first place, as it's only a carrier.
Makes sense to me.
As I and others have stated before, we've had just as much success using our OWN urine is scrapes, as the commercial stuff. The only reason I can come up with for this, is that even if a deer can tell that my urine is not a deer's it doesn't care, because my male hormones are the same, and my hormones are those of an "outsider", hence the scrape being hit. If I were a woman, then my results may even have been even more dramatic. I also believe that if you could collect urine from female domestic animals that were in estrous, that the results would be every bit as good, if not better, than from commercial bottled urines.
This is by no means a scientfic statement, just a "what else can it be" type conclusion. I've had it work often enough that it ISN'T a fluke.
