That is what real urine does. Still needs to smell like coyote or cat not sewer. Ammonia dissipates quickly. If there is a salts build up in the bottom after aging you got real urine and good stuff. If no salts after ageing, probably man made crap.

The fake stuff will smell like ammonia because they know the trapper is expecting that and it's easy to do. The pee I collected will get a slight ammonia smell but it doesn't overpower the coyote smell, not close.

No doubt this was bad as the ammonia smell was very strong. Understandably was disappointed as I understood he had a good product.

There Is a supplier In Indiana that probably supplies urine to all these other mentioned names. I have heard nothing but good things about his product. And It's not Dr. Bob. I'm not sure Dr. Bob Is even In the urine market anymore.

All aged bottled urine will develop some ammonia odor. That is a natural byproduct of contained urine as it sits for a while. No escaping that. Human urine will react the same way.

Ever visit an old age home and you will understand what I mean once you encounter that situation. Ammonia is very lingering and quite obvious in those institutions that aren't well maintained. Some of that odor is likely from some occupants that are wearing soiled under garments as well.

Some older Coyote and Cat urine can really take your breath away and burn your nostriles out of a freshly opened jug if you get a good enough wiff. There is no doubt there is some man made urine out there. That has been going on for a while.

If you can't detect the "target animal odor" in the under tone base odor I would be suspicious as to its authenticity or quality.

He is, and it is the best stuff you will get, but he does not ship. Pickup only. Johnny collects some great stuff in Indiana too and will ship

Is that 1 leg Johnny? If so what is address. Dr. Bob swears his is good stuff also.

X4. The Private Stock is what I've used for 3 years now.

When I started I used to by great urine from Nelson, Bierman, and then Carman and Mr. Grawe. I am a guessing that you cannot contact these folks anymore. You could trust these guys.
I never got anything but top quality stuff from Jamison.
Never tried some of the other top names mentioned here.
But I suspect if Derrick, The Big O or Reuwsaat had any for sale you could surely trust them.
There is some dude with one leg or one arm that is supposed to be a good collector but I don't know the name or contact information.

Yes. I will send you a pm
