In your opinion who sells the highest quality urines?

Artificial or natural or best quality imitation?

Real deal natural

Hawbaker's has good fox urine.

Is that still the case since it's changed hands?

I've heard a fella named Bob sells the best.

I bet there is a hundred good pee threads here...

I'm sure there is. Now here's another

Who makes a synthetic or imitation urine? Reason I ask is there was a post on Facebook where someone was trying to say good urine never has an ammonia smell

I don't know who makes it but there a couple of examples of fake fox urine for sell, I think Home Depot sells some too. There used to be a big lure ingredient supplier back east, NJ iirc, that advertised it. I can't recall the name because it's been years since I was interested making lures. Here's a 1995 study of how synthetic predator urine works as a deterrent, so the use of synthetics ain't a hogwash idea.

Interesting that a search of synthetic urine turns up hundreds of ads for fake human pee and how to fake a drug test and yet we think no one would market fake fox pee.

But all pee has ammonia which I understand is a normal product of the metabolism of protein. Certain diets or dehydration might cause your urine to smell strongly of ammonia. Normally the ammonia trapped in a bottle of urine should gas off fairly quickly.

the problem isnt that there is a LOT of fake pee being sold, the problem is the dealers who market it as genuine.

truth in marketing? kinda a novel idea.

I am curious about what I have that I purchased. I will leave the name out of it as i don't know too much about fox urine. I got a quart of red fox urine this year from someplace i always get good supplies and items from. IT smelled good and looked good. In a cold spell at the beginning of the season the bottle and all urine in it froze. fairly solid froze not just slushy. It was -13 one night not that that makes a huge difference to me i guess. What I am saying though is now the urine has a different odor all together. After noticing that i paid attention the the temp and it and noticed it starts freezing just below 32 degrees. I had thought good urine froze a lot lower temp than straight water. I have also never had my urine change smell and make up on me after a freeze. I am however not very intelligent on the origin and base of urine bought. I guess i just thought when anyone bought urine they got 100% actual urine.

Could of been cut with water or the animals were overhydrated. Stuff being cut has been going on since the lure/urine business began.

Internet says normal human urine freezes at -1C to -5C or ~23-30F, so it would be unusual for a solution of various salts and urea to freeze at 32F. Add water the freeze temp gets closer to that of water.
I have read though that many urines have additives to lower the freeze point. One famous lure maker and trapper posted on this site some years ago "I add a cup of pickling salt per gallon of urine as an anti-freeze during winter trapping and have never noted salt compromising the urines effectiveness whatsoever. Salt is natural.."
It's been said that when urine is partially frozen you can remove the ice and the remainder will be more concentrated and will also be more freeze resistant.

Human urine is as good as varmint urine anyway. Cheaper. Cheaper is better. LOL.

I don't think there is much difference chemically, the exception being the hormones and shed cells and they might affect the odor.
