a friend told me he urinates out of his deer stand and it doesn't affect deer and it's biologically proven that there is no difference in deer urine and human urine.
I did an experiment a few weeks ago. I urinated into a scrape that was being regularly used, and kept an eye on it for a couple of weeks. Bucks returned to the scrape and carried on scraping activity there. Next year I'll do it again, and put a trail camera there. I don't think the smell of urine is negative to animals, and it sometimes is positive if they're looking for companionship (herd instinct) or opportunities to breed (reproductive instinct).
I can't say there is no biological difference between deer pee and human pee, and I don't know how that could be proven outside a lab. But I can say I believe your friend when he says it doesn't affect deer in a negative way.
I can also say, "Welcome to the D&DH forums, Todd!" I hope this is only your first of many good posts.

isn't hunting, he's thinking about hunting, talking about hunting, dreaming about hunting, writing about hunting, or wishing he were hunting.
