So, for next season, I want to attempt to make a red fox gland lure to try out myself. I have some glands from reds I caught that have been aging for about 3 years, and I also have a bunch of frozen bladder urine that I have collected. My question is, do I have to do anything to the urine before using it in a formulation? I know I saw clint locklears lure video he poured urine over ice in a coffee filter to pasteurize? it, and wasn't sure if something like that needed done to it or not?

In my opinion you can use the bladder urine as-is.

Glycerine will help freeze proof it and it acts as a humectant to keep the lure from drying out.

Awesome, thank you. Was hoping you'd respond, saw your homemade glad lure video on YouTube the other day and it got me really inspired!
