yeah i kind of wonder why they use animal urine instead. i mean, ignoring the mental ick factor, why not replace with the real thing? human hormone for human hormone? i can see how consumers might be grossed out if they knew it was human urine but then again horse pee isnt very appetizing either. *wry smile*
i wonder if it's a chemical stabilizing problem? ah! or, more likely, maybe it's an ease of quality control thing? i imagine horses would be a little more willing than most humans to devote their full time to living just so, all to be a good spigot for mass consumption *L*. the horse pens would help with that i guess.. *smile*
*just thinking aloud*
