Has anyone ever heard of or tried this?

“After the enema, we insert a little unscented deer tallow into the anal. It makes the walls of the rectum and intestines slippery even if the standard lubricant gel dries. Deer tallow also remains after training and helps heal tissue. ”

It cost about 50€ per kg, so it doesn't seems over expensive (2L of IDGlide is 80€, 0.5L is 35€)

Thanks
