I'm using it topically, would this required more than oral use?
Also, I've noticed my skin has become kind of yellow, which I associate with liver problems (?) and I kind of had this skin tone back when I was "paleo" and eating 1lb+ of beef kidneys liver and heart per day.
way too much copper. Reasonable amount is around 2-4mg per day with 20-30mg of zinc. Only 100g of beef liver has around 29mg!!
