Jesus christ there you have it. I swear on my mothers grave if you start taking copper you will feel a lot of improvements. The copper toxicity is a myth. Your body has a mechanism of excreating extra intake through your bile. Toxicity is for people with hereditary genetic diseases causing your body not to produce ceruloplasmin. upper safe dosage is 10mg per day. I've done 16mg a day with no problem only seeing benefits since to was also copper deficient at one point. Buy a chelated copper supplement like copper glycinate and start taking 4mg a day with food to avoid nausea and you'll see within a month you're aches will be gone. You probably notice improvements after first dose.
Do yourself the favor
How about the zinc ratio and when did you feel improvement?
My Ceruloplasmin was a bit too low too
