I learned from the site that I can just go up to 4 mcg … I could not take eight clicks or 80 µg…. The pain in my feet and hands were unbearable. But I’m doing great on the 4mcg ….. When I try to go up even to five I still getting the pain then I have to wait a week or two with nothing and then start again so I’m just proceeding with the four MCG’s and will do a bone density soon to see if it’s working…. I’m only 411 in height and 105 pounds so hopefully that’s enough dose for me
