Thanks for the information. I am worried about the cost as well seeing how I have spent so much on medical bills and supplements already. I had to pay $30 shipping since the GSH had to stay cold. I explained to my doctor in order to keep ordering it would have to be larger doses at once, I can not waste $30 on shipping all the time. I did smell some fragrance a few minutes ago and I could tell I had inflammation (this is what happens to me, like my neck clicks first..) so I used the b12 spray and my neck stopped clicking within 10 min.
