Took 10 bicillin shots in a 12 day period. Then continued once a month for a year. Missed 2 or 3 shots due to Hurricane K. The proticol really helped with brain fog and much of the joint and muscle pain. The injection has to be Bicillin CR 900/300. The 300 number refers to the units of procaine which help make the shot almost painless. Unfortunately, my LLMD was ederly and died before I could get back to him. I did go to another Dr. who gave me bicillin but it was a different mix and hurt very much. So, Iam trying to aDr. who will duplicate the first protical.
