b12 injection solution. must read
I got this off a doctor's website. here's his article http://www.autismweb.com/_disc/000011ac.htm
but the best part is this one.
Once I decided to use injectable methylcobalamin, the next dilemma that needed to be addressed was whether to use the intramuscular, intravenous, or subcutaneous route of administration. Initially I used both the intramuscular and/or subcutaneous routes. However, within 6 to 8 weeks it was my "impression" that I was getting a higher response rate in the group of children that were using the subcutaneous route of administration. Hypothetically, subcutaneous injections may produce a "slow time-release" process, allowing a "leaching effect" of the methylcobalamin. This theoretically could allow a "relatively higher dose" of the substance to remain in the body for longer periods of time if this was compared to the in intramuscular or intravenous routes of administration. One reason for this is that the kidneys are known to quickly clear any excess cobalamin. Because cobalamin is a red substance, I have occasionally been called by panicking parents reporting "red urine" in their child’s urine who were worried the child was bleeding. I have never seen red urine with the subcutaneous route of administration but I have seen it infrequently with intravenous and intramuscular administration.
