Hi everyone, I have been ordering methycobalamin in powder form from a lab in the UK. I get it in this form because b12 loses potency when water is added and it's exposed to light. So I get the powder in vials, add saline solution, and do intramuscular injections.
This worked very, very well for me for over a year. However, the source of the methycobalamin went out of business, and the lab I order from started using a new source. My health immediately went downhill and it took about 6 months to get the lab to admit the source change.
My question is: is anyone out there ordering very high quality, sterile, medical grade, methylcobalamin powder for injections? If so, please message me.
Failing this, I have to start the highly unpleasant task of trying out Chinese suppliers in hopes of finding something of the highest quality. I don't know where else to look at this point....Thanks!
