Peptides are proteins, and in a person with the genetic potential to overreact to invading proteins in the blood (gluten is one example)...you can react to your own if they are found floating around like an invader, and not attached to where they belong.
It is one theory for some viral illness triggers for PN.
This is not common, and no one yet has proven the theory but some doctors will cite it to patients when other answers are negative.
B12 injections are typically cyano form, and for those who have the methylation genetic errors is not going to work as they cannot activate to methylcobalamin for the B12 to be in it active form.
Better to take methyB12 orally for a while and see if that improves things. At least 1mg a day on an empty stomach.
