Summary

This study checks whether a new methylconalamin injection works the same as the standard version in 20 healthy adults. Each person gets both injections at different times, with a break in between, to compare how the body absorbs them. The goal is to see if the two are bioequivalent, meaning they can be used interchangeably.
