With that in mind here are the injection sites you can use on your body for B12 shots: Mid-thigh (right into your quadriceps): This is the preferred site if you are self-injecting
As with virtually all research peptides, use during these periods is not recommended

The injection provider can administer the B12 shot deep into the muscle (intramuscularly) or into the tissue layer between the skin and the muscle (subcutaneously)
This allows your skin's pH to normalize after acidic vitamin C and reduces interaction potential
