You can buy vitamin B12 injections online from a pharmacy and administer the injection for yourself if you know how to do it safely
Obviously this ignores all those who require life long treatment due to other causes of B12 deficiency (of which there are many), thereby potentially causing great harm to the vast majority of their B12 deficient patients
How CoLaz approaches B12 injections At CoLaz, B12 injections are given by trained clinicians after a written consultation that reviews your history, symptoms, medications and (where the picture warrants it) an NHS blood test through your GP
Common mild side effects: injection site soreness (1224 hours, resolves without treatment), brief warmth or flushing immediately after injection, occasional acne with regular use
The whole appointment is usually over in less than 15 minutes
