I have done B12 injections from AgelessRX for a few months now. I never had a reaction, never turned red at the injection site, never itched, etc. I recently started B12 injections from ampoules I have gotten from B12supplies. This is my 3rd injection from their stock and I react the same way each time. The injection site burns after injecting, the redness spreads, and it itches insanely bad. The photo is what the injection site looks like after 2 days. It takes about a week for the redness and itchiness to go away. I have tried my leg and my stomach and it’s the same reaction each time. Does anyone have this with B12supplies?
