where do you inject b12 in the thigh to Vitamin How to self-inject intramuscular vitamin
Description
It's 1ml Yes , but 1.5mg( or 1500mcg as they express it ) 50% more B12 content than Rotexmedica It looks as though you chose the Pascoe ampoules 1.5 mg ampoules ( Nackapan pointed this out ) These are not so popular as Rotexmedica , so it might be that that pharmacies dont shift this brand as quickly as the Rotexmedica ., dont have such a fast turnover
