Vitamin B12 Injection
The one injection we can give you the same day
Plain cyanocobalamin — an FDA-approved, manufactured injectable, not a compounded blend. Because it is a finished drug product bought from a licensed wholesaler rather than compounded for one patient, our clinic is permitted to hold it in stock. It is the only injection on this list we can give you without waiting for a pharmacy to fill it in your name.

FDA-approved finished drug product.

Weekly to monthly injection

Please read
- We check your B12 level before starting. Injecting B12 into someone who is not deficient does not produce the energy benefit often advertised.
- Given from clinic stock under lot-number tracking, as an FDA-approved manufactured product.
