Subcutaneous B12 administration, although promising in select cases such as congenital cobalamin disorders, lacks comprehensive comparative studies against IM and oral routes
The product is likewise indicated for increased physiologic demand (pregnancy, thyrotoxicosis, chronic hemorrhage), for drug-induced depletion, and for select neurologic or hematologic disorders in which B12 plays a pivotal metabolic role

An injection bypasses this process, ensuring you get the entire dose effectively every time
Heres the key part: Do not inject the water directly onto the powdered peptide cake
Notably, newborn infants are at risk of severe toxicity (as discussed in Contraindications), but in adults and older children, the small benzyl alcohol dose is very well tolerated
