Self-Administration Training and Protocols For those needing long-term Vitamin B12 injections, self-administration training is often necessary

Pharmacokinetics: Cyanocobalamin is administered intranasally, orally, and parenterally, while hydroxocobalamin is administered only parenterally. Once absorbed, vitamin B12 is highly bound to transcobalamin II, a specific B-globulin carrier protein and is distributed and stored primarily in the liver as coenzyme B12. The bone marrow also stores a significant amount of the absorbed vitamin B12. This vitamin crosses the placenta and is distributed into breast milk. Enterohepatic recirculation conserves systemic stores. The half-life is about 6 days (400 days in the liver). Elimination is primarily through the bile; however, excess cyanocobalamin is excreted unchanged in the urine

It's a good idea to start changing your habits before getting your first injection

When NNMT is active, fat cells become metabolically lazy. By blocking it, this peptide reactivates fat cell metabolism, increases NAD+ availability in adipose tissue, and essentially flips a switch from fat-storing to fat-burning at the cellular level
