Subcutaneous Vitamin B12 Injections Wash your hands with soap

(Mills et al., 2016) found nicotinamide mononucleotide (NMN) supplemented in mice decreased body weight and increased insulin sensitivity as well as improved plasma lipid profile

Research shows injectable B12 achieves serum concentrations 40x higher than equivalent oral doses in deficient patients, explaining its superior clinical outcomes for severe cases

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

Heres the problem: I could not find a single primary study showing 5-Amino-1MQs effect measurably diminishing after any number of weeks
