Cytochrome P450 2E1 (CYP2E1) mRNA is not reduced by GHK-Cu (RT-qPCR: P=NS), indicating protection is downstream of NAPQI generation consistent with Nrf2-driven GSH replenishment and antioxidant enzyme upregulation rather than reduced toxic metabolite production

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
