BioHack Track models Vitamin B12 (Methylcobalamin) at a half-life of 144 hours, so every dose you log is decayed against that curve and the app shows what is still circulating — not just what you typed.
Injectable forms are pre-mixed; oral/sublingual need no prep.
Refrigerate injectable vials; protect from light.
Very low toxicity risk since excess is excreted, but energy/mood benefits in people who aren't deficient are not well supported by evidence.
