Does compounded tirzepatide contain vitamin B12?

This site does not know. Compounding-pharmacy marketing sometimes mentions B12, glycine, or other add-ins, and those claims are not in this catalogue. Legal-status fields record country-level approval for tirzepatide, not the extra ingredients in a compounded vial. An approved Mounjaro or Zepbound pen is a finished labeled product; a compounded vial is a different article. This FAQ does not invent a B12 formula, does not name a vendor, and does not treat a marketing line as a measured composition.
