Does compounded tirzepatide contain vitamin B12?

This site does not know. Compounding pharmacy ads sometimes mention B12, glycine, or other add-ins, and those claims are not in this catalogue. Our legal 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 product. This FAQ does not invent a B12 formula, does not name a seller, and does not treat an ad as a measured recipe.
