Where they actually differ

  • They bill on different clocks. Emerge Weight Loss charges every 4 weeks and Willow charges every calendar month. That alone changes what a “month” costs, which is the whole reason this index recomputes every price.
  • One price holds and the other climbs. Emerge Weight Loss’s price is a starting-dose price that climbs; Willow’s is not stated. See what titration does to an advertised figure.
  • What they advertise is not what they bill. Emerge Weight Loss advertises $224 and bills $244.
