Where they actually differ
- They bill on different clocks. Strut Health charges every 30 days 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. Strut Health’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. Strut Health advertises $149 and bills $151.
How we know
Both figures were read on the seller’s own site and recomputed over a 30.4375-day calendar month from the charge and the billing period it covers. Neither is a seller’s own “/mo”. The full working for each — the charge, the period, the arithmetic and the date it was read — is on its own page: Strut Health and Willow. The method is set out in how we verify.
