Where they actually differ
- They bill on different clocks. Shape Vantage charges every 3 months and WeightRx 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. Shape Vantage’s price is not stated; WeightRx’s is a starting-dose price that climbs. See what titration does to an advertised figure.
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: Shape Vantage and WeightRx. The method is set out in how we verify.
