Where they actually differ
- They bill on different clocks. Collective charges every calendar month and Fifty 410 charges every 3 months. That alone changes what a “month” costs, which is the whole reason this index recomputes every price.
- One price holds and the other climbs. Collective’s price is the same at every dose; Fifty 410’s is a starting-dose price that climbs. See what titration does to an advertised figure.
- Only one carries a mandatory recurring fee. Collective: $17 a month. 360 of 382 sellers charge nothing like it.
- What they advertise is not what they bill. Collective advertises $69 and bills $86.

The full working for each — the charge, the period, the arithmetic and the date it was read — is on its own page: Collective and Fifty 410. The method is set out in how we verify.
