Where they actually differ
- They bill on different clocks. altRX charges every calendar month and Pepti charges every 4 weeks. That alone changes what a “month” costs, which is the whole reason this index recomputes every price.
- One price holds and the other climbs. altRX’s price is the same at every dose; Pepti’s is a starting-dose price that climbs. See what titration does to an advertised figure.
- What they advertise is not what they bill. Pepti advertises $99 and bills $108.
How we know

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