Yeah. I've seen some split between low vs high doses, where the first two doses cost less than the rest - a cynical take is that they want to make it cheaper to get started knowing they will get you hooked possibly for life, or at least the duration of their patent.

But yes, non-linear by design - a 15mg dose provides 6x the medication but cannot be sold for 6x the price or people will stay on lower doses (or discontinue) rather than going to a higher dose.

Meanwhile it provides 6x the medication. One multi-use 4-week pen has enough to provide 12 weeks of doses at 4-week titration if used off-label. Obviously this is only helpful on low doses.

Important note: I am not a doctor, I don't recommend doing this - in fact, I have not done it myself and will probably not do it in future. I have seen YouTube videos of medical professionals explaining how to dose split weight loss drugs though.

I would highly recommend dose splitting the brand name drug over picking some compounding pharmacy's version of the drug, or worse, buying it off the street. It's crazy though, there are even counterfeit medications in the supply chain sometimes, for example: https://www.fda.gov/drugs/drug-safety-and-availability/fda-w...
