Cost per delivered dose, which is the number that matters

Cost per delivered dose, which is the number that matters — setting out what I have, and where I think it stops being reliable.

Documenting an access outcome, dated, because everything in this category expires.

As of May 2026, in my region, the position is as described below. I have linked the primary source rather than a summary of it, because the summaries are consistently a year behind.

If anyone can confirm or contradict this for their own region, please date your answer. An undated claim in this category is worse than no claim.

Taking the opening post at face value and following it one step further.

Where somebody posts a comparison, the useful version states the date, the region and what was included.

The honest answer is that it depends, and here is what it depends on.

Cost per milligram is the only comparison that survives format differences, but even then it needs care. A pen and a vial are not the same product and cannot be compared on price per milligram alone because dead volume, wastage, and number of doses actually obtainable differ.

Worth separating two things that post #3 runs together.

Nothing here is financial advice and none of it is a route to a transaction.

Same conclusion as the reply above, reached differently, which is mildly reassuring.

This follows post #3 rather than contradicting it.

Wastage from a concentration choice that leaves an unusable remainder is a real cost and is invisible in a per-milligram figure.

That is what I would do. It may not be what is correct.

A cheaper option that arrives slowly has a cost in the form of running out, and people rarely price that.

The most useful pricing posts here are the ones that show the arithmetic rather than the conclusion.

Cost per week at a maintenance dose is the figure most people actually want and least often calculate.

That is one dataset and I would not build a rule on it.

A pen and a vial are not the same product. Dead volume, wastage and the number of doses actually obtainable all differ.

Post #8 is the version of this I will quote in future. One addition.

The cost of an independent submission is worth stating in these threads, because it is the main reason people do not do it.

Useful. I have added it to my own notes with the date on it.

Insurance tier placement: a compound might be covered but on a higher tier (higher copay). Moving to a lower tier usually requires prior authorization or documented failure of cheaper alternatives.

Written in the hope of being told what I have missed.

Compute cost per delivered dose at your dose if you want a number you can act on. That requires knowing your dose, vial volume, and whether you are using a vial or a pen.

I am reporting what happened, not recommending it.
