Cost-Per-Dose Calculator
The price on the vial tells you almost nothing. What matters is the price of one dose, how many doses are in there, and whether the bigger vial is the better buy once postage is counted. This works all three out.
Then it does the part people skip: the full run. Enter how long you intend to keep going and you get the number of vials and the total bill, before the third re-order is the thing that ends the experiment.
Compare sizes and sellers
Add a row for every option you're weighing up. Same dose and schedule applies across all of them, so you're comparing the product rather than two different protocols. A larger vial is very often cheaper per dose even when the sticker price is higher, and this is where that becomes obvious. "Full run" uses the doses/week and weeks fields above — fill those in to see it.
