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.
