Cost per milligram, on a logarithmic axis: each labeled step is ten times the one before it, because the routes are that far apart. Positions are this site’s arithmetic from prices read by hand on the dates shown in the table below, where the division behind each figure is printed.
These 18 prices from 10 sellers state enough to calculate a cost per milligram. An IV milligram and an oral milligram are different purchases; this comparison does not establish equivalent treatment.
233 of 345 distinct prices state no dose; a further 55 cannot be turned into a total. See why those prices are excluded.
