Section 1
How the price score was made

One figure decides the rank: the middle of this store's price ratios, each price per mg against the median for the same peptide in the same format. The same code ranks every store; see the method.

  1. Prices compared

    standard size, like with like
    9prices

    9 prices of Barn at the standard size1, each divided by the median price per mg of the same peptide in the same format across the 111 stores on file2: 9 kits against the kit median.

    The "vs median" column under prices per mg shows each ratio.

  2. Price index

    the middle ratio
    0.80index

    1.00 is the median price for the format; lower is cheaper. The ratios from lowest to highest, to two decimals:

    0.65, 0.76, 0.79, 0.80, 0.80, 0.83, 0.85, 0.87, 0.91

    The middle value, the 5th of 9: 0.800.

  3. Price score

    out of 100
    66.1of 100

    On the doubling scale, 100 at an index of 0.5 or less, 50 at 1.00 and 0 at 2 or more: 100 × (1 - log2 0.800) ÷ 2 = 100 × (1 - (-0.322)) ÷ 2 = 66.10, rounded to 66.1.

Section 2
Barn prices per mg

Cheapest in-stock listing per peptide1. The standard size is the vial size most stores sell; only those prices are compared. "vs median" is the price per mg divided by the median for the same peptide in the same format: a kit (2 or more vials) against the kit median, a single vial against the single-vial median2. A format that fewer than 3 stores sell is not compared. A kit is never counted dearer than typical when its price per mg is at or below the single-vial median, and never dearer than a single vial at the same price per mg above it.
