Why presentation changes the comparison
Cost per milligram is calculated from the strength printed on the listing. Where a listing states no strength the column is left blank rather than estimated. Two GHK-Cu listings at the same headline price are not comparable if one is a lyophilised vial and the other a pen already in solution.
