  "methodology": "Pure L-citrulline is 100% citrulline. Citrulline malate is only part citrulline; we use the GENEROUS theoretical-max fraction (2:1 = 72.3% by moles, 1:1 = 56.6%) — note that independent NMR testing (Chappell 2018, PMID 30097067) found commercial \"2:1\" products delivering as little as ~53%, so real malate figures are likely higher-cost than shown. Actual citrulline grams per container = servings x compound mg per serving x fraction / 1000. Cost per gram = live Amazon price / actual citrulline grams. Cost per 6 g dose = cost per gram x 6 (a clinical reference dose).",
