Potion Decanting

Buy the cheapest doses, decant them up to (4) with Bob Barter at the Grand Exchange (free, members only), then sell the 4-dose. Profit / (4) is the margin on a single potion; the RS Score is the realistic total profit — it weighs that margin against how many doses actually trade (and the GE buy limit), so a fat margin you can only buy 12/day of ranks below a thinner one you can buy thousands of. Expand a row to see each dose (1/2/3) and how buying them together stacks up. Prices are 4-hour averages. Click a column to sort.
