How decanting works

1. Buy the low doses. Put in GE buy offers at the "Buy at" price — 1 gp over the insta-sell, the offer most likely to fill first. Making one 4-dose takes four 1-doses, two 2-doses, or four 3-doses per three 4-doses.
2. Decant for free. Talk to Bob Barter at the north-west corner of the Grand Exchange — he combines your potions into 4-dose instantly, free, and works on noted potions, so you never have to leave the GE.
3. Sell the 4-doses. List them at the "Sell at" price — 1 gp under the insta-buy. The profit column already has the 2% GE tax taken out.

Only routes that are profitable after tax and trading briskly enough to actually fill are listed — a juicy-looking margin on a potion nobody trades isn't real, so thin, stale-priced or price-spiking routes are hidden. The per-hour column assumes you capture a realistic slice (about 15%) of what the route's recent trade volume supports, capped by the buy limit (how many source potions you can buy per 4 hours) — you share the route with everyone else working it. Leftover empty vials are ignored (they're worth a few gp each).
