Combat potion(3)

The Combat potion(3) is a members-only Old School RuneScape item — “3 doses of combat potion.”. Its Grand Exchange buy limit is 2,000 per 4 hours. Right now it buys at 146 gp and sells at 145 gp — a net margin of -3 gp (-2.1% ROI) after the 2% Grand Exchange tax of 2 gp. High alchemy yields 96 gp.

To flip it, place a buy offer near 146 gp and a sell offer near 145 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
