Buy OSRS Extended stamina potion(4)

Description

The Extended stamina potion(4) is a members-only potion in Old School RuneScape. Each dose restores 40% of your run energy. It also cuts run energy loss by 70% for 4 minutes. This lets you run much longer without stopping to rest.

The effect does not stack. If you drink another dose while the timer is active, it just resets back to 4 minutes. While the effect is on, the boot in your run energy orb turns from yellow to orange.

This potion works well with the ring of endurance. Each dose gives the ring two charges. If you drink a dose while wearing a charged ring of endurance, it uses 2 charges to double the effect. You get 80% run energy back and the run energy buff lasts 8 minutes.

Players with level 85 Herblore can make this potion by mixing a regular stamina potion with marlin scales. Each dose gives 27.5 Herblore experience and needs one marlin scale.

The potion was released on 19 November 2025. It is tradeable and noteable, but not equipable or stackable. It weighs 0.03 kg.
