PX Syringe is a lightweight NeoForge mod that lets players load potions into syringes and inject potion effects directly into themselves or other living entities.

The mod uses Minecraft’s standard potion component system, allowing compatible potions from other mods to work automatically.

Features

Load any compatible potion into a regular or Netherite Syringe.
Filling a syringe does not consume the source potion.
Right-click to inject yourself.
Shift + Right-click another living entity to inject the target.
Works on players, animals, villagers, monsters, and bosses.
Effect immunity still follows vanilla Minecraft and the rules of other mods.
Effects are applied immediately.
No splash radius, lingering cloud, or additional injection particles.
Supports potions containing multiple effects.
Supports compatible modded potions.
Includes a dedicated PX Syringe creative tab.
Includes English and Simplified Chinese translations.
No additional dependencies are required.

Regular Syringe

Regular Syringes are single-use items.

Craft one Iron Ingot, one Glass block, and one Piston together in any arrangement to receive 16 Syringes.

After injection, the potion keeps its original effect level and duration, and one Syringe is consumed.

Netherite Syringe

The Netherite Syringe is an end-game reusable upgrade.

It permanently stores its loaded potion, has unlimited uses, has no durability, and has no cooldown.

All non-instant effects applied by a Netherite Syringe receive infinite duration while retaining their original amplifier. Instant effects, such as Instant Health and Instant Damage, still activate only once.

Infinite effects can still be removed normally by milk, death, or commands.

Craft one Netherite Ingot, one Glass block, and one Piston together in any arrangement to receive four Netherite Syringes.

Loading Potions

Combine an empty Syringe with any compatible potion to create a filled Potion Syringe.

The source potion is not consumed, allowing the same potion to fill multiple Syringes.

Emptying a Netherite Syringe

Place a filled Netherite Syringe by itself in a crafting grid to turn it back into an empty Netherite Syringe.

The stored potion is discarded and no potion bottle or empty bottle is returned.
