So i have been trying some stuff but can't think of a way to create a potion that never ends. Splash or not im having trouble. What i want it to do is be a potion of poison that when it is thrown it does not leave your inventory kind of like duplicating. so you can throw it any number of times. Thing is i want it to only be that specific item not every splash potion.

on 1.14

/execute unless entity @a[nbt={Inventory:[{id:"minecraft:splash_potion",tag:{Potion:"minecraft:strong_poison"}}]}] run give @s splash_potion{Potion:"minecraft:strong_poison"} 1

in an repeating commandblock

************EDIT***********

sry too fast not working

First, create a scoreboard objective with

/scoreboard objectives add infinite_potion dummy

Second, give a tag to the player(s) that should have an infinite amount of potions:

/scoreboard players set <Player Name> 1

(I think it's also possible to do it dynamically, with detecting the players that have the potion but you would be unable to put the potion e.g. in a chest and I don't have enough time to solve that at the moment.)

Then you can use the command from romanorose76

/give @a[scores={infinite_potion=1},nbt=!{Inventory:[{id:"minecraft:splash_potion",tag={Potion:"minecraft:strong_poison"}}]}] splash_potion{Potion:"minecraft:strong_poison"}

in a repeating command block to refresh the splash potion (I didn't test it but I think it is working).

Of course you can also give the player another splash potion (check Minecraft Wiki).

The potion will always be in the first hotbar slot, you can also give it to another slot by altering the /give command but it will be static.

Hope I helped you.

Best way to achieve this is to set a scoreboard to test if a player has thrown a splash potion-

First set up the scoreboard:

scoreboard objectives add thrown minecraft.used:minecraft.splash_potion

Then check for potion throw and replace main hand slot with potion (run this in a repeat command block)

execute as @a[scores={thrown=1}] run replaceitem entity @s weapon.mainhand splash_potion{Potion:"minecraft:strong_poison"}

Then reset the score(in chain, conditional command block):

execute as @a[scores={thrown=1}] run scoreboard players set @s thrown 0

never mind..
