I couldn’t verify an exact duration for stims in Project Delta from the available info, so I don’t want to guess. The only directly relevant source I found is the game’s wiki entry for stim-related items, but it doesn’t state a clear timer there.

What I can say

  • Stims in Roblox survival/FPS games usually have a short, temporary effect rather than a permanent buff.
  • In Project Delta , the exact duration appears to depend on the specific stim type and any recent balance changes.
  • Community posts and short clips reference purple stims, but they don’t provide a reliable, consistent duration.

Best practical check

  • Look at the stim’s in-game description or inventory tooltip.
  • Test the effect in a safe area and time it with a stopwatch.
  • Check the current wiki pages and recent community posts, since these games often change effects in patches.

Answer in one line

I can’t confirm the exact length from the sources I found, but it seems to be a temporary buff whose duration varies by stim type.
