On mobile an ascendant quality prod with 4 damage can deal ≈ 1740 torpor, but...that's about it. 1740 is roughly 750% according to dododex, and a 750% longneck deals around 1650 with normal tranq darts. Plus it's ranged. And multiple use. And easier to find. And cheaper. So...yeah. I don't see why you would ever need this thing. If you really do want to try one out, you can find higher quality prods in the red lootbox in cave of the strong.

You can only use this for one strike before having to repair it in a fabricator.
