"The passive on-hit damage does apply lifesteal, leading this item to have more sustain, in most cases, than a fully stacked   The Bloodthirster.

Disregarding the active ability and attack speed, to exceed damage gained by a fully stacked   The Bloodthirster  on a target, the target must have at least (100-25)/(0.05) = 1500 health. To deal more average damage to a target than a   The Bloodthirster  from full to no health, the target must have over 3000 health."

This information is outdated. BotRK has a flat amount of lifesteal now. The on-hit proc doesn't heal you anymore.
