Depends on the specific conditions but less than 2mA for AC should only be a tingle and closer to 5mA for DC will be a slight tingling.

Yep, and even with AC, it depends on the frequency. There are a ton of variables affecting how dangerous electricity is to people, so it's hard to make general statements about it.
