Ant Nectar

Ant Nectar is a chem produced by giant ants and can be obtained looting dead giant ant corpses.

It's relatively rare, being found in piles of Ant Refuse Pile, and also in Rivet City in the shop known as A Quick Fix, run by Cindy Cantelli. There are some of them being exposed, but taking them makes you lose karma. Cindy also sells them.
