Where found
Gladst is purchasable for from the Klingon Chef (Deep Space 9). It has been found in diverse locations, and should not be assumed to be particularly associated with Klingon missions. Amongst the more unusual places it turns up — for Federation players, at least — are the Romulan/Reman mission and ground missions in the Delta Volanis Cluster. Because of the unpredictability of its appearance, it tends to be a pricey item on the exchange — when and if it actually appears there.

A high enough quality Klingon chef will allow you to replicate it for 20.
