i found this on the research chem site i ordered my caber from

Cabergoline is a white powder soluble in ethyl alcohol, chloroform, and N, N-dimethylformamide (DMF); slightly soluble in 0.1N hydrochloric acid; very slightly soluble in n-hexane; and insoluble in water.

the caber they sell is an aqueous solution. so this means that their product will settle at the bottom. will shaking the solution up before you draw it be good enough to mix the solution to get a dose accurate enough.
