The aim of this work is to use full evolutionary models to derive observational constraints on the mass loss rate of the upper Asymptotic Giant Branch (AGB) stars. The observations used to constrain the models are the relative number of luminous Lithium rich AGBs in the Magellanic Clouds and the s-process enhancement of the same sample. We find that we can put lower and upper limits to the mass loss rate during the AGB phase. The mass loss calibation obtained in this work implies that massive AGBs do not contribute significantly to the lithium enrichment of the interstellar medium.
