We present a summary of recent results obtained from a scan of the 19-dimensional parameter space of the pMSSM and its implications for indirect dark matter searches. In particular, it is well-known that the MSSM cannot accomodate the recent anomalies observed by PAMELA and Fermi without the incorporation of a rather large boost factor of order 1000. We combine a scan over the astrophysical parameters that compute the standard cosmic ray background flux (via GALPROP) with our scan in the pMSSM, and find that we are able to fit the data with sizeable excesses over background in the positron spectrum and no corresponding excess in the anti-proton spectrum with a much lower boost factor.
