We remark that the precision of recent determinations of αs(M2Z) is such that one can get bounds on supersymmetric partner masses (squark and gluino) by requiring consistency of determinations of αs at "low" energies, where those particles do not contribute, and on the Z peak. For approximately degenerate squarks and gluinos with mass \widetildem, we find the bound \widetildem≥ 173 GeV, at the 2σ level. At the 2.5σ level, \widetildem≥ 121 GeV.
