The unification of gauge interactions in the context of adjoint SU(5) and its phenomenological consequences are investigated. We show the allowed mass spectrum of the theory which is compatible with proton decay and discuss the possibility of having a cold dark matter candidate. Because of the upper bounds on the proton decay partial lifetimes, \ensuremathτ(p\ensuremath→K+\ensuremathν)\ensuremath≤9.3\ifmmode×\else\texttimes\fi1036 years and \ensuremathτ(p\ensuremath→\ensuremathπ+\ensuremathν)\ensuremath≤3.0\ifmmode×\else\texttimes\fi1035 years, the theory could be tested at future proton decay experiments. The theory predicts also light scalar color octets which could be produced at the Large Hadron Collider.
