  The pressure and energy density of the quark-gluon plasma at finite baryon
chemical potential are calculated using the Complex Langevin equation. The
stout smearing procedure is generalized for the SL(3,$\mathcal{C}$) manifold
allowing the usage of an improved action in the Complex Langevin setup. Four
degenerate flavors of staggered quarks with $m_\pi=500-700$ MeV are used with a
tree-level Symanzik improved gauge action on $16^3 \times 8 $ lattices. Results
are compared to the Taylor expansion and good agreement is found for small
chemical potentials.
