We study the following nonlocal mixed order Gross-Pitaevskii equation
 $i\,\partial_t \psi = -\frac{1}{2}\,\Delta \psi+V_{ext}\,\psi+\lambda_1\,|\psi|^2\,\psi+\lambda_2\,(K*|\psi|^2)\,\psi+\lambda_3\,|\psi|^{p-2}\,\psi,$
where
 $K$
is the classical dipole-dipole interaction kernel,
 $\lambda_3>0$
and
 $p\in(4,6]$
; the case
 $p = 6$
being energy critical. For
 $p = 5$
the equation is considered currently as the state-of-the-art model for describing the dynamics of dipolar Bose-Einstein condensates (Lee-Huang-Yang corrected dipolar GPE). We prove existence and nonexistence of standing waves in different parameter regimes; for
 $p\neq 6$
we prove global well-posedness and small data scattering.
