the parametrized mass. Yet, within the lines of the later, Znojil [43] in his mass- sign duality proposal, has observed that the non-Hermitian cubic oscillator’s Hamiltonians H$_{±}$ = p 2 ± m $^{2}$x2 + ifx 3 with opposite sign mass signatures are (up to a constant shift) isospectral. For the feasibly significant role it may play, the mass term should always be kept intact with the associated Hamiltonians, therefore. Finally, as long as our non-Hermitian PT -symmetric Hamiltonians H$_{PT}$ find their Hermitian partners ( not necessarily isospectral neither necessarily PT - symmetric) in the Hilbert space (where boundary conditions and consequently orthonormalizability are feasibly very well defined), either through a simple transformation toy (13) or a similarity transformation toy (23) accompanied by a mass parametrization recipe (9) and/or an analogous coupling constant recipes, the non-Hermitian PT -symmetric quantum mechanics remains safe and deserves to be advocated irrespective with the orthodoxal mathematical (though rather fragile) Hermiticity requirement. 13
