The recently developed 'resummed' cPT is illustrated in the case of pseudoscalar meson decay constants. We try to
get an estimate of the h decay constant, which is not well known from experiments, while using several
ways, including the generalized cPT Lagrangian, to gather information beyond the standard next-to-leading order.
We compare the results to published cPT predictions, our own standard cPT calculations and available phenomenological estimates.
