st: Asymmetric kernel estimators

I am looking for a way to use asymmetric kernels in kernel density estimations, for example a gamma kernel (Chen 2000). Unfortunately, I have not been able to locate any implementation in Stata.

Am I missing something or has anyone implemented an asymmetric kernel estimator in Stata (my data is more or less from a gamma distributions, non-negative by definition)?
