There is I believe some literature on ad hoc tests for this question, but the results of 

. findit lognormal 

do not show any Stata implementations. I'd recast the problem as one of estimating a model using either -glm, link(log) f(normal)- or -lognfit- (SSC).

Is there a test of differences between geometric means, assuming lognormal distributions?
