There is an FDA study that was done (patient reported anecdotal evidence) of a decrease in Testosterone after 5-10yrs on Ambien.
The only problem with the results of the study is that the mean age reporting decreases was 60. Your testosterone from 55-60 would drop anyway so as they say: "Correlation does not imply causation"
Youre using exogenous testosterone so that itself will decrease natural testosterone production. So as long as the Ambien is well tolerated otherwise...it won't effect the outcome of TRT.
