Can Benzos Affect Blood Test Results?

Can clonazepam taken the night before a blood test affect the results while on trt? Or will the testosterone results still be accurate? I have read both cases were clonazepam or benzodiazepines can increase testosterone, and also decrease testosterone.

Continuous benzo use will basically make your TRT not work.

Might “increase” test by increasing your SHBG, making your Total Test “look higher” but it really isn’t. Decreases free test, and eventually ,long term use does lower test.

Long term benzo use and TRT don’t mix.

I just took 1 to help me sleep. I don’t actually take them long term or anything. Was just wondering if this one time use would alter next day blood test results.

Possible, but maybe only slightly.
