If they test for testosterone they're going to look at the ratio of testosterone to epitestosterone. This initial screen is done on a urine sample by an enzyme linked immunosorbent assay on an automated chemistry analyser. Quick and relatively cheap.
When your body makes testosterone it also makes epitestosterone in similar concentrations.
When you take testosterone the ratio goes up. It gets even worse when you're shut down because you don't make any epitestosterone at all.
If they're actually going to do this test and you've been taking testosteone then things won't be back to normal until after PCT and full recovery. Sorry, but you're probably screwed.
The East Germans figured out how to beat this test - they gave their athletes epitestosterone as well.
To pick this up requires a gas chromatograph coupled to an isotope ratio mass spectrometer.
This looks at the ratio of carbon 12 to carbon 13 isotopes. It is different in naturally produced versus synthetic drugs. This test is more expensive and time consuming and is generally reserved for professional athletes.
Now there are stories of testosterone being synthesised with extra carbon 13 to beat this test. This is not the same gear you buy from a source on eroids. This gear is EXPENSIVE.

For USMC? I would be surprised if they checked test levels and even more surprised if they did an AAS test seeing how the Military uses the Olympic testing center which takes months to get back.
If they're doing a test for just your free and total, bring you dose down to 75mg a few weeks prior, take your test 4 or so days after your last dose and you should be right in the optimal range.
