Question on what will make this not show on a collegiate drug test

[redwings91]

just run test suspension right up until the testing. Lower the dose to 10mg per day for the 3 days before the test, to maintain a seemingly natural test:epitest ratio.

I was under the impression that any form of synthetic testosterone can be detected even if the dose used is only putting you at normal levels. The levels of carbon-13 are different or something.

Once the ester is cleaved off (or when dealing with test base), there is no difference between synthetic and natural. Test suspension is the best way to getting around a drug test as it has no foreign metabolites.
The only issue is the Test:epitest ratio.
