I've never heard of a blood test being done in the off season, but in season, blood test would be a possibility. With all of the information I've gathered about the test I'd be facing, they're looking for metabolites and test-Epitest ratios. If the Test Epitest ratios are high, then they will use isotope testing to figure out what I was taking..
I've never had a problem with Gyno, but my only experience with AAS was Test-E, but I ran it with anti-e several years ago.
Thanks for the info brother. From what I've been told, I can get results at a low dose, and get away with it as long as I keep it 4:1. It's been awhile since I've touched the stuff, but beginners have had results on 250mg of Test-E a week. So it would make sense if I was getting 40mg/day (280mg wk) of pure test.
