It all depends on how the test would be administered. If they're starting with a test:epitest blood ratio, then most likely yes it would show up as a positive. Now, if they're looking for something specific like metabolites of nandrolone or such, then it's a crap-shoot. I don't know of much imperial evidence to what the pro-hormones metabolize to. I would stop now, and get on post cycle therapy (pct) fast.
