Stana has a very short 1/2 life, will be totally out of your system in a month, google Ben Johnson, will tell you how he avoided and eventually busted using it.
Do you really want a medal and photo like that? Even if no one else finds out, you will know and probably hang your head every time you look at it.
PS
Forgot to mention, if you keep training solid you will carry over most of the strength gained (including size so weight will change), you'll still be strong months after it clears.
