Drug testing aint joke … it is a serious matter and if you can find your way around it … power to you … finding away around the system that you follow doesn’t mean disobedience.
Athletes are required to sign an agreement, which can be found on the last page of the
IFBB Anti Doping Rules (pdf), which includes:
4. That I will comply with and be bound by all of the provisions of the IFBB Anti-Doping Rules, including but not limited to, all amendments to the Anti-Doping Rules and all International Standards incorporated in the Anti-Doping Rules.
And the rules (same pdf file) state that just possession of a prohibited substance is enough to get you disqualified (rule 2.6). Use of prohibited substances is a violation of the rules, whether you get caught or not (rule 2.2).
so signing that agreement and continuing to use banned substances is most certainly disobedience, and is dishonorable.
