Let me add my first-hand experience to this thread, apologize for the long read in advance, but hope there is something to be learned from this.......
The year was 1998, I pissed off my then current girlfriend and she called Navy Criminal Investigative Service (NCIS), like any LE they HAVE to investigate ALL allegations, so they did. She accused me of taking, possessing and distributing Anabolic steroids on government property (the base), got a phone call from NCIS to come down to their office to talk, they would tell me what it was about once I got there. I arrived and was told to go to this small room and wait for a minute, in walks two agents and start to inform me of my rights and read the accusations and such, they ask me if I want to make a written statement, so I proceed to do just that to proclaim my innocence (a piece of advice, NEVER DO ANYTHING WITHOUT A LAWYER'S ADVICE, NOTHING!) those bastards can twist anything around to fit their side of the case and you won't even know it until it is too late. After proclaiming my innocence, going through multiple voluntary searches of my vehicle, barracks room, gym locker and storage facility and them not finding ONE piece of evidence to support their case that I was taking/possessing/distributing steroids, I was instructed to report back to my Commanding Officer, who then asked if I would do a voluntary urinalysis for steroids....I agreed. After waiting what seemed like an eternity, but was only 3 weeks, the report from the Olympic Drug testing Lab at UCLA came back.......it was positive for Nandralone metabolites, OH ****! But at the very bottom of the report, the last sentence read something like this "This positive finding for Nandralone metabolites can also be caused from legal OTC substances" (prohormones). Since they are now illegal, don't look for that sentence at the bottom. That was not the end of the case but it was enough in my favor for the Commanding Officer to drop the charges and both of us continue with our lives. I went through hell for approx 12 months with the investigation and accusations and such, but in the end I stuck to my story of innocence and beat the case with the help of a good military lawyer (which is a rare find) who also liked to workout and was taking legal PH's. It is extremely hard to prove and make a case stick in regards to steroids in the military, they almost have to catch you in the act of possession or use for a conviction or court martial.
NEVER UNDERESTIMATE A WOMAN SCORNED!!!!!
