One of the primary purposes of this group is to help one another. That involves keeping each other informed and what to do if you suspect anything.
First and foremost the best legal expert on the subject is Rick Collins. You can read his presentation here- http://www.drugpolicy.org/docUploads/PUMPED051006.pdf
If you cannot afford to hire someone like Rick and you needed too, then make sure your attorney is well versed and has read his presentations on how to defend cases involving anabolic steroids.
Secondly - watch this video on Do Not Talk to Police
The video is about 50 mins long but is important to watch and learn.
Thirdly- Get the book Legal Muscle- Anabolics in America from Rick Collins. He also has updates on his website. Well worth the money and read.
