So you are saying you want to send your AAS that you purchased illegally to get tested. Brilliant!
This used to be common practice. Not all AAS are purchased illegally. Some members here live in countries where AAS are perfectly legal.
The lab Rimmy speaks of is closed for this type testing. I think there are others in foreign countries, but I have no idea who they are. I recall someone on BoS speaking of a lab that would test gear somewhere in Europe.
