gear testing?

Hey bro's.
I have heard some other bro's on this board who have been concerned that their gear was real or not so they have mentioned that they sent it to a lab for testing to see the exact/specific ingredients...

I would like to find out more info on this. I have a couple amps of test I am concerned about and would like to get tested. Can anyone make any suggestions/recomendations as to what/where I can go to have this done?
I am in the St. Louis area.

As always - thank you in advance.

go to the lab section then click on faq/reciepe's. The thread on where to get it done is in there.

Thanks bro!
