To verify concentration?
Like i go give em 2ML of my test prop and ask em to test how much test prop/ml there really is in there? is it something like 100$ or more like 2000$?
and how about testing raw powder purity?
I bought one vial from a new supplier and would like to test it to b sure before i buy a dozen of them.
In my country it isn't illegal to possess steroids for personal use, so i would just go to my local lab, authorities wouldn't do much.
