I spent about 2 weeks trying to have a generic finasteride tablet from India assayed before we recommended that particular provider to our users. I wanted to be sure it was legit stuff.
It was explained to me that in order to do an assay for a specific chemical, it takes thousands of dollars to create a brand new "science experiment" and the equipment and measuring tools to do it. It quite simply was too expensive, unless you are able to find a lab that is already set up to do assays for finasteride itself.
Nobody really asks for assays of finasteride so my search for that hit dead ends. I concluded that getting a finasteride pill assayed just simply is not possible unless you have about $8,000 to blow.
