Tren is a script drug in Germany (ever heard of Parabolan), India, and I think at least one other country, but this is irrelevant, as a drug doesn't have to be approved for human use in order to be human-grade. The term "human-grade" simply means pharm-grade, which means the product was produced under GMP guidelines. All AP products products are produced in this way. AP recently put out a video showcasing their facilities and production process.
Also, I am not sure who you are asking to "post links", being that only one person has posted in this thread in the last 4 months, but if you want to know information ona certain subject, I suggest you search for it yourself, rather than asking other people to do your homework for you. I could understand asking someone to post links if they are trying to prove something to you, but no one is trying to prove anything to you...nor was anyone even talking about this subject. I suspect you could find some links with a little searching.
Lots of links for Parabolan, as I stated i was curious about tren a and tren e. Not trying to prove anything just looking for guidance, or should I take everyone on the nets word because everything on the net is true ??? Maybe you could provide links to their current medical use apparently my googler is broken, thanks.
