Any particular reason you are looking for Bayer? We have a lot of great sources here with high quality legit proviron. You don't need Bayer to get that, and often times pharma grade is easy to fake. I can get you a price list for Biotech if interested
bayer is the originator and of course a quality product but you also need to remember those boxes and packages can be faked as well... you need to be well aware of that... i can recommend quite a few places with quality proviron that should ring a bell... samson supplies has extremely high quality as does bio tech, pharma lady, AY, Phurious... all have quality... you cannot go wrong with any of them
