I may have misunderstood, but are you seriously asking if Proscar is legit? It passed 12 years worth of clinical trials, got approved by the FDA, and got a patent. Does it matter what any of us think? Of course it works. I can type out the same paragraph for nolvadex but that would be redundant.
You seriously have to do a bit more research. Two minutes on google would have told you the truth about both of these compounds. Be careful about what you are doing with your body.
As for the proscar, don't order it. Just go ask for a prescription. If you show any signs of MPB you will get a Rx, it's a very safe drug.
