I found it in a mainstream site here. 30ml for $300, with free shipping for next Wednesday. It has classified as a "nutricional supplement" for bodybuilders. I didn't purchase it, but I guess now I'm in yet another list.
There are places to get it WAY cheaper than that. I started off buying single vials for big money until I found group buys. Once my wife started using them too it was going to be too damn expensive to buy single vials. You can get kits (packs of 10 vials) for a lot less money. Been doing this 2 years now!
