Forgive my skepticism and negative tenor in my first post, but I find this story not even remotely believable and to be a shameless promotion of a product. Nothing more.
I've taken a recreational 40mg dose of tadalafil (Cialis) before, and while the effects were indeed very powerful, I didn't get a 12-hour erection. I know others who recreationally use PDE-5 inhibitors, and while they get benefits, their experiences aren't as good as this 12-hour boner story.
If you had posted this story and said that you got these effects on Masteron and a PDE-5 inhibitor, I'd believe it. But off a natural product that's grossly overpriced? I just don't buy it. Sorry.
