I'm sure some of the people here will chime in, but here are a few thoughts...
I guess you've watched this video:
which is me talking about it with the "If it seems to good to be true, it usually is warning... (followed by the why it is not)"
If you scroll down to the bottom of the page there are a couple of links called "Why Trust FixHepC?" and "Scam Check FixHepC" - unusual stuff to put on a scam website and there to help people not get scammed.
On this forum you can see thousands of patients talking about it since 2015 - that history is your best reassurance.
Anybody can create a fake website, but only time can create history. With time the truth eventually comes out.
Have a look at this BBC video from 2 years ago of Sean Reddin.
At 5:32 seconds in you will see some bottles with both my name and his on them. That was a very long time ago
If you have a look at this one, which has 1/2 a million views and 150 patients putting their comments and real names on it including Sean...
It's not a scam, but if it was, you would have to admire our attention to detail!
