Just being curious instantbust

[Blazer22]

I was curious and please forgive me if this is the wrong place to put this thread.
A while back I was thumbing around surfing when I came across the ad for instantbust. They have this gel that in minutes after rubbing it in your breast causes them to grow and stay big for about 5 hours before it wears off.
Its done by vasodilatation
With regular use it's supposed to be permanent.
I was curious if they're blowing smoke or does it work?
Just curious........
