I've tried to ask them few simple question about the medicine they are selling. They've responded me once with a very general answer, it was clear they were either too lazy to check their information, or didn't know what they are talking about.

When I've called them on this they've got extremely agitated, and then started screaming and swearing at me.

Just save yourself this unpleasant experience.

I've oreded their Hyperzyme product, and been taking it for a month for my high blood pressure, and it did absolutelly nothing.

I don't know about their other products.

I doubt their work any better, and I don't have money and patience to try.
