Idea for supplements that aren't good for you

Hello, everyone.
I have an idea I would like to test. It's been bugging me for over a year now.
I think we all know the pain in buying pricey supplements to then try... and come to the conclusion they are actually bad for us. What I mean by bad is, that they make you worse. Not months later but the same or next day. Maybe they're herxes, maybe not. Either way, they are wasted money when you can't deal with more herxes or feeling even more worse. Maybe you can in the future when you're stronger or it's a more opportune time but in the meanwhile, your money is stuck in those supplements.

Or if you have products you don't need to take anymore. So I was thinking, wouldn't it be great if you could recoup some of your money? Or try supplements without paying the full price first..

So I was thinking of making a site, sort of like an ebay for supplements. But I have limited energy. So before I begin an undertaking like this, I need to know if people are actually interested.
