So this chemical has shown its face on a decent amount of Vendors, even some i trust. I know it has strange name Kryptonite , but does anyone have any experience with such RC.... Or is this some kind fake RC scam?

If they don't tell you what's in it, don't buy it. Simple.
The post that named a source review site was deleted as well, if you hadn't noticed.
And i hope it goes without saying, if a source doesn't name whats in something than don't buy it!
