Has anyone heard of or used these...

These are some 'natural' preservatives. I know the general consensus will be that these aren't suggested to use. But have any of you tried them and challenge tested? I was reading a thread from some folks of 9 years ago but no conclusive results were given.

Naticide
Biopein
Neopein
Suprapein

I have already requested samples of these and plan to test them out ( microbial/ lab testing eventually). Just curious if any of you have info on them?

Will be following.. not very hopeful though.

I've seen a couple of them but have never used any of them. Don't have high hopes for them either. I'll stick to preservatives that have been tested and proven to work.
