Clarkia Drops v. Paragon,Parastoy(sp?)or Schultz 1&2

We are currently using Clarkia drops (two weeks now) and a rest period now and haven't seen a thing. Does anyone know if Paragon,Parastoy or Dr Schultz #1 and #2 is a better product? Or does it just take a longer time with ?Clarkia drops? Where is Paragon or Parastoy purchased? I would really love to see something working.

I would appreciate any info on these products.

Thanks
