Best liquid fulvic acid ?

Hey I`m from the uk as some of you know

I`m kind of limited to ebay at the moment, I`ve been using GHE`s Diamond nectar looking to get another bottle of fulvic acid and wanted to know who makes the best one or what one is most concentrated ?

My options are

Green Planet GPF Uptake fulvic acid

Vitalink Fulvic

GHE Diamond Nectar



I`m half leaning towards Vitalink fulvic but Green Planet claim there`s is the most concentrated liquid fulvic the price of both are almost the same, I don`t really want to buy any of AN`s granny eggy`s stuff as since AN was found to have heavy metals in some of their stuff I avoid it now just got a bottle of liquid silicone of there`s to use before I`m free of their products lol.

I`ve still got about a week to make up my mind I`m hoping someone has good news about green planets stuff.

So no one knows ? Guess I`ll take a gamble on GFP in the new year.
