Leaving aside the obvious faffing around making this stuff.
It might be me not understanding, but what would you actually use these liquids in?
If added to a boilie base mix, wouldn't the boiling process actually kill any 'benefical effects?
I get adding to a groundbait might work, as for a spod mix, wouldn't any effect just vanish in the volume of water in any lakes..... guessing a lot of this 'science' might have been tank tested?
