BioBoost from GA?

[svalli]

I found on garage shelf a half bottle of Gardens Alive's BioBoost. Has anyone tried it? I purchased it couple of years ago and used it then, but later forgot the potion. The seller website used to show tomato harvest with and without it and now it has photos of potatoes. I found nowhere any real testimonials by users, so I do not know if it is just false advertisement.

The bottle says that it should not be affected by freezing, so the stuff may still be as good as originally (if it was ever any good). I'm not sure, if I should try it on my plants again. I do not remember it causing any harm, but I did no control test so I do not know if it helps either.
